The Blancpain Fifty Fathoms Bathyscaphe Ref. 5100B-1110-B52A is a refined expression of Blancpain’s legendary diving legacy, engineered for both elegance and endurance. Presented in a compact 38mm satin-brushed stainless steel case, this timepiece offers a contemporary yet timeless profile, suited for discerning collectors and active lifestyles alike. Its unidirectional bezel, featuring a scratch-resistant ceramic insert with Liquidmetal™ hour markers, ensures reliable dive timing while maintaining a sleek and durable finish. The watch is powered by Blancpain’s ultra-thin Caliber 1150, an automatic movement renowned for its high efficiency and technical refinement. Offering a remarkable 100-hour power reserve thanks to twin barrels, this movement operates at 21,600 vibrations per hour and incorporates a silicon balance spring for superior anti-magnetic and thermal stability. Its hand-finished components, visible through a sapphire exhibition caseback, speak to the meticulous craftsmanship and precision that define the maison’s approach to watchmaking. The Dial is rendered in a distinguished grey meteor tone, its sunburst finish subtly shifting under different lighting conditions to evoke the depths of the ocean. Luminous baton-style hands and block hour markers provide exceptional legibility, essential for underwater use. This minimalist design is further enhanced by the absence of a date window, preserving the symmetry and purity of the Dial. Fitted with a rugged black sail-canvas strap secured by a traditional pin buckle, the Bathyscaphe 5100B-1110-B52A balances professional-grade functionality with an effortlessly modern aesthetic. With a water resistance of 300 meters, it upholds the performance standards of the Fifty Fathoms line while offering a versatile and luxurious take on the modern dive watch.
