The new  U-Boat Darkmoon SS watch 8465/B  has a stainless steel case with a diameter of 44 mm. The watch contains a quartz movement that is completely submerged in an oil bath. The oily liquid that surrounds the dial transforms it into an absolute black, making it three-dimensional and deep. This liquid creates a continuously moving compensation bubble on the dial. The new U-Boat series features a curved red sapphire crystal, screw-down crown, luminescent hands and indexes, vulcanized rubber strap with U-Boat raised logos and the name of the collection, is 5 ATM water resistant and comes with a 2 year worldwide warranty. .
