Montblanc Iced Sea 0 Oxygen: A Rock-Washed Dive Watch with Glacier-Pattern Flair

Montblanc’s Iced Sea Automatic Date 0 Oxygen (ref. MB137541) introduces the 0 Oxygen concept—a truly oxygen-free case that prevents condensation and oxidation—paired with a rock-washed finish achieved by tumbling the case and bracelet with Mont Blanc stones to produce a rugged, glacier-inspired look. The 41mm steel diver is rated to 300m, uses the MB 24.17 (SW200-based) movement at 28,800vph with a 38-hour power reserve, and features a glacier-pattern dial with Super-LumiNova hands, a laser-engraved case back, and a quick-release bracelet system. Priced at €5,300 / US$5,600 / £4,600, the piece is praised for its distinctive distressed aesthetic and comfortable wear, though the reviewer questions the modest 38-hour power reserve and hopes for possible future movement upgrades.
