Blancpain Fifty Fathoms Tech Ref. 5029: A New Permanent Collection Diver with Quick-Release Strap System
Blancpain Expands the Fifty Fathoms Tech Line with Standard-Production Model
Blancpain has officially expanded its Fifty Fathoms Tech sub-collection by introducing the Reference 5029, a new standard-production dive watch that builds upon the success of the limited-edition Ocean Commitment IV model released earlier in 2025. This latest addition brings the brand's most modern diver into the permanent catalog, making it more accessible to collectors who desire a thoroughly contemporary Blancpain dive watch.
A Purpose-Built Modern Diver
Following the debut of the Fifty Fathoms Tech Gombessa in 2023 — a highly specialized model developed with underwater explorer Laurent Ballesta — and the limited-edition Ocean Commitment IV, the Ref. 5029 marks the Tech line's evolution into a core offering. While the original Fifty Fathoms remains a sacrosanct heritage design, the Tech series allows Blancpain to push the boundaries of its iconic diver without compromising the classic platform.
Key Specifications and Design
Crafted from Grade 23 titanium with predominantly brushed surfaces, the case measures 45mm in diameter by 14.2mm thick. The Tech series features a distinctive single central lug design that forms an integrated structure with the rubber strap, forgoing traditional lugs entirely. A screw-down crown and helium escape valve furnish the sides, with water resistance rated at 300 meters.
The most notable innovation is the new quick-release strap system. The centrally-mounted lugs allow owners to disconnect the strap by pressing two buttons on the underside of the case — a first for the Tech series. Blancpain includes two rubber straps with each watch, available in orange, black, or white, all finished with chunky titanium tang buckles.

Movement and Dial Details
Inside, the Ref. 5029 houses the in-house Caliber 1315A, composed of 227 individual components with a silicon hairspring. The 35-jewel automatic movement runs at 28,800vph (4 Hz) and delivers an impressive 120-hour power reserve via a three-barrel design. Unlike the Gombessa's specialized fourth hand, the 1315A offers standard three-handed time-and-date functionality, making this a more versatile daily wearer.
The dial features Blancpain's proprietary "Absolute Black" finish, which absorbs up to 97% of incoming light to maximize legibility. Applied hour markers are crafted from solid blocks of luminous material, and bright orange accents on the seconds hand and "Tech" branding distinguish this model from its blue-accented Ocean Commitment sibling.
How It Compares
At $22,700 USD, the Ref. 5029 is slightly less expensive than the limited-edition Ocean Commitment IV despite including the additional quick-release mechanism. The price positions it above the standard Fifty Fathoms Automatique 5010 ($18,400) but below the more specialized Gombessa model, offering a middle ground for those seeking modern dive watch technology.
Frequently Asked Questions
Q: Is the Fifty Fathoms Tech Ref. 5029 a limited edition?
A: No, the Ref. 5029 is a standard-production model joining Blancpain's permanent collection, unlike the preceding Ocean Commitment IV which was limited to 100 pieces.
Q: What makes the three-hour bezel different from a standard dive bezel?
A: The Tech series' patented three-hour bezel is designed for technical and rebreather diving, where extended bottom times of several hours are common. The dedicated hand completes a full rotation every 3 hours, allowing divers to track extended dive times beyond the standard 60-minute bezel range.
Q: Can additional straps be purchased separately?
A: Yes, Blancpain offers optional rubber straps in white, black, and orange that are compatible with the quick-release system.
