U-Boat Automatic Watches

Limited Edition of 999 Pieces The case, in titanium grade 5, measures 53mm x 18mm (65mm with crown). The crystal is sapphire and it is water resistant to 300 meters. The bi-directional rotating bezel is lockable with a lever on the right side of the case. The U-42's winding crown was built in two parts: one is attached to the movement stem whilst the other is hinged to it with a pivot. This gives a flexible joint configuration which allows the crown to protrude considerably from the watch itself for winding and setting, yet returning it to a protected, hidden position diminishing the side clutter when in action. Movement is the automatic Swiss caliber U-BOAT U-28 with 25 jewels, 28,800 vph and a power reserve of 40 hours. The dial is made with a slab in brass galvanized and finished with a bright enamel paste. Hands are German Silver. The leather strap measures 23mm with 23mm buckle.

Limited Edition of 100 Pieces The case, in stainless steel, measures 51mm x 19mm. It has a sapphire crystal and is water resistant to 120 meters. Movement is an automatic Swiss split-seconds chronograph caliber by Alfred Rochat (base Valjoux 7750) with 25 jewels, 28,800 vph and a power reserve of 44 hours.
