he Fifty Fathoms Tech 45 mm debuts in the permanent collection, with a new interchangeable strap system, expanding its technical repertoire with bold rubber options in classic black, white or vivid orange. These vibrant colors inject a fresh, lifestyle-driven twist into the iconic diver’s instrument, while preserving all its exceptional tool-watch features.

“When we developed the Fifty Fathoms Tech Gombessa in 2023, it came from the question I asked myself: If the Fifty Fathoms was invented today, what would it look like?” says Marc A. Hayek, President & CEO of Blancpain. - “Then, in 2025, came the Fifty Fathoms Tech BOC (Blancpain Ocean Commitment), making that modern technology more wearable. Now, I love that we can bring color and style into the Tech line, proving that a serious diver’s watch can also have a lifestyle side.”

Blancpain’s enduring connection to the Ocean and pioneering spirit runs deep. While firmly rooted in the Maison’s professional diving heritage and unmatched legacy in professional diving timepieces, the new Fifty Fathoms Tech emerges as a thoroughly modern expression of Blancpain’s most famous collection, blending technicity with a new, unexpected dose of style.

Originally conceived as a serious tool watch and diving instrument, the Fifty Fathoms has long been the choice of professional divers, explorers, and underwater photographers. The Tech variant, housed in Grade 23 brushed titanium, embodies that legacy with a bold 45 mm case diameter, a helium escape valve, and a unidirectional 120-click ceramic bezel optimized for use with gloved hands. Its absolute black dial absorbs up to 97% of light – an impressive feat ensuring maximum legibility in murky depths or low-light conditions, while creating a striking contrast with the luminescent block-shaped appliques.

Yet Blancpain’s latest chapter writes a new narrative: the tool watch is going lifestyle. In a significant update for 2025, the Fifty Fathoms Tech introduces a fully interchangeable strap system, empowering wearers to switch styles in seconds, no tools required. Additionally, Blancpain offers straps in multiple lengths, a crucial detail for divers who may wear the watch over a wetsuit, while also making it perfect for everyday wear on a bare wrist.

Color, too, is making waves. Beyond classic black rubber, Blancpain is releasing two new summer-ready hues: a crisp white and a vibrant orange. The latter isn’t just an aesthetic flourish; it matches the Tech’s orange central seconds hand and TECH inscription on the dial, proving that even the most serious diving instruments can embrace personality and fun.

Of course, the Fifty Fathoms Tech retains its mechanical credentials. Powering the watch is the automatic calibre 1315A, a 4 Hz movement widely respected among collectors for its robust 120-hour power reserve, precision timekeeping, and beautifully finished architecture.

The sapphire case-back offers a view of the movement’s decorations, underscoring Blancpain’s dedication to Haute Horlogerie even in the Maison’s most utilitarian creations.

In short, the Fifty Fathoms Tech bridges worlds: as capable in the abyss as it is on dry land. It’s a pure diver’s tool, reborn as a polyvalent companion for any occasion – from exploring coral reefs to strolling through a summer cityscape or making a statement far above sea level.
