Case & Dial

Heritage Aesthetics,
Modern Precision

The 41mm steel case houses a domed, anti-reflective sapphire crystal. The black dial features applied indices and a fluted winding crown — a nod to the earliest TUDOR diving watches of the 1950s. The bi-compax layout positions the 30-minute totalizer at 3 o'clock and the running seconds at 9 o'clock.

Brushed and polished steel surfaces
Screw-down winding crown

Bidirectional rotating bezel with matte black ceramic insert
