Collectors who know Clean / VS Factory recognize the difference the moment they wind the crown on the Rolex Yachtmaster 40mm Steel Dial 904L Steel. Rather than dropping a noisy generic rotor into a thick shell, this build is engineered around the 1:1 Cloned Swiss Automatic Calibre (28,800 vph) (48–70 Hour Power Reserve) so the hand stack height, date window depth, and 40MM (1:1 Factory Dimensions) lug profile mirror the factory schematic.



### Inside the 1:1 Cloned Swiss Automatic Calibre (28,800 vph) Architecture


The Solid 904L Oystersteel (Satin & Mirror Finished) case combines fine directional satin brushing along the top lugs with mirror-polished bevels that catch light cleanly without rounded edges. Topped with scratch-proof sapphire crystal treated with colorless double-sided anti-reflective coating, the dial reads clearly even under harsh studio lighting.
