Craftsmanship & Technical Specifications
Atelier Description & Craftsmanship
Built on Clean / VS Factory‘s dedicated assembly line, the Rolex GMT Masters II 126710BLNR Batgirl Cal.3285 brings together Solid 904L Oystersteel (Satin & Mirror Finished) metallurgy (40MM × 12.1mm (Bi-directional 24-Hour Bezel)) and the 28,800 vph Dandong DD3285 True GMT with Independent Hour Hand (70-Hour Reserve (28,800 vph)). Every curve of the lug profile and crown guard has been laser-scanned from the original reference.
Case Geometry, Dial Execution & Bracelet Fit
Inside the clasp, the locking mechanism engages cleanly without rattle or sharp burrs. Above the dial, a Mohs-9 synthetic sapphire crystal with anti-reflective coating protects the hands and markers from everyday scuffs.
