What is the
difference between authorized dealers and the "gray
Authorized dealers obtain their watches directly
from the manufacturer or the manufacturer's authorized
agents. An authorized dealer is able to offer the
Manufacturers warranty, plus all official papers or
certificates, warranty cards correctly filled out,
booklets, and any other materials intended by the
manufacturer to accompany the watch. Authorized
dealers have access to manufacturer literature,
support, training, and parts. Gray market dealers are
essentially non-authorized re-sellers. Gray market
dealers obtain their watches from a variety of sources
all over the world, and they cannot offer an
manufacturer warranty. Because "Gray's" bypass
authorized channels they usually offer lower prices
than authorized dealers would. Some gray market
dealers offer their own warranty, however you can
never be sure about the quality of the person who will
work on the watch, their training, or their access to
parts, should the watch require repair. Some gray
market dealers do not offer all boxes and papers that
originally accompanied the watch. Some gray market
dealers deface watches by removing the serial number.
This can make the watch impossible to trace if stolen,
and it can render the watch uninsurable. Removed
serial numbers can have other consequences as well.
For example, in some U.S. states, a watch with the
serial number removed is legally presumed to be
How much can I
expect to pay for a new watch?
Many authorized dealers will discount their prices
from the list price, if you negotiate. Some will
discount more than others. It is not possible to make
blanket statements about the size of the discount you
can negotiate on a given model. Discounting and
pricing policies vary widely from country to country.
Within countries, discounting practices vary from
dealer to dealer, and even within the same dealership
over time. Discounts depend on several factors,
including your geographic location, whether you are
buying from the dealer's stock or special ordering,
the model watch you want to buy and demand for that
model, whether the model has been of will soon be
discontinued, the dealership's finances that day,
whether you are a regular customer or one time buyer,
and whether you are paying cash or using a credit
card. If you are purchasing from a dealer in another
country, currency exchange rates can also play an
important role. Another factor can be the timing
when you purchase a watch. Shopping between Christmas
and New Years is typically beneficial as stores are
looking to make sales for the end of the year. Also
shopping after traditional gift giving holidays, like
Mother's day, Fathers's Day, Graduation's, Valentine's
Day, can produce some better deals. Shop around and
see what you can find... Prices will likely
Discounts from a tenth to

affect resale value?
Resale value is affected
by several factors. These include the condition of the
watch, whether it is fully intact, running properly
and original (e.g. has all serial and other
identifying numbers in place), whether you have all
original boxes and papers, your location and that of
the buyer, the service history, the desirability and
rarity of the watch, and the nature of the buyer. When
you trade a watch in to a dealer, you will likely only
get wholesale value, just as when you trade in a car,
after all the dealer has expenses to meet and still
show a profit. You can typically get more for a watch
by selling it yourself to a "retail" buyer.
difference between an automatic and a quartz watch?
Which is better?
automatic is a testament to the
ability of watchmakers to put hundreds of
little parts into a watch case and get them
to work all together with close tolerances
just to tell time. An automatic watch
depends upon movement to power it while a
quartz watch uses electricity for its
power, typically a battery. It's a matter of
opinion as to which is better... But all of
those little parts mean that there are more
things to break. Manual watches do not
have a rotor to wind the mechanism, and rely
upon the user to wind them.
automatic/manual is usually more
expensive to repair than quartz, but
if you take care of the watch, you shouldn't
have to worry about this. The nice thing
about an automatic/manuals is that should
water get into your watch, it won't kill it
unless you don't have it serviced after the
leakage occurs. An automatic/manual
watch does not typically keep as accurate
time as quartz would, and if you're an
accuracy nut, this could get annoying.
Another drawback is that you will likely have
to reset your watch every now and then, which
causes wear on the gaskets and increases the
chance of water getting into your watch. Also
keep in mind that every time you let the
watch run out of power, you will have to
reset the time.
automatic can take some beating, but
not as much as a quartz. Manual
wind watches are usually somewhat tougher
than automatics as they don't have the
rotor spinning in the case. If you drop an
automatic, there is a greater chance
that something will be damaged. However, if
you take care of an automatic/manual,
it will last you a lifetime and you can pass
it on to your family. Also, should you decide
to sell your watch, an
automatic/manual is more likely to
fetch more money than quartz will.
Also, an automatic's second hand sweeps
nicely around the dial in a continuous
motion. Some people think that an automatic
has more of a "soul" than a quartz watch, as
it depends on the motion of your arm to power
watch is a testament to humankind's
technological know-how. A quartz watch
requires less maintenance than an
automatic. The only maintenance that
the watch will typically need is a battery
change and to have its gaskets changed
annually if it's around water. It is very
accurate, so this will stop you from having
to unscrew the crown and cause wear on the
gaskets. The down part to quartz is
that if water gets into your watch, it
usually means death to the movement. But the
plus side to this is that it will be
relatively inexpensive to replace a
quartz movement than an
automatic. The battery inside a
quartz watch can leak acid and corrode
the movement. This will usually happen if you
let an expired battery to sit too long inside
a watch after it dies. Thus it is a very good
idea to have a quartz watch serviced
immediately after its battery goes
- The great
thing about a quartz watch is that
it can sustain one heck of a beating and
keep on ticking. So if you're rough on
your watches, this is a major point that
you should take into consideration when
choosing which movement is best for you.
Another great thing about a quartz
watch is that you can take it off and let
it sit on your desk for long periods of
time and it will still be ticking when you
decide to wear it again. Unless the
battery dies, that is.
watch should last you all of your life if you
take care of it,. Some people argue: why buy
an expensive watch and take the risk of your
battery no longer being available? This is a
valid point, but if the past is any
indication of the future, Omega will continue
to support your watch for quite some time.
The second hand on a quartz watch
moves in one-second increments.
There is no "one better watch". One type of watch may
better for you than the other. The best person to make
that decision is you.

