The Blancpain Fifty Fathoms Tech BOC IV is a stunning evolution of the Fifty Fathoms line, combining underwater performance with refined design. This latest model features a 45mm grade 23 titanium case, offering a lightweight feel and excellent durability. It also has 300-meter water resistance and a helium escape valve—a unique addition to the Fifty Fathoms series.


Blancpain’s “Absolute Black” dial, designed to absorb 97% of light, enhances visibility in deep waters. The blue accents on the seconds hand and ‘Tech’ text add a subtle yet distinctive touch. The unidirectional diving bezel with a domed ceramic insert provides tactile satisfaction, offering a smooth yet assertive click with each turn.
The watch is powered by the in-house Caliber 1315A movement, boasting a five-day power reserve and a minimalist 18-ct gold rotor with the Blancpain Ocean Commitment (BOC) logo. This model is not only a technical marvel but also a force for good, as €1,000 from each sale supports the Sulubaaï Marine Research Center in the Philippines, contributing to restoring and protecting Shark Fin Bay’s rich biodiversity.
Limited to just 50 pieces, the Blancpain Fifty Fathoms Tech BOC IV is available for $25,000, making it a must-have for serious divers and watch collectors who value luxury and conservation.
