Building a convincing 1:1 edition of the Rolex Cosmograph Daytona 116519 Grey Dial Cal.4130 comes down to two things: case metallurgy and movement geometry. Clean / VS Factory mills the chassis from solid Solid 904L Oystersteel (Satin & Mirror Finished) (40MM × 12.2mm (1:1 Case Profile)) and fits the regulated Dandong DD4130 / SH4131 Integrated Chronograph automatic movement delivering 72-Hour Extended Reserve (28,800 vph).



### Case Geometry, Dial Execution & Bracelet Fit


Every external contact point, from the milled folding clasp safety catch to the knurled winding crown and bezel teeth, carries the tactile resistance expected of a Geneva timepiece. We inspect the dial printing, hand alignment, and sapphire gasket seating on every single unit before it ever reaches the shipping desk.
