The newly unveiled Blancpain Fifty Fathoms Tech 45mm blends serious diving capabilities with refined design updates. With a lightweight titanium case, a robust 5-day movement, and a quick-change strap system, this is the most purpose-driven Fifty Fathoms yet.
Blancpain Fifty Fathoms: From Combat Roots to Modern Precision
Founded in 1735, Blancpain is the oldest watchmaking brand still in operation today. The Fifty Fathoms, introduced in 1953, was one of the first true dive watches ever made, designed for combat swimmers and later worn by ocean explorers. Over the decades, the collection has evolved while preserving its tool-watch DNA. The Tech series now takes that legacy into a new technical chapter, pushing boundaries in design, materials, and usability.
Built for Depth, Engineered for Control
This new reference features a 45mm Grade 23 titanium case, measuring 14.1mm thick and rated to 300 meters of water resistance. A helium escape valve ensures safety for saturation diving. Inside, the automatic calibre 1315A delivers a solid 120-hour power reserve, enhanced by a silicon balance spring for superior resistance to magnetism. The “absolute black” dial absorbs 97% of ambient light, maximizing contrast in dark underwater conditions. Blancpain also introduces a quick-release strap system, a first for the Fifty Fathoms line, allowing tool-free changes between the included black, white, and orange rubber straps.
Who the Blancpain Tech 45mm Is Really Made For
This is a watch built for serious divers, but also for those who appreciate technical design in everyday life. The use of lightweight titanium and the addition of interchangeable straps make it surprisingly wearable, while its clear, high-contrast display speaks to its functional core. Aesthetic touches like the bold markers, clean dial layout, and ceramic bezel insert nod to the collection’s heritage, but with a sharp, modern attitude. It’s a Fifty Fathoms made not for display cases—but for action.
A Purpose-Built Evolution
With the Fifty Fathoms Tech 45mm, Blancpain expands its permanent collection with a model that’s less about nostalgia and more about engineering. It doesn’t rely on vintage cues or gimmicks—it simply does the job, and does it well. Priced at $22,700 USD, this reference is available now worldwide, positioned as a permanent, non-limited model.
This is the kind of watch that reminds you Blancpain isn’t just preserving history—it’s still building serious tools for the ocean. A modern diver’s companion, no compromise required…which reminds us of another piece from Blanpain : the Fifty Fathoms 38mm.
