Rolex DateJust 31mm Ladies 904L WF Diamond Purple Dial Diamond Roma Marker Oyster
Craftsmanship & Technical Specifications
Atelier Description & Craftsmanship
Put the Rolex DateJust 31mm Ladies 904L WF Diamond Purple Dial Diamond Roma Marker Oyster on a digital scale next to a boutique example and the numbers match within a fraction of a gram. Machined by WF Factory from Solid 904L Oystersteel (Satin & Mirror Finished), this reference pairs a 31MM (1:1 Oyster Case Profile) silhouette with an anti-reflective sapphire crystal that eliminates milky edge distortion. Inside beats the Calibre 2236 Automatic Clone (Instant Date Jump) (55-Hour Power Reserve (28,800 vph)), giving the seconds hand a crisp 28,800 vph (8 ticks per second) sweep.
Calibre Stability, Power Reserve & Case Finishing
Where cheaper builds cut corners on bracelet articulation and rehaut laser etching, WF Factory chamfers the underside of every link so the watch drapes naturally across the wrist. The crown threads down onto twin Viton O-ring seals without grit or play, and the dial markers sit dead-center against the minute track under 10x loupe magnification.
