Recently, the market has been flooded with claims of “Dandong 3235” movements being everywhere – but many of these are actually fake SH3135-based modifications. For collectors, knowing the difference is essential. Currently, VS Factory is the only brand with the exclusive genuine Dandong 3235 integrated movement. Here’s how to tell them apart:

Key Difference 1 – The Clutch Wheel
-
Genuine VS 3235 (Dandong):
Features a polished circular point – this is the real automatic winding clutch wheel, and it can move up and down during operation. -
Fake 3235 (SH3135 modification):
Uses a screw-fixed wheel that does not move. It is purely decorative and does not serve any functional purpose.

Key Difference 2 – The Yellow Adjustment Screw
-
Genuine VS 3235:
The yellow screw is identical to the original Rolex design and can adjust the balance bridge height. This is a true functional component. -
Fake SH3135-based 3235:
The yellow screw can simply be unscrewed and removed – it has no real function and exists only for decoration.

Why VS 3235 is the Standard
-
Exclusive to VS Factory – no other maker has the true Dandong 3235.

Fully functional architecture – not just decorative parts.
-
Closer to the Rolex original than any other replica movement on the market.
✨ For serious collectors, choosing the VS Dandong 3235 ensures you are getting the only replica movement that truly matches the Rolex Cal. 3235 both inside and out. Don’t be fooled by cheap SH3135 modifications – the difference lies in functionality, not just looks.
✅ How to Identify Genuine VS Dandong 3235 vs. Fake SH3135 “3235”
🔹 1. Clutch Wheel (automatic winding wheel)
-
Genuine VS 3235: Polished round dot → real clutch wheel, can move up and down.
-
Fake SH3135 “3235”: Fixed by a screw → cannot move, only decorative.
🔹 2. Yellow Screw on Balance Bridge
-
Genuine VS 3235: Yellow screw is functional → adjusts the height of the balance bridge (real regulation).
-
Fake SH3135 “3235”: Yellow screw is non-functional → can be unscrewed and removed, purely decorative.
🔹 3. Overall Construction
-
Genuine VS 3235: Integrated movement, architecture matches Rolex Cal. 3235.
-
Fake SH3135 “3235”: Based on older SH3135 architecture with superficial cosmetic changes.
🔹 4. Exclusivity
-
Genuine VS 3235: Only available from VS Factory – no other supplier.
-
Fake SH3135 “3235”: Commonly found in the market, often sold as “Dandong 3235” but it’s a conversion.
⚡ Quick Tip:
If the “clutch wheel” doesn’t bounce, or the yellow screw has no function → it’s a fake SH3135-based 3235.
