The latest and updated U-Boat Darkmoon 40 MM Black IP Bronze Watch 9304 has an AISI 316L stainless steel IP Bronze treatment case with a 40 mm diameter. The watch contains a Ronda quartz movement. The case is completely filled with a special oil that highlights the dial, creating an optical effect of a more intense color and better legibility. This fluid creates a continuously moving compensation bubble on the dial. The new series from U-Boat has a spherical sapphire glass, a screw-down crown, luminous hands and indexes, a leather strap, is 5 ATM waterproof and has a 2-year worldwide warranty.
The movement and back cover have been renewed, making battery replacement easier.
