VSF vs Clean 3235 Movement
A deep teardown comparing the VS3235 and Shanghai/Clean 3235 clone movements: power reserve, finishing, and parts compatibility.
The Calibre 3235 is the beating heart of modern Rolex Datejust, Submariner 41, and Yacht-Master models. For years, VS Factory (VSF) and Clean Factory have competed for dominance, each utilizing a different version of the 3235 movement clone. Here is our direct, watchmaker-level comparison.
The Contenders: VS3235 vs. Shanghai 3235
It is a common misconception that all "super clone" movements are identical. VSF watches utilize the exclusive VS3235 movement (produced by the DanDong movement factory), while Clean Factory uses the Shanghai 3235 (or sometimes labeled as VR3235).
Power Reserve: The 72-Hour Test
The genuine Rolex 3235 calibre features a Chronergy escapement allowing for a 70-hour power reserve. Here is how the clones perform in our workshop:
- VS3235 (DanDong): Consistently delivers 70 to 72 hours of power reserve on a full wind. It uses a longer, highly efficient mainspring housed in a thinner-walled barrel, perfectly matching genuine specifications.
- Shanghai 3235 (Clean): Generally achieves 40 to 48 hours of power reserve. While highly reliable, it utilizes a standard mainspring setup that does not match the extended power reserve of the genuine caliber.
Decoration, Finish, and Engraving
Under a loupe, the aesthetic differences between the two clone movements become obvious:
| Feature | VS3235 (VSF / DanDong) | Shanghai 3235 (Clean) |
|---|---|---|
| Sunburst Finish | Very fine, radial lines; highly reflective. | Slightly coarser brush pattern. |
| Engraving Color | Deep gold, sharp lacquer fills. | Bright gold, occasionally exhibits minor bleeding. |
| Balance Wheel | Glucydur look-alike, correct balance wheel shape. | Correct shape, but regulator arms are slightly visible. |
Genuine Parts Compatibility
For collectors who like to "frankenshare" (modding replicas with genuine Rolex parts):
The VS3235 is highly compatible with genuine parts. You can swap the balance bridge, balance wheel, pallet fork, escape wheel, and winding bridge directly with genuine Rolex 3235 parts. The Shanghai 3235 has several non-standard gear dimensions, meaning direct genuine swaps often require custom modifications.
The Verdict: Which is better?
The VSF VS3235 is the undisputed king of replica 3235 movements due to its authentic 72-hour power reserve and superior horological decoration. If movement replication is your main priority, choose VSF. However, Clean Factory's casing and dials remain top-tier, making their Shanghai 3235 watches still very viable if power reserve is not your absolute priority.
