VS Dandong 3255 Integrated Replica Movement — “True 3235 Lineage” for Day-Date Builds

Why this movement matters
VS (Dandong) releases a true integrated 3255 replica movement: a 3235-based architecture with the Day module engineered into the base, rather than stacked add-ons. According to the factory, that’s why reliability is high while parts compatibility with the genuine layout is preserved.
Key highlights
-
Fully integrated 3255 architecture (not a 3135 conversion).
-
72-hour power reserve.
-
Rotor on full ball-bearing race with 27 balls (VS spec) — matches the genuine style.
-
Interchangeable components: many parts positions/shapes match the original layout, aiding serviceability and swap compatibility.
-
Cylindrical winding wheel axle form matches the genuine spec (not the screw-tail look of older 3135-based builds).

How to tell it apart (visual ID guide)
1) Rotor bearing & bridge details
VS 3255 uses a full-bead rotor bearing (27 balls) matching the genuine design. Shanghai “fake integrated” 3255 typically shows a 7-ball bearing and different finishing.

2) Under the Day disc (no ruby)
Open the weekday disc and inspect the plate: VS 3255 and genuine 3255 show no red jewel in this location. Movements built on 3135 lineage usually reveal a red jewel, giving the conversion away.

3) Calendar train geometry
On the VS, the change wheel, calendar positioner, and quick-set four-tooth gear mirror genuine shapes and placement. Conversions often reuse 3135-style parts and spacing.

4) Stem & keyless works
The setting stem profile and yoke/setting-lever structure on the VS replicate genuine 3255 geometry; 3135-based builds keep the older 3135 structure.
Real-world benefits
-
Stability: integrated design means fewer stacked tolerances; the factory reports very low failure/return rates compared with cobbled 3135 conversions.
-
Service & mods: with positions/shapes matching the original layout, watchmakers have clearer references for assembly and adjustment.
-
Authentic feel: winding smoothness and calendar action emulate the genuine Day-Date experience.