- With a manual
wind the activities that would be of concern would
be high contact/collision sports like Football,
Baseball, Polo, and the like. High recoil activities
such as target and trap shooting or hunting should not
be a problem unless you wear the watch on your primary
shooting hand (right wrist if you're right handed,
etc.). With shooting most of the recoil goes into the
strong or primary shooting hand. If you are shooting
pistol your wrist would typically be on off hand, with
rifle and shotgun your watch hand would typically be
on the fore grip and not as subject to physical shock
as your trigger hand would be as it is closer to the
shoulder stock. Of course if your active activities
include operating a jackhammer I'd recommend an LCD
Quartz watch like a G-Shock. That's what they are made
In all fairness an
expendable, inexpensive LCD Quartz watch is almost
always a better idea for high-risk activities than a
manual or automatic watch.
For automatics an
additional concern to the above are activities that
generate a great deal of torque or inertia at the
wrist/hands... Activities such as Golf, Tennis, Polo,
Baseball, Jai Lai, Lacrosse, and the like are likely
to cause the rotor to spin rapidly which is generally
not a good idea... Sort of like running your car close
to it's red-line at full throttle.
- Many mechanical and
automatic movement watches have endured long stints
in extreme active use and survived no worse for
wear. A number of movements are renowned for their
toughness. These include the Omega c.321, c.861,
Lemania c.1341 (Omega c.1040 and c.1041), c.5100
(Omega c.1045), Valjoux c.72 and c.7750, movements.
There are probably others.
- In all instances in
these cases the watches in question were:
- robust movements (not
a lot of delicate complications), and
- in good mechanical
condition and well serviced.
- However, it is
not advisable to wear an automatic for the "high
torque" activities mentioned above, a more robust
manual wind or a quartz would be better choices. I
would be more concerned about wearing an Automatic
watch when shooting than I would be a manual wind, not
only because of the rotor but also because there is
more to go wrong typically.
Additionally it is not
advisable to any vintage watch you were concerned
about repairing or finding replacement parts.
Certainly c.861 based watches are safe as they remain
in production and spares are plentiful, but it
would be unwise to wear a c.321 or a Valjoux
c.72 because of the increased difficulty of obtaining
proper repair parts since they have not been in
production since the late 1960's. The same would apply
to a Tuning Fork watch even though they are tough
watches, because they are uncommon, have not been in
production for many years and finding parts is
increasingly difficult. Wearing a chronometer (like a
SeMPC or a Speedmaster 125) should also be avoided in
order to preserve their accuracy... I'd also resist
from wearing a limited edition or limited production
watch for the same reasons.
How and how
often should I wind my mechanical watch?
Watches typically only wind when the crown is
rotated so that the top part is moving towards the 12
o'clock position. Some people only wind the crown
towards the 12 o'clock position and then turn the
crown back a few clicks so that the oil that is used
on the winding train doesn't sit on all of one side of
the gears. However, the mechanism is like a Ratchet
and it is intended that you can wind the watch with a
back and forth motion too. Some people use the back
and forth method. Either way is fine...
Wind the watch (either
method) until you feel increased tension. Do it slowly
the first couple of times you wind the watch so that
you can sense it.
Many people feel that
it's important to only wind the watch once a day.
There is a certain point to this (letting the watch
wind and unwind) as you operate the watch throughout a
range. However, if you might forget to wind the watch
you may overstep the power reserve. This happened
often during Gemini/Apollo space missions, the
astronauts would get so preoccupied with tasks that
they would forget to wind their watches and find that
when they needed them they had wound down. So many
people "top-off" the watch in the evening or a couple
of times (say morning, midday, and at night before
retiring for bed) during the day. Doing so would not
hurt the movement... Letting the watch run throughout
it's "range of motion" or power reserve from time to
time is probably a good idea. It might be a good idea
to let your manual wind watch wind down over the
weekend and wear a different watch during the weekend.
This will let the watch run over a full range of
motion on a weekly basis.
It is advisable to be
careful winding the watch until you become comfortable
with the procedure, then work into a routine you are
I own an
Automatic SeMP. How do you start it up when it's fully
Unscrew the screw-down crown to the first
position, and do 40 back-and-forth winds on the crown.
Then set the time and the date (as long as the watch
is not set to a time between 8pm and 3am). This should
power the watch so that it won't stop. Wear the watch
normally after this for the rest of the day.
If you wind the watch and
wear it all day, you should have a full power reserve
at bed time. You can then choose to wear the watch to
bed or not.

