At its heart beats the sophisticated in-house Calibre 1315, a self-winding movement offering an impressive 120-hour power reserve through three series-coupled barrels. The movement features a silicon balance spring, ensuring exceptional accuracy and magnetic resistance. Through the sapphire crystal case back, admirers can appreciate the NAC-coated 18K gold oscillating weight and haute horlogerie finishing.

The unidirectional rotating bezel, a hallmark of professional diving watches, features a black ceramic insert with precise LiquidMetal™ hour markers. Water-resistant to 300 meters, this modern interpretation of the iconic Bathyscaphe is secured by a black ceramic bracelet, featuring Blancpain’s patented link assembly system developed over three years for optimal comfort and durability.
