Rolex Daytona 116508 BTF Dial Black Subdial
Craftsmanship & Technical Specifications
Atelier Description & Craftsmanship
Most buyers can spot a low-tier copy from across a table by its thick bezel lip and jerky 21,600 vph seconds hand. The Rolex Daytona 116508 BTF Dial Black Subdial by BT Factory (BTF) solves both: it runs the high-beat Dandong DD4130 / SH4131 Integrated Chronograph (72-Hour Extended Reserve (28,800 vph)) inside a slim 40MM × 12.2mm (1:1 Case Profile) housing milled from Solid 904L Oystersteel (Satin & Mirror Finished).
Case Geometry, Dial Execution & Bracelet Fit
From the font weight on the dial transfer printing to the micro-engraved clasp interior, every component is built to 1:1 tolerances. The sapphire crystal sits flush with the bezel ring and features internal anti-reflective treatment for zero-glare viewing.