pool or shallow swimming [i.e. less than
or sea water hurt my watch?
If your watch is stainless steel, chlorinated water
will not hurt the watch. It's not a good idea to
expose your gold watch to chlorinated water, as the
chlorine can cause pitting of the gold. If you do take
your watch in a water environment often, have the
gaskets checked twice per year as chlorinated and sea
water will cause them to lose their effectiveness
However, it is a good idea to rinse your watch in
plain tap water (distilled would be better) after
swimming in a chlorinated pool or salt water.
Is it okay to
wear my watch while I shower (or hot tub,
There are some very good reasons not to.
Most people use soap or detergent (in shampoos) in the
shower. Many soaps or detergents contain abrasives, so
what you are essentially doing is putting an abrasive
in contact with your watch's crystal and finish. The
effect of such abrasive is not good, so why risk
Secondly, the primary purpose of soap or detergents is
to get water and oils to mix with one another so that
they can be removed (by the combination of soap and
water) from the body. So what you end up with is a
mixture of soap/detergent, water, oils and dirt.
Unless you are able to completely able to rinse this
out from all of the tiny cracks and crevices of your
watch's case, bezel, bracelet, etc. this slurry of
materials will accumulate in nooks and crannies on/in
Third, heat expands, cold contracts. Different
materials expand and contract at different rates. So
it makes sense that if you move from a 68F room
temperature into 100F shower water quickly, the case
and case back may expand at a different rate than the
rubber gaskets do, which may cause problems with water
Now, none of these items will cause a significant
depletion of WR in a watch if you forget to take off
your watch occasionally when you hop into the shower.
But why put the watch at risk unnecessarily?
What kind of
maintenance does my Omega need, and how often do
should I have it done?
If you have a mechanical or automaticmovement,
you should have it re-oiled every five to ten years
depending upon how much wear your watch gets.
If it's a quartz watch, you should have the
battery replaced as soon as it starts to die.
With either kind of movement, if your watch is
around water often, you must have its gaskets checked
annually. If it's not around water often, you should
have its gaskets checked every two to three years.
What is the best
position to leave my watch so that it gains or loses
the least amount of time?
Each watch is different when it comes to this. Whether
its dial-up, down, crown left, or right, depends
entirely on your watch. Experiment with the different
positions each time when you take your watch off, and
find out what works best for your watch.
My Omega needs
service; to whom should I send it?
If your watch is under warranty you should have it
serviced by Omega in the country you reside, or by an
authorized Omega dealer or service center. If you
purchased your Omega and the watch is under a gray
market warranty you should send it to the place you
purchased it from. If your watch is out of warranty
and you have a watchmaker in your area that you trust,
you have the option to use him or her. Typically this
would be cheaper than sending it to an Omega service
center. If you want to send it to an Omega service
center, the best one is at the factory in
Should I send my
watch to Omega for repair/battery/waterproofing, or
have my watchmaker do it?
You can do either one. Omega will give you a one-year
warranty on their warranty service, and most
watchmakers have a warranty on their work also. If you
have a watchmaker that you know, and trust, you can
take it to him, and that will probably be less
expensive then sending it to Omega.
I have a vintage
Omega, and Omega says that they don't have parts for
it. What do I do now?
This is the sad part of owning vintage watches, but
there is still hope. You can either find the same
movement and pull the parts out of it that are needed,
or you can try finding a watchmaker who knows how to
make parts. You can find a good list of watchmakers on
web site at
What does a
unidirectional bezel do?
Its prime purpose is to keep track of time under
water. It is unidirectional so that if it gets bumped,
it will only lessen the time left for diving (i.e.
bumped from 30 to 29 minutes). It can also be used as
a timer, elapsed time, and time zone indicator.
Can I change the
insert on my Seamaster from blue to stainless steel,
Yes you can, but it is a tricky job. Most watch makers
will tell you that you should buy a new bezel, because
if the insert gets bent while installing the new one,
it will put a permanent white line on that bezel
insert. If you want to change the color insert, send
your watch to an Omega service center near you.

