Blancpain Fifty Fathoms Tech 45: A Bold New Era for the Iconic Diver

Blancpain continues to evolve its legendary Fifty Fathoms collection with the introduction of the Fifty Fathoms Tech 45. Joining the permanent collection, this new iteration blends professional-grade dive performance with vibrant, lifestyle-driven aesthetics—making it one of the most versatile and modern tool watches from the brand to date.

A Modern Take on a Classic Tool Watch

The Fifty Fathoms Tech 45 builds upon the success of previous Tech models, including the Tech Gombessa (2023) and the Tech BOC – Blancpain Ocean Commitment (2025). As Blancpain President & CEO Marc A. Hayek explains, “When we developed the Fifty Fathoms Tech Gombessa in 2023, it came from the question: If the Fifty Fathoms was invented today, what would it look like? Now, we’ve brought color and style into the Tech line, proving that a serious diver’s watch can also have a lifestyle side.”

The result? A bold timepiece that retains its professional diving pedigree while embracing modern design.

Technical Excellence in Titanium

Crafted from Grade 23 titanium, the Tech 45 features a 45mm x 14.1mm case designed for extreme conditions. Its spherical AR-coated sapphire crystal, unidirectional bezel with a black ceramic inlay, and 300-meter water resistance cement its status as a true diver’s instrument. A helium escape valve ensures safety for saturation diving, while the sapphire display back offers a glimpse of the high-performance movement.

High-Performance Movement

Inside beats the in-house Blancpain caliber 1315A, a Swiss automatic movement with:

• 35 jewels

• 28,800 vph

• 120-hour (5-day) power reserve

Functions include hours, minutes, central seconds, and date—delivering reliable performance even under extreme conditions.

A Fresh Splash of Color

For the first time, the Tech line offers interchangeable rubber straps in classic black, vivid white, and vivid orange—adding a bold, lifestyle-oriented twist to the professional diver. The absolute black dial, which absorbs up to 97% of light, contrasts strikingly with Super-Luminova hands and block-shaped appliques. An orange central seconds hand adds another pop of color, enhancing legibility and visual appeal.

This latest addition to the Fifty Fathoms Tech line proves that a professional diver’s watch can be both rugged and stylish. Whether you’re exploring the ocean depths or making a statement on land, the Tech 45 delivers precision, performance, and personality.
