VS Factory has finally developed the Cal.3255 movement. You may regard this movement as an integrated‑movement variant for Rolex’s day‑and‑date complication. Prior to this release, we would recommend the 2836 movement for Day‑Date replicas, since modified aftermarket Cal.3255 movements on the market suffered from poor stability, as outlined below.

Brief overview from VS Factory: VS presents the brand‑new exclusive genuine integrated Cal.3255 movement manufactured in Dandong. It is a true integrated unit built upon Cal.3235 architecture paired with a day‑date module. This is not the patchwork Shanghai‑made fake integrated movement built on the older Cal.3135 base found elsewhere on the market. The genuine integrated movement delivers outstanding stability with nearly zero repair rates. By contrast, fake integrated movements assembled from mismatched parts suffer high failure rates.

1. All components of the VS Cal.3255 are interchangeable with genuine parts; it delivers a 72‑hour power reserve.
2. The rotor of the VS genuine integrated movement matches the original, fitted with a full‑ball 27‑ball bearing. Shanghai fake Cal.3255 units only use a 7‑ball bearing.
3. The shape of the winding intermediate wheel arbor on the VS movement follows the genuine flat‑cylindrical design. Older modified movements converted from Cal.3135 adopt a screw‑shaped arbor.
4. When the day disc is removed, the VS genuine integrated movement has no ruby jewel, matching the genuine Cal.3255. Shanghai fake Cal.3255 movements inherit the Cal.3135 platform and retain the ruby jewel just like the original Cal.3135.
5. VS independently developed this genuine integrated movement. The geometry of every component including the date change wheel, date positioning mechanism and four quick‑set date gears are identical to the genuine.
6. The stem profile and yoke mechanism of the VS genuine integrated movement conform to original specifications. Shanghai converted “Cal.3255” still retain the underlying Cal.3135 structure with incorrect mechanical lineage.

Should this watch receive positive market feedback, VS Factory will likely roll out additional dial colour options. Customers may wonder whether to choose a single‑date or day‑and‑date model. Here is a general guideline: many genuine Rolex Day‑Date watches are crafted in white gold and belong to precious‑metal collections. If you cannot afford the price point of such genuine pieces, the Datejust is the more practical choice. One genuine white‑gold Day‑Date costs enough to purchase multiple Datejust watches. It would be awkward to stumble when others ask how much your watch cost.
