Put the Rolex Daytona 126519 40mm UFO Gray Black Subdial Oysterflex UF4131 Free Sprung on a digital scale next to a boutique example and the numbers match within a fraction of a gram. Machined by Clean / VS Factory from Solid 904L Oystersteel (Satin & Mirror Finished), this reference pairs a 40MM × 12.2mm (1:1 Case Profile) silhouette with an anti-reflective sapphire crystal that eliminates milky edge distortion. Inside beats the Dandong DD4130 / SH4131 Integrated Chronograph (72-Hour Extended 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, Clean / VS 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.
