Like its 2013 predecessors (which did include a 38-mm model, albeit only in a white dial/white strap combo), the new Bathyscaphe pays considerable aesthetic tribute to its 1950s-era ancestor, with vintage-style hands, sharply defined case contours, and a luminescent dot on its notched, unidirectional bezel as a reference for divers. The bezel, in satin-brushed stainless steel, has a blue ceramic insert with numerals and indices in Liquidmetal, an alloy known for its deformation resistance and long term stability, which has been used in recent years by Blancpain and several of its other sister brands within the Swatch Group. The Abyss blue dial has a sunburst finish and a small date window at 4:30.
Inside the 300-meter water-resistant case, and on display through a sapphire caseback window, is Blancpain’s self-winding Caliber 1150. Its notable features include two series-coupled barrels, which store an impressive 100-hour power reserve while guaranteeing a constant flow of energy; and a silicon balance spring, whose technical advantages include lower density (and thus reduced weight), increased shock resistance, and imperviousness to magnetic fields — all factors that increase the movements’s chronometric performance. The watch’s price will be announced at Baselworld 2017.