the difference, a Stainless Steel Seamaster
Professional Chronograph tips the scales at 206 grams,
while its Titanium counterpart weighs a mere 142.7
grams - a savings of over 60 grams or more than two
How does the
helium release valve on my Seamaster work? Can I open
it on land?
The helium release valve works by letting helium out
of your watch, and nothing else in. This only comes in
handy when you are in a helium-saturated environment
such as a dive bell. You can open it on land, but make
sure you screw it back down before you submerge it in
water. Leaving it open while the watch is under water
can let water into the watch.

- How does Omega modify

- In addition to polishing
the components and adding the Geneve Wave decor, Omega
replaces the rotor with an Omega Specific (only) rotor
that rides on a small ball bearing. They change the
automatic bridge with a their own gear-train and
endshake corrector. Which in turn, reduces the height
difference between the auxiliary reverser and rotor.
This also allows the oscillating weight's gear to mesh
more precisely with the click wheel. This modification
reduces the rotor's play during movement, and also
prevents friction against the plate. On a standard ETA
ebauche, a metal seating is used to hold the barrel in
place. Omega replaces that, and uses two jewels to
hold the barrel in place. This improves the constancy
of the force flow and ultimately produces a more
accurate movement, and adds about 2 hours to the power
reserve. And to top all that off, add pure gold inlaid
engraving for the writing.

How does the
The movement in the Omegamatic is a hybrid movement
that uses the same concept as an automatic movement: a
rotor which rotates when the wearer moves, to generate
energy. However, instead of storing the energy
generated in a metal spring, the Omegamatic movement's
rotor moves a micro generator that creates electrical
energy which is stored into a capacitor. Then this
energy is transmitted to an integrated circuit, which
contains a quartz crystal whose oscillations are
driven by the integrated circuit. The integrated
circuit then sends the necessary impulses for the
functioning of a stepping motor which drives the
An Omegamatic can also create electricity by turning
the crown of the watch.
The benefits of such a movement is that you have the
best of both worlds: Quartz Accuracy, without the need
to change a battery every year or two.
How do I use the
non-listed shortcuts of my X-33?
The non-listed shortcuts on the X-33 are: Alarm,
Mission Alarm (MA), Universal Alarm (UA), Count Down
Timer (CDT). They can all be set by pushing in the
crown and holding it for 3 seconds until the function
flashes. This allows you to set these functions
without pulling out the crown, which can be hard if
the watch is on your wrist.
Why doesn't the
Speedmaster have sapphire crystal?
Omega uses the plastic/acrylic crystal because it
is shatterproof. While sapphire is scratchproof
(virtually), it isn't safe at very intense pressure
levels. An astronaute would have a very HUGE problem
if his sapphire crystal shattered at 0 G. That's why
it's used on the Speedmaster Pro and not on the
regular Speedmaster's, it's intent is to be a
professional Pilot/Astronaute's watch, in that respect
it does its job admirably, IMO.
Besides, a Hesalite
(plastic/acrylic) crystal can very easily be polished
out, but if you ever scratch/chip your sapphire
crystal, you will have to replace it or live with it
as Sapphire is so hard it's exceedingly difficult to
polish out any scratches...

