They are really slender (as opposed to the 7750 motion, see below), and they are functionally similar to the 4130 on which They're based mostly. The motion in all fairness inexpensive, so It truly is possible to order replacements and obtain spare areas if a thing goes Erroneous. Having said that, the SL-4801/two rotor only winds in one way which implies Will probably be noisy mainly because it spins freely in another course -- a little something to bear in mind if rotor noise bothers you.
In Spring 2024 a 3230 "no date" Model of this movement was officially produced by Dandong. This movement can now be located in reps from VSF including their Oyster Perpetuals, Airking, and Explorer one. Many of such reps had been bought ahead of the new vs3230 was readily available, and were sold which has a vs3235 which experienced a phantom date place whenever you pulled out the crown.

There is certainly a simple method to differentiate the SH4130 within the DD4130: The posture and elegance of the beat and regulator arms on the equilibrium bridge. Not like the DD4130 where the defeat and regulator arms place outwards, around the SH4130 the defeat adjustor (purple arrow) and regulator (environmentally friendly arrow) point inwards.
Note, in November 2024 we noticed the discharge of a different current version of the SH3285 from the QF Explorer two (however it's Risk-free to believe this update will shortly be seen in all GMS and Explorer 2s made by factories that previously employed the older Variation of your SH3285). Similar to the updates to all the opposite Shanghai movements which we initial noticed in the summer of 2024, the update towards the SH3285 gets rid from the phony shock setting within the stability bridge and moves the defeat adjustor (Crimson arrow), and regulator (eco-friendly arrow) to position outwards like we have usually witnessed on Dandong actions.
The two Clean and VSF are searching excellent, but the sting goes to Clean with tighter tolerances and a more reliable feel and appear.
Lucy is truthful and Tremendous-detailed in her QA of my watches. I can mention the amount function she does past what I'd be expecting from any dependable dealer but I want to be cautious right here due to the fact I have no idea if she does what she does for me is identical of what she does for all of you. I think she does nevertheless and that's simply because she has clean factory rolex outstanding operate ethics.
However, this motion just isn't going to operate like a genuine Rolex GMT movement, and it has the wrong hand stack to the dial. A far better possibility is to go with the VR3186 or perhaps the newer dd3285. This motion is simple to recognize from the ETA model balance cock assembly (pink arrow).
diamonds reported: I not too long ago picked up a real Rolex Submariner 124060 from my regional AD, and I chose to purchase the Clean and VSF versions to try and do an entire comparison for the reward all customers at RWI.
You'll find three seen variations in the AR4131 in the DD4130: one) The column wheel is different (black arrow), two) the vertical clutch jaws and spring differs (cyan arrow), and three) the hammer spring has been peened (orange arrow). Additionally, thanks to the Original movement tear down by @CTime we realize that the rotor only winds the mainspring in one route (Therefore the rotor will spin freely / loudly in another path). A complete teardown of your motion is also out there. This doesn't appear to be a "real clone" 4131 but fairly a medium work endeavor at generating an affordable off the shelf chronograph motion seem like a 4131. As of January 2024, I'd personally propose waiting around till there are other 4131 actions possibilities accessible.

I wont say far too much my own position of sights concerning the solutions this time, but will post a great deal of serious comparison photos so you fellas might have a thorough appear on them yourselves.
As regular, the movement is VR3230, with motion code engraving within the mainplate. The cleats and gears are polished in all positions.
As with the assessment of which is healthier among Clean vs VSF, there is no "actual' winner since each factory has their robust details.
