U-Boat Darkmoon 25° SS Blue Soleil

This Darkmoon 25° edition, released for U-Boat’s 25th anniversary, presents a blue painted metal dial with a brushed soleil finish, its colour deepened by the collection’s oil-bath immersion technique for a striking glass-free, three-dimensional effect, along with an ‘Anniversary’ plaque at 6 o’clock. The 46.5mm AISI 316L stainless steel case carries the brand’s distinctive left-side crown protector and is topped with a domed sapphire crystal. A Swiss Ronda 762 quartz movement, itself lubricated in an oil bath, powers the watch through a caseback with an innovative locking-ring system for quick battery access. It is fitted on an ultra-resistant black vulcanised rubber strap and rated to 50 metres of water resistance. Limited to 300 pieces worldwide.
