The latest limited edition dive watch from Blancpain contributes to marine conservation efforts by supporting a new research center in the Philippines.
Blancpain has introduced the Fifty Fathoms Tech Ocean Commitment IV, a timepiece that reflects its ongoing dedication to ocean preservation. This new model plays a role in financing a marine research facility in Shark Fin Bay, Palawan, through proceeds from its sales. The launch of this watch aligns with Blancpain’s longstanding Ocean Commitment program, which has supported various environmental initiatives since 2020.
Pangatalan Island, a small yet ecologically significant area in the Sulu Sea, serves as a focal point in this story. Once damaged by unsustainable fishing practices, including the destruction of mangroves and coral reefs, the island has undergone extensive restoration. Conservationist Frédéric Tardieu, founder of the Sulubaaï Environmental Foundation, has led efforts to rehabilitate the island’s ecosystems. Through marine protected areas and aquaculture projects, the foundation has contributed to the revival of local marine life, including coral reefs and fish populations.
Blancpain’s involvement in this initiative extends beyond financial support. The brand has helped fund the construction of a marine research center designed to facilitate scientific studies and conservation activities. This research facility will serve as a base for marine biologists and students conducting fieldwork in Shark Fin Bay, an area rich in biodiversity but historically affected by harmful fishing techniques.
The Fifty Fathoms Tech Ocean Commitment IV is not merely a reissue of a previous model. It incorporates advancements in design and functionality, ensuring it meets the demands of modern divers. The watch features a 45mm grade 23 titanium case, an integrated rubber strap, and an “absolute black” dial that absorbs 97% of available light. Additionally, it is equipped with a helium release valve and a domed ceramic bezel. Powering the timepiece is the Blancpain manufacture calibre 1315A, providing a 120-hour power reserve and incorporating an anti-magnetic silicon escapement.
Distinctive blue accents on the seconds hand and dial text, along with the Ocean Commitment logo on the winding rotor, set this edition apart. With only 100 units available, the watch represents both exclusivity and a tangible contribution to ocean conservation efforts. Blancpain ambassador Laurent Ballesta has played a key role in showcasing the watch’s capabilities, having previously captured award-winning underwater photography in the region.
Shark Fin Bay, located on the eastern coast of Palawan, is home to several fishing communities and diverse marine habitats. While tourism has yet to significantly impact this area, destructive fishing methods had previously damaged the marine environment. Over the past decade, however, conservation initiatives have facilitated the establishment of marine protected areas, allowing the ecosystem to recover. The new research center will further support these efforts by providing a dedicated space for scientific studies and sustainable marine management.
A recent dive in a newly designated marine protected area near Pangatalan highlighted the positive effects of conservation work. The waters were clear, and marine life, including lobsters, lionfish, turtles, and clownfish, thrived within the reef. The site, protected from human exploitation, demonstrated the resilience of underwater ecosystems when given the opportunity to regenerate.
In terms of performance, the Fifty Fathoms Tech Ocean Commitment IV builds upon the success of the Fifty Fathoms Tech Gombessa, a model launched in 2023. While the Gombessa was designed with a specialized three-hour elapsed time function for rebreather diving, the BOC IV adopts a more conventional one-hour elapsed time bezel. The 45mm case diameter, slightly smaller than the Gombessa’s 47mm, contributes to a balanced wrist presence. The rubber strap, secured with hex bolts, ensures durability, though its proprietary design limits aftermarket strap options. Blancpain has, however, provided an extended strap option for those requiring additional length over dive suits.
Despite the inclusion of a helium release valve, a feature primarily used in saturation diving environments, the BOC IV remains a highly functional dive watch suitable for recreational and professional use. The calibre 1315A movement, visible through the sapphire caseback, offers robust performance with a high level of finishing. Its 120-hour power reserve and resistance to magnetism align with Blancpain’s emphasis on precision and durability.
Blancpain’s Ocean Commitment program stands out among watch industry environmental initiatives. Unlike superficial marketing campaigns, this program directly funds conservation projects with measurable results. The establishment of the marine research center in Palawan exemplifies the brand’s commitment to making a lasting impact.
The official opening of the research facility was attended by regional leaders, representatives from the Sulubaaï Foundation, and Blancpain executives. The center, equipped with laboratories, classrooms, and accommodation for researchers, will support ongoing conservation work in Shark Fin Bay. Funding from the sale of the Fifty Fathoms Tech Ocean Commitment IV ensures the sustainability of this initiative.
The Fifty Fathoms collection has long been associated with pioneering dive watch technology, and this latest addition reinforces that legacy. The combination of innovative materials, practical design, and environmental advocacy makes the Fifty Fathoms Tech Ocean Commitment IV a notable release within the watch industry. By acquiring one of these limited edition timepieces, collectors and enthusiasts contribute directly to marine conservation efforts.
