Craftsmanship & Technical Specifications
Atelier Description & Craftsmanship
The Rolex DayDate 40mm Gray Dial Lume Marker President (Catalog Ref. SW-25554) represents Clean / VS Factory‘s latest production batch, combining Solid 904L Oystersteel (Satin & Mirror Finished) construction with the 28,800 vph 1:1 Cloned Swiss Automatic Calibre (28,800 vph). With 40MM (1:1 Factory Dimensions) proportions and 48–70 Hour Power Reserve, it delivers the exact visual depth and mechanical cadence collectors look for.
Metallurgy, Crystal Clarity & Wrist Balance
Pay close attention to the transitions between brushed and polished surfaces along the case flanks and bracelet center links; each edge is hand-finished after CNC milling. A colorless anti-reflective sapphire crystal seals the dial against dust and moisture.
