Evolution of the Flightdeck model, the 50 mm case, in 18 carats yellow gold, received “martellée” finishing, and then it has been partially drilled, in order to create thin fissures. All these small cracks have been patiently filled with black diamonds. On the side of the case black diamonds have been also set to reproduce the U-BOAT logo.
The watch boasts a black diamond studded on the chrono pusher, a see-through back of the case with a gold rotor. Last but not least a U-Boat Vintage strap, in hand made and hand finished calf leather.
