U-Boat - The Unicum

Transformations for the U-Boat U-42 B&B model, which thanks to a series of special treatments becomes The Unicum. Made in a vintage style, its titanium case has undergone a black IP treatment, with bronze details. The case and bezel have been treated with special acids to enhance the vintage look and make each model different. The dial is composed of two superimposed discs, one black and one bronze; the hands were first painted, then specially bleached and then scratched by hand to enhance the ageing effect. The leather straps are made and sewn by Tuscan craftsmen.
