U-Boat Darkmoon 25° SS Black

Marking 25 years of U-Boat’s bold watchmaking, this Darkmoon 25° model wears a black painted metal dial amplified by the collection’s oil-bath immersion technique, producing a glass-free, three-dimensional look, with an ‘Anniversary’ plaque and 25th-anniversary logo at 6 o’clock. The 46.5mm AISI 316L stainless steel case retains U-Boat’s distinctive left-side crown protector beneath a domed sapphire crystal. The Swiss Ronda 762 quartz movement is itself lubricated in an oil bath, and the caseback uses an innovative locking-ring system for quick battery replacement. The watch is completed with an ultra-resistant black vulcanised rubber strap and is rated to 50 metres of water resistance. Limited to 300 pieces worldwide.
