One of the more common
automatic ETA movements. Commonly found in replicas
requiring a standard dial and date wheel. Beats at 28,000
BPH (beats per hour) A Chinese made
clone of this movement is now available, featuring the same
specifications but produced locally here in China.
This movement is no more or less
reliable than any other ETA movement.
Similar to the 2824-2, but this one allows for day/date
function. 25 jewels, 28,800BPH.
The 2836 is a commonly used movement is many
no-complicated replicas. Due to a
shortage of original ETA movements from the SWATCH company,
the price of authentic Swiss made ETA movements has
increased. As a result, a cheaper
locally made clone of this movement has now become available
as an alternative for customers who do not wish to spend the
extra money for a Swiss made ETA movement.
thinner movement similar to the 2824-2. This model is also
capable of 28,800bph. This movement is
typically nickel plated and is more expensive than the 2824
or 2836, however it is not “better” or “more reliable”.
Originally it was a 28mm wide movement,
but ETA reduced the size to around 25mm to make it
compatible with a larger range of watches. It
is physically smaller than a 2824 or 2836 movement, which
contributes to the increase in price. It
is capable of using a date wheel.
important to note that physically and design-wise, the ASIAN
ETA 2824-2 is identical to the original Swiss made ETA
2824-2 movement. That is to say that the “Asian” ETA
movements, all of which are produced in China, are direct
copies of the original Swiss movements. That being the
case, these movements do not go through the same rigorous
quality control tests that would be conducted at a Swiss
factory. Regardless of that, the “Asian” ETA movements
provide a cheaper alternative for customers who wish to
spend less money on a watch with the same external
Whenever you see a watch advertised as being available with
either “Swiss ETA” or “Asian ETA” movement, it means that
this watch comes from the same factory, however the producer
offers the choice of installing a more expensive Swiss made
ETA movement, or a cheaper locally made clone, or “Asian
ETA” movement. The external case, dial, hands, crystal,
band etc will be IDENTICAL between the two choices. Only
the movement will be different. When asked the different
between an Asian ETA 2836 and a Swiss ETA 2836, the answer
will be “One is made in China, the other is made in
Switzerland”. In both cases, the other watch components
will all come from the same place in China. There is no
external quality different between an “Asian ETA” and “Swiss
ETA” watch shown on our site.
21 Jewel Movements
is one of the most common automatic movements used among
cheaper watches. There are many versions of this movement.
Most have proven to be reliable and affordable alternatives
to the more expensive ETA and Asian ETA movements.
The Asian 21 Jewel movement is almost
always Chinese in origin, and it is a work horse movement.
Extremely reliable, for long periods of time, this simple
movement typically just has one set of hands and sometimes a
date wheel. The simplicity of the movement itself makes it
very reliable despite it’s lower price.
Asian 7750 movement is a Chinese made partial copy of the
Swiss ETA Valjoux 7750. It is an
automatic chronograph movement capable of running up to
three sub-dials and a date wheel. The
sub-dials can be in the 3,6,9 positions on the dial, or the
6,9,12 positions. It has a functional
stop watch feature as will as independently running
sub-dials which in most cases function exactly as the
original authentic watch would. The 7753
has a pusher allowing the date to be changed via depressing
the pusher, while the date on the 7750 models needs to be
adjusted via the crown. The Asian 7750
has improved drastically over time.
Several years ago, the older 21,600BPH versions of
the Asian 7750 were literally hit and miss. These
days the movement has been improved to the point where many
non-chronograph watches still use it. In
general, it is a reliable movement when treated properly.
If you drop your watch on a hard floor surface, the
7750 is more prone to damage than a non-chronograph movement
would be. For 7750 versions, it is
necessary that you not change the date when the watch time
is displayed between 10 and 2, as this will damage the
keyless works in the movement. Please
adjust the time out of that range before changing the date.
This movement is generally operated by weighted rotor
that “charges” the watch as you wear it. The
top pusher generally stops and starts the sub-dials and main
seconds hand. The bottom pusher
generally resets them.
notice that on our site, VERY FEW watches are shown to have
this movement. You’ll notice that on other sites, many
watches are claimed to contain this movement. In reality,
VERY FEW replicas use this movement because it’s EXPENSIVE.
