Underneath are two pictures displaying the VR3186 movement with various engraving. Take note this motion is definitely identifiable via the posture from the arms about the harmony bridge: both of those the beat adjuster (red arrow) and regulator arm (eco-friendly arrow) level inwards and there’s a fake defeat adjuster arm (blue arrow) going through outwards.
Even so, the SA3285 experienced holes drilled within the rotor mounting (blew arrow) to make it appear to be the rotor was jogging on ball bearings just like a correct 3285 movement (see below). This movement is of similar inferior excellent because the SA3186, so it should be averted.
It had been my satisfaction executing this comparison for RWI members. I have realized a lot below and It is only fitting to return the favor and assistance out. But as we constantly say: "There isn't any most effective rep." Click to extend...
Each are acceptable. The Glidelock is where by VSF shines. It can be much smoother and is particularly considerably closer to gen in terms of experience and Procedure.
As to the overview of which is healthier between Clean vs VSF, there is absolutely no "true' winner due to the fact Just about every factory has their robust details.
In spring 2025 we observed a new variation on what seems being a Shanghai 4130 movement that's labelled as an "A4131" in EWE factory Daytonas. Nonetheless it seems as though this is not just EWE silk screening the quantities "4131" onto a regular SH4130 motion. There are several variances through the normal SH4130 which make me think there is certainly another thing happening below. You will find the same old indications of this staying a SH4130 such as counter clockwise coil on the hairspring (orange arrow), plus the conquer adjustor (purple arrow) and fee adjustor (inexperienced arrow) are during the Shanghai design (While in contrast to the SH4130 these position outwards -- but shifting the adjustors to stage outwards is something Shanghai has been executing on the vast majority of its movements; hense why there are numerous SH32xx v2 names from the guide).
The hole concerning bezel and crystal is well managed, as well as the width of entrance and the height of aspect are identical to Individuals of Gen.
6mm in diameter. This means that daily Day that is definitely equiped that has a 2836 has excess Room Within the situation for tungsten ballast (see why I like the expression "ballasted" for these watches?)... While in the graphic down below of the 40mm Working day Date rep that has a 2836 movement that has a movement spacer ring to make sure that it suits snugly Within the circumstance (purple arrow). This spacer ring might be constructed from a substantial density substance like Tungsten-Copper and may add Rather a lot of mass for the check out.
Ahead of this, other factories have been working with Erroneous clean factory rolex cases, Therefore the lugs had been a little broader than Gen's, such as the broader strap. In lieu of adhering to the instance of other factories to save time and effort, Clean has adopted one to 1 scenario and bracelet.
For reference listed here’s the real Rolex caliber 3135. Be aware how there is only one arm (the conquer adjustor -- purple arrow) over the equilibrium bridge on the real movement. This is due to the legitimate movement features a “cost-free sprung” stability. That means to the real motion the velocity on the movement is regulated (i.e. changing how fast or gradual the movement operates) by modifying The instant of inertia from the balance wheel by using little weighted screws around the rim of your wheel (eco-friendly arrows).
Equally Clean and VSF are wanting superior, but the sting goes to Clean with tighter tolerances and a far more good feel and appear.
I wont say too much my own position of sights about the goods this time, but will put up loads of real comparison images so that you men may have an intensive seem on them yourselves.
This can be an Asian clone of the ETA 7750 movement. The key reason why that this motion isn’t great for the Daytona is as it is thicker compared to the 4130 motion, so the movement is commonly slimmed down (and thus designed significantly less reliable) to fit within a twelve.4mm thick Daytona case. On top of that, the Daytona has its little seconds at 6 o’clock, but it's not the default place to the compact seconds complication within the 7750 motion; various further wheels must be included to the top in the 7750 motion for getting every little thing into the right situation.
Also to include a collage of the several 318X GMT movements (thanks @KJ2020 for this). And added a reference to @CTime Image comparison thread concerning gen and Dandong 4130 movements.