Why wasn't an
Automatic Watch chosen by NASA?
One of the reasons that NASA chose a manual wind
watch for space flight crew use was that they wanted a
chronograph and automatic chronographs would not be
perfected until 1969. In addition NASA had the
mistaken belief gravity needed to be present in order
to cause the Rotor to work.
As Newton described
objects at rest tend to stay at rest unless acted upon
by a force. When the watch is moved, the rotor wants
to stay put. Since its center of mass (somewhere in
the middle of the rotor plate) is not its center of
effort (the rotor shaft), it spins. Along the way, it
winds the watch. However, what is important in this
equation isn't gravity, but rather Inertia...
To see a demonstration of
how Inertia works on a automatic watch take any
display back watch automatic or an automatic with the
caseback off and hold the watch with the dial down....
One can easily set the rotor spinning moving the watch
in a circular motion. Gravity doesn't play a
significant part, because the rotor is more or less
level gravity isn't acting on it in a significant way.
The inertia from from moving the watch around is what
moves the rotor and winds the watch. Inertia is a
So, Automatics will work
in Space. In fact if the watchmakers had been 5-10
years earlier with the creation of the automatic
chronograph complication, the moonwatch might have
sported a Valjoux 7750, a Lemania 1342, or a Lemania
5100 under the dial instead of manual wind

My new Seamaster
Pro automatic is running a few seconds fast/slow; what
should I do?
Relax. Like most mechanical devices, a new watch
has a break-in period that lasts for about a month or
so. During this time, your watch is distributing the
oil around, and is breaking in its gears. Its accuracy
will vary by a few seconds during this time, but it
will eventually settle down. The C.O.S.C. standard is
+6/-4 seconds a day. If it's running way over that,
return your watch.

does occur on certain types of chronograph movements
used by Omega (Lemania c.321 & c.861, and those
using Valjoux 7750 & 7751 base movements)
throughout the Omega product line as well as other
companies using these movements. Thus this is
not an issue that is restricted to any one
product line (Speedmaster, Seamaster) but can occur
with any watch using these movements. However,
it seems that watches using the Omega caliber 1045
(base movement Lemania 5100), 1040 and 1041 (base
movement Lemania 1341) do not seem to suffer from this
malady, or suffer at a much much lower rate
than the previously mentioned movements.
This problem happens because a spring that causes
tension on this register gets slightly out of
alignment. Sometimes carefully resetting the
chronograph can minimize this problem from occurring,
until you decide to have the watch serviced. Another
workaround is to simply press the reset button before
activating the chronograph function. Typically it's
not worth the time and expense to send the watch into
Service for just this problem if the watch is out of
warranty. However, you should ask for it to be
repaired the next time you have your watch in for
periodic service... If you ask the Watchmaker to look
into this the cost for repair shouldn't be much if any
greater than a typical service (clean and lube)...
Professional's bracelet shows scuff marks already. Is
there any way to stop it from happening, and can I
remove the ones that are already there?
The clasp on the Seamaster is known for its
wonderful ability to show scuff marks no matter how
careful you are with it. There are many ways that
people have found to take the marks off. Some people
use a polishing cloth, while others use other items
such as a steel wool scrubbing pad. It depends upon
what you feel most comfortable with, and what you find
insurance company insure a watch with missing serial
numbers and/or with out manufacture's warranty
Most insurance companies couldn't care less about
serial numbers. You can insure a vintage Omega with no
serial numbers, so why not a new one with no serial
numbers? Again, most vintage watches have no warranty
card and are fully insurable.
How can I let my
insurance company know how much my vintage watch, or
my watch with out a serial number is worth?
If they ask, an appraisal from a qualified person,
or a receipt will usually be sufficient.

I have a choice
of getting the Omega I want on either a Strap or a
Bracelet, which one should I buy?
Get the one you like, but keep in mind that you
can always obtain a leather or rubber strap for much
less than the metal strap purchased separately. Also,
the metal band will outlast a rubber or a leather
strap in the long run.
How do I remove
links from my Seamaster, Speedmaster, De Ville, or
You need the proper tools to do this. If you don't
have them, then it's best to take your watch to an
authorized dealer or a watchmaker. Omega makes a tough
bracelet, and they also make a secure one. There are
some tiny parts when taking apart the bracelet, and
they are easy to lose/bend. You wouldn't want to ruin
your beautiful watch by doing a do-it-yourself job on
it, would you?

about getting a winder for my automatic watch(es); can
this damage them?
There are two schools of
thought when it comes to this subject: Yes and No...
Some watchmakers will tell you that using a winder
will cause unnecessary wear to automatics, and wear
parts down faster. A winder is intended to keep a
watch that is used periodically wound, and not made to
help preserve a watch.
The other option is to
wind a watch by hand. In watches that can disconnect
the winding train when winding by hand (you have to
pull the crown out to wind the watch), there is
minimal chance of damaging the watch. In watches that
don't disconnect the winding train, wind these watches
slowly, and only turn the crown 10-20 turns. Rapid and
excessive winding will cause wear on the winding train
since they don't disconnect.
