Most dive watches never see water deeper than a hotel pool. But UNIMATIC's ProDiver is built for open-water adventures. Rated and individually tested to 2,000 feet, the Thistlegorm is a warm-up and the walls of the Great Blue Hole are well within reach. The 40mm brushed 316L stainless steel case houses a 120-click mono-directional ceramic bezel loaded with Super-LumiNova BGW09 markers, ladder phantom hands in dual-lume white and orange, a reverse lollipop seconds hand, and a date window at six. Power comes from a Swiss Sellita SW200-1 automatic beating at 28,800 bph with 41 hours of reserve, protected by a 3mm double-domed sapphire crystal with anti-reflective coating. Each bundle includes a brushed solid steel bracelet and a color-matched quick-release TPU strap. Available in matte black or reflex blue. Made in Italy, limited to 300 individually numbered pieces each.
