There are 3 types of watch movement

Manual Movement
Automatic Movement
Quartz Movement

Quartz – the movement causes the second hand to move in individual ticks. Mechanical – the movement will cause the second hand to move in a smooth sweeping motion. Automatic – kinetic energy from the wearer's wrist is transferred automatically to drive the mechanism inside the watch.



ETA 2824-2 is a common automatic ETA movement and is found exclusively in replicas that need a standard dial as well as a date wheel. It has 28800bph – beats per hour. Often used in Rolex replica watchesBreitling  and TAG Heuer fakes.
ETA 2836-2 is just like the 2824-2, except that it has a day/date function. Watches with ETA 2836-2 movement include 
Rolex Day-Date, Datejust.

Asian 2824-2 or Clone Swiss ETA2836-2 – Copy  of the Swiss ETA movement. This is a more recent movement and it works like the 21j, except that it beats faster at 28800 bph and is more accurate too.

Swiss ETA 3135 Or 3255 – It is based on Swiss ETA2836 automatic movement. Adjusted to make it set the time forward which is the same as original and looks the same as original 3135 too. 25 Jewels at 28800 bph.

In our own experience these movements are absolutely dependable. We never experienced having one of these movements damaged during shipment.

Asian 21 Jewel Automatic Movement

This one has a reliability rating of 5/5 which obviously means it’s very reliable. Some people refer to it as the Mingzhu Automatic Rolex movement, while others call them ‘Japanese’ or DG2813 automatic movements. These versions are generally reliable and inexpensive compared to the ETA movements. It’s capable of 21600bph.  The Asian 21 Jewel movement often has a Chinese in origin and it is very dependable. Most of the replica Rolex watches are 21 Jewel Asian automatic movement.



BPH is short for beats per hour or some others call it VPH (Vibration Per Hour). A watch that has 28800 BPH ticks this means the balance wheel produces this many number of swings clockwise and counter-clockwise hourly. Every swing is a Tick and the number of swings per hour divided by 1 hour or 60 minutes and 60s will tell you just how smooth the seconds hand works.

Swiss Daytona 7750 Movement vs AR Factory 4130 movement vs Noob Factory 4130 Movement


This movement has subdials at 6, 9 and 12 that dictate the half hour counter, seconds, and 12 hour counter in that order. ETA 7750 movements are used in the high-end Rolex Daytona replicas with the cheaper Daytona copies using Asian clone movements. This movement has working 3-6-9 Sub-dials. If you want a Daytona replica with all the three sub dials working you have to have a genuine ETA7750 or an Asian clone of the 7750 movement in your replica watch – there is no way around it. Most of the Chronograph automatic movement watches are with 7750 movements. replica Rolex Daytona Swiss Grade watch (Weakness: Case diameter is thicker than original)

To avoid damaging the delicate mechanisms of the Valjoux 7750b1 movement you need to follow the instructions listed below to take care of it:

If your Valjoux 7750b1 has DATE function, DO NOT ADJUST the date when your time is between 10:00 to 3:00. It will damage the internal gears unknowingly if you do that. The BEST WAY is to manually adjust the time to 6:00 and then adjust the DATE after that. 

If you are using the chronograph functions of the Valjoux 7750b1, always make sure that to start the stopwatch, you depress the pusher button on top and also to STOP the stopwatch, depress the same pusher button.

IMPORTANT HERE!!! Should I leave the stopwatch running or ?

NOT RECOMMEND! bad for the movt, increased wear. Why expose your watch to unnecessary, excessive wear? Also, the PR (power reserve) WILL drop by having the chronograph running all the time


ONLY after you STOP the stopwatch, then you depress the lower pusher button to RESET the stopwatch function. DO NOT DEPRESS the lower pusher button when the stopwatch function is running. ONLY Depress the lower pusher button after you STOP the chronograph.


The 4130 movement is thinner than the 7750. Noob 4130 closer to gen thickness. The 4130 is 6.5 mm, while the 7750 is 7.9 mm.

Rolex designed the Daytona's new movement to have the seconds at 6 o'clock. This sets the Daytona apart and makes it harder to replicate. Rep factories would use gears to move the sub dial positions. Fortunately, for ARF they only moved one the 9 o'clock subdial to the 6 o'clock while leaving the other sub dials not functioning. (Weakness: Fake 3 and 9 o'clock Sub-dials).  Noob Factory has fully functional 3 subdials. 

What is 21600bph and 28800 bph?

Do you know what is VPH or BPH?
VPH (Vibrations per hour)  and BPH (Beats per hour) is the same thing. VPH(Vibrations per hour) is a common notation for movements in watches today and can greatly help in deciding on the quality of a timepiece. I would share it with my fellows. Basically it breaks down to how many times a watch will tick in an hour, if you hold your mechanical watch to your ear and listen you should hear a rapid “tick-tick-tick-tick-tick-tick”, each of these ticks are what counts toward the VPH when calculating the frequency of the watch.
18,000 VPH or 2Hz (Classic manual wind movements)
19,800 VPH or 2.5Hz (Cheaper Chinese movements)
21,600 VPH or 3Hz (Lower frequency for automatics or manual wind)  – Most of the Japan Grade watches are 21600bph
28,800 VPH or 4Hz (Most common automatic movement, can also be speed of a manual-wind) – The best replica watch use Swiss ETA movement which is 28800bph. Original Tudor watches are 28800 bph.
36,000 VPH or 5Hz (Advanced movement, El Primero Zenith – in some Rolexes and TAG Heuers) – Not available in replica
43,200 VPH or 6Hz (Advanced movement, Audemars Piguet ChronoAP)  – Not available in replica
72,000 VPH or 10Hz (Advanced Automatic Movement Rate “Breguet Type XXII”)   – Not available in replica.
