# Three-Hour Dive Watches The Fifty Fathoms Tech Introduces Blancpain’s Patented Three-Hour Bezel By Amy Duong | Published 2026-06-10 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/fifty-fathoms-tech References: [blancpain](http://blancpain.com/en)  The Fifty Fathoms Tech is the latest dive watch from Blancpain, unveiled on World Oceans Day as part of the brand’s ongoing [Blancpain Ocean](https://www.trendhunter.com/trends/blancpain-fifty-fathoms-automatique) Commitment initiative. Inspired by the original Fifty Fathoms introduced in 1953, the new model is housed in a 47 mm Grade 23 [titanium case](https://www.trendhunter.com/trends/summerready-deepwater-watch) and is water resistant to 300 meters. The watch features an absolute black dial designed to absorb up to 97 percent of ambient light, paired with two-tone [Super-LumiNova](https://www.trendhunter.com/trends/br03-diver) that uses blue illumination for diving indications and green illumination for enhanced readability underwater. The watch’s defining feature is a patented three-hour bezel combined with a dedicated three-hour hand, adapting traditional GMT-style functionality for extended dive timing. Power comes from Blancpain’s Calibre 13P5A movement, which delivers a 120-hour power reserve and is derived from the brand’s Calibre 1315 architecture. Additional features include a tool-free interchangeable strap system with orange, black, and white rubber strap options.
