Blancpain x Swatch Bioceramic Scuba Fifty Fathoms ‘Green Abyss’: An Informative Overview

In June 2025, Swatch announced a new addition to its collaborative series with Blancpain: the Scuba Fifty Fathoms ‘Green Abyss’. This model follows the design language and technical innovations seen in prior releases while introducing a bold new colorway. The watch will be available from June 7, 2025, exclusively at Swatch boutiques, and is priced at $400.

Background of the Collaboration

The Blancpain x Swatch collaboration began in 2023 and gained significant attention for merging Swatch’s accessible pricing and experimental materials with Blancpain’s heritage in dive watches. The series is inspired by the iconic Blancpain Fifty Fathoms, which is widely regarded as one of the first modern dive watches. This collaboration preserves many design characteristics of the original while utilizing Swatch’s proprietary Bioceramic material.

Design and Aesthetic

The ‘Green Abyss’ version brings a forest green Bioceramic case measuring 42.3mm in diameter and 14.4mm in thickness. Bioceramic, a sustainable blend of ceramic and bio-sourced plastic, offers a durable yet lightweight experience. The unidirectional bezel is also crafted from green Bioceramic, featuring a black resin insert enhanced with Super-LumiNova for visibility in low-light conditions.

The dial is complemented by cream-colored Super-LumiNova on the hour markers and hands, creating a subtle contrast that enhances legibility. The result is a watch that balances modern materials with vintage aesthetics.

Technical Specifications

The case is made from Bioceramic, with a diameter of 42.3mm and a thickness of 14.4mm. It features a unidirectional bezel made from green Bioceramic and a black resin insert filled with Super-LumiNova. The dial is forest green with cream Super-LumiNova accents. The watch offers a water resistance of 91 meters, equivalent to fifty fathoms, and is paired with a NATO-style fabric strap.

Movement

The watch is powered by the Swatch Sistem51 automatic movement. Introduced in 2013, Sistem51 is notable for being entirely machine-assembled and comprising only 51 parts. It features automatic winding, a 90-hour power reserve, a frequency of 21,600 vibrations per hour (VPH), and displays hours, minutes, seconds, and date. This movement supports the collaboration’s commitment to mechanical timekeeping, adhering to Blancpain’s historical avoidance of quartz movements.

Color Variants in the Series

The ‘Green Abyss’ joins a family of previously released color variants under the Scuba Fifty Fathoms line. These include the Atlantic Ocean in deep blue, the Pacific Ocean in bright yellow, the Indian Ocean in lighter green with orange accents, the Arctic Ocean in white, and the Antarctic Ocean in beige. These watches reflect the diversity of marine ecosystems and are designed with aesthetic themes representing each named ocean.

Availability and Distribution

The ‘Green Abyss’ will not be a limited edition and will be distributed through Swatch boutiques. As with previous releases, the availability may vary depending on regional demand and supply logistics. Online sales are limited to select markets; therefore, in-store purchases remain the primary channel for acquisition.

Usage and Practicality

The combination of 91 meters of water resistance, luminous markers, and a unidirectional bezel makes the Scuba Fifty Fathoms ‘Green Abyss’ a functional tool for recreational diving. The NATO strap provides comfort and breathability, especially suited for warm weather and water-based activities. Its durable Bioceramic case ensures resistance to corrosion and scratches, making it a reliable companion for both urban and outdoor settings.

Heritage and Legacy

The Fifty Fathoms line was first introduced by Blancpain in 1953 as a professional dive watch for French Navy combat divers. It pioneered key features now considered standard in dive watches, including water resistance, a rotating bezel, and luminous markings. The Swatch collaboration maintains these legacy traits while making the timepiece accessible to a broader demographic through affordable pricing and modern materials.

Market Position

Positioned at $400, the Scuba Fifty Fathoms ‘Green Abyss’ occupies a unique space between entry-level mechanical watches and luxury divers. It appeals to both new collectors and seasoned enthusiasts seeking an affordable yet mechanically sound dive watch with historical significance. The use of the SISTEM51 movement and Bioceramic materials also aligns with a growing market interest in sustainability and innovative production methods.

Technical Summary

The Blancpain x Swatch Scuba Fifty Fathoms ‘Green Abyss’ carries the reference number SO35G100. It features a 42.3mm Bioceramic case, a thickness of 14.4mm, and includes a NATO-style strap. The movement is an automatic Sistem51 with a 90-hour power reserve. The watch includes Super-LumiNova for visibility, supports hours, minutes, seconds, and date functions, and has a water resistance rating of 91 meters. It will be available through Swatch boutiques for $400.

Conclusion

The Blancpain x Swatch Bioceramic Scuba Fifty Fathoms ‘Green Abyss’ is a noteworthy addition to a widely celebrated collaborative series. Its combination of sustainable materials, mechanical reliability, and accessible pricing solidifies its position as a functional and collectible dive watch. This model continues to uphold the legacy of the original Fifty Fathoms while appealing to contemporary preferences in design, color, and material.
