The Blancpain Fifty Fathoms Bathyscaphe Mokarran (Ref. 5005-0153-NABA) is more than just a dive watch — it is a tribute to the beauty and fragility of the ocean, and a celebration of Blancpain’s dedication to marine conservation. Limited to just 50 pieces worldwide, this striking timepiece was created in honor of the elusive great hammerhead shark (Sphyrna mokarran), a majestic creature that inspired both its design and its mission. With this special edition, Blancpain merges exceptional Swiss watchmaking with purposeful environmental advocacy. Housed in a 45mm satin-brushed black ceramic case, the Bathyscaphe Mokarran boasts a bold yet refined presence on the wrist. The deep green sunburst dial is both vivid and mysterious — evoking the shifting tones of the ocean — while maintaining exceptional legibility through Super-LumiNova®-filled indexes and hands. The unidirectional ceramic bezel, also in black with a brushed finish, enhances its diving utility while adding to the watch’s sleek and modern aesthetic. Inside, the timepiece is powered by the highly respected Caliber 1315 movement — a self-winding mechanical powerhouse with an impressive 5-day (120-hour) power reserve and excellent shock resistance, designed for high-performance and reliability under pressure. In true Blancpain spirit, the Bathyscaphe Mokarran Limited Edition is not only a precision instrument rated for 300 meters of water resistance, but also a symbol of the brand's environmental mission. A portion of the proceeds from each watch directly supports Blancpain’s Ocean Commitment — specifically funding research and conservation efforts to protect hammerhead sharks in French Polynesia. On the sapphire caseback, a finely detailed engraving of the great hammerhead shark adds a final, meaningful touch to this rare collector’s piece. The Fifty Fathoms Bathyscaphe Mokarran is a watch for those who not only appreciate elite horology, but also feel a deeper connection to the sea. With its bold design, technical excellence, and genuine commitment to marine preservation, this timepiece stands as a powerful statement — of style, purpose, and passion for the oceans.