Furthermore, the limited supply of the Swiss made 7750 lends
it poorly to mass produced replicas. Many sellers lie and
claim that their watches have these movements in order to
persuade more gullible customers into parting with their
The Swiss made Valjoux 7750 has a date wheel that is less
shallow than the Asian 7750. This means that if you were to
try to install a Swiss valjoux 7750 directly into a watch
that is designed for an Asian 7750, it would not fit. This
is why you see very few actual replicas using this movement.
The dial and other components must be specially modified to
accept a Swiss 7750. This movement is offered only in
watches that have a history of being high-demand items,
where customers are willing to pay several hundred more
dollars for the Swiss 7750. In reality, the cost/value for
installing a Swiss 7750 into a replica watch and then paying
$900 for it is debatable. Replica watches after all have
little to no resale value, and for the cost of a
7750 installed in your watch, you could often times buy two
or three Asian 7750 watches.
6497 Hand Wind Movements
The 6497 movement is
used in larger hand-wind watches such as Panerai, IWC FA
Jones, Omega Railmaster and other large replica watches.
There are both "Asian" and "Swiss" 6497 movements available at
differing prices. The average difference is about $100. A
simple rule to always follow; wind the watch until it stops
and you can't wind it anymore. Until and unless you have
reached the full stop and can't wind anymore, you have not
fully wound the watch. The Asian 6497 models may be
slightly more sensitive to harsh over-winding, where the
user fully winds the watch, and then, despite the resistance,
continues to attempt to wind it and eventually breaks
This movement beats at 18,000 BPH. Power reserve is 46
hours. This movement has been around in one form or another
for over 70 years, and was used in vintage pocket watches.
After shipping these movements out for quite some time, it has
been our experience that watches based on these movements are
very seldom damaged during shipping. Also refered to on our
site as "Basic 6497" and "Upgraded 6497". The "Upgraded"
version usually refers to a 6497 that has a swan's neck
regulator and other minor upgrades.
The Venus 175 Movement
manual wind. Good movement, well designed and built, does
suffer from jerky seconds hand once in a while. Not bad as
delivered, clean, oiled so and so. 21,600 BPH. Typically seen
in Omega Moon watches, Roger Dubuis, some discontinued Panerai
models, and other assorted brands. It has been our
experience that these movements are extremely reliable. We
have never had one of these movements damaged during shipping.
What is BPH?
BPH is the number of
beats per hour. A watch with a 28,800 BPH ticks and tocks
28,800 times per hour, meaning the balance wheel makes this
number of swings clockwise and counter-clockwise every hour.
Each swing is a "Tic" (or Toc) and the number per hour,
divided by 60 minutes, and 60 seconds, will tell you how
smooth the seconds hand runs. In this instance, you have 8
"Ticks/Tocks" per second, and the hand will appear to "Sweep"
across the dial, this is the smoothest you can get. Other
common BPH are 21,600 (7750, Venus 175) 6 ticks per second,
and 18,000 BPH (ETA 6497-1 manual wind PAM models), 2.5 ticks
per second. This is why older 7750 movements do not sweep as
smoothly as ETA movements or newer 7750 movements. This is
also why watches that use the 6497 movement typically do not
have seconds hands in the center, but usually as a smaller
What About Water Resistance?
A watch which is indicated on our site as
water resistant is designed to withstand accidental splashes
of water only. Do not submerge such a watch. Higher levels
of water resistance are possible, please email us regarding
specific models. There are a variety of ways to make a
watch water resistant. All such watches use rubber gaskets
or "O" rings to seal the case back and crown tube. A watch
with a back that screws onto the case provides a higher
degree of water resistance. Some crowns (the "winding stem")
actually screw into the case to further increase water
resistance. Please note that we do not recommend
swimming or diving with your watch unless it has a
screw-down crown (also known as 'screw-lock' or 'screw-in'
crown) and is water-resistant to at least 100 meters.
