Blancpain’s legacy in the world of dive watches is unparalleled, with the Fifty Fathoms series standing as a testament to the brand’s dedication to underwater exploration. The latest addition, the Fifty Fathoms Tech BOC IV, not only showcases Blancpain’s horological prowess but also underscores its commitment to ocean conservation through the Blancpain Ocean Commitment (BOC) initiative.
A Brief History of Blancpain and the Fifty Fathoms Series
Founded in 1735, Blancpain is one of the world’s oldest watchmaking brands, known for its dedication to mechanical innovation and traditional craftsmanship. Unlike many Swiss watchmakers, Blancpain has never produced a quartz watch, remaining committed to mechanical movements.
The Fifty Fathoms was born in 1953, when French Navy combat divers—led by Captain Robert “Bob” Maloubier and Lieutenant Claude Riffaud—needed a reliable underwater timing instrument. Blancpain, under the leadership of CEO Jean-Jacques Fiechter, answered the call, creating the first-ever modern dive watch. It featured a unidirectional rotating bezel, a highly legible dial, and water resistance up to 50 fathoms (91 meters), a groundbreaking feat at the time.
Since then, the Fifty Fathoms series has evolved with technological advancements, continuously setting the standard for professional dive watches while maintaining a strong connection to ocean conservation.
Design and Build: Merging Form with Function
The Fifty Fathoms Tech BOC IV is a harmonious blend of robust engineering and sleek aesthetics:
• Case Dimensions: Measuring at 45 mm in diameter and 14.1 mm in thickness, this timepiece strikes a balance between substantial presence and wearable comfort.
• Material: Crafted from Grade 23 titanium, renowned for its exceptional strength-to-weight ratio, the watch ensures durability without compromising on lightness.
• Bezel: The unidirectional bezel features a domed black ceramic insert angled towards the dial, facilitating ease of use even with diving gloves.
• Dial: The “absolute black” dial absorbs up to 97% of light, ensuring optimal readability. Luminescent block-shaped appliques serve as hour markers, enhancing visibility in low-light conditions.
• Strap: An integrated black rubber strap, attached via central lugs from inside the case, offers both ergonomic comfort and a contemporary aesthetic.

At its core, the Fifty Fathoms Tech BOC IV is designed to meet the rigorous demands of professional diving:
• Water Resistance: Rated to withstand pressures up to 30 bar (approximately 300 meters), making it suitable for deep-sea adventures.
• Helium Valve: Equipped with a helium escape valve, the watch is adept for saturation dives in hyperbaric chambers, ensuring reliability during prolonged underwater missions.
• Movement: Powered by the calibre 1315A, an automatic movement renowned for its precision and robustness. It boasts a five-day power reserve and features an anti-magnetic silicon balance spring, ensuring consistent performance.
• Oscillating Weight: The 18 ct gold oscillating weight, adorned with the blue BOC logo, is visible through the sapphire case back, showcasing the meticulous craftsmanship.
A Commitment to Ocean Conservation
Beyond its technical excellence, the Fifty Fathoms Tech BOC IV plays a pivotal role in supporting marine preservation:
• Limited Edition: This model is limited to 100 pieces, emphasizing its exclusivity and the brand’s dedication to meaningful contributions.
• Funding Conservation: For each watch sold, €1,000 is allocated to the Blancpain x Sulubaaï Marine Research Center, culminating in a total fund of €100,000. This initiative supports sustainable marine resource management around Pangatalan Island and Shark Fin Bay in Palawan, Philippines.
• Sea Academy Programme: Since 2020, Blancpain has supported the Sea Academy programme by the Sulubaaï Environmental Foundation. This initiative focuses on creating a network of marine protected areas (MPAs) in partnership with local communities, emphasizing protection, restoration, education, and replication.
