Blancpain Fifty Fathoms 50021-12B30-52B Description

The Blancpain Fifty Fathoms 70th Anniversary “Tech Gombessa” Act 2, released in 2023, is a significant technical evolution of the dive watch. Developed for long-duration technical diving, its key innovation is a patented three-hour dive timer complication, featuring a special hand that circles the dial once every three hours, linked to a three-hour graduated bezel. The 47mm case is made from lightweight Grade 23 titanium and features a central lug design for an ergonomic fit. It is powered by the Caliber 13P8, with a 120-hour power reserve. This reference is a purpose-built professional instrument that advances the functionality of the mechanical dive watch for the modern era of exploration.
