The two Fifty Fathoms Bathyscaphe models feature sharp silhouettes and satin finishes exuding a sense of stealthy refinement. Set atop are their robust unidirectional rotating bezels with blue ceramic inserts and Liquidmetal® hour-markers. The Bathyscaphe’s crystal-clear legibility and razor-sharp detailing are juxtaposed by the warm and inviting blue tones of the dial, whose shimmering reflections play with light thanks to a beautifully executed sunburst finish. Rectangular hands and chapter rings composed of gold and Super-LumiNova® dots evoke Blancpain’s historical Bathyscaphe editions.   

Forged in steel, the 38mm Bathyscaphe is equipped with Blancpain’s renowned self-winding Calibre 1150. The 43mm version is crafted from grey ceramic and powered by Calibre 1315, a technical and precision timekeeping benchmark in the realm of luxury sports watches.  

Both movements are visible through a sapphire case-back revealing all the beauty of a sandblasted and satin-finished 18K gold winding rotor engraved with the Blancpain logo, along with snailed and beveled bridges.   

Exclusively for Oceana’s SeaChange 2022 auction winner, Blancpain offers the possibility to make the timepieces unique by replacing the Blancpain logo on the winding rotor with a personalized engraving. Engraving is not part of the standard offering within any Blancpain boutique, so this is a rare opportunity to personalize the watches that define the standards of fine-diving watches for the entire industry.  

Water-resistant to 30 bar, equivalent to 300 meters, both watches are offered on sail-canvas straps.

About Blancpain & the Fifty Fathoms 

Established in 1735, Oceana’s partner Blancpain is recognized as the world’s oldest watch brand. For nearly three centuries, its tradition has been innovation, and it is a major innovation that established the brand’s bonds with the ocean.   

In 1953, Blancpain presented the first modern diving watch, the Fifty Fathoms. Then CEO Jean-Jacques Fiechter, a passionate diver who realized the vital importance of reliably measuring time underwater, thus marked both diving and watchmaking history defining the standards of fine dive watches for the entire industry. A true tool watch, the Fifty Fathoms was immediately adopted by elite military units around the world, including the French Nageurs de Combat, the US Navy Seals and UDT, the German Kampfschwimmer, and many more.  

Three years later, in 1956, Blancpain brilliantly presented the Bathyscaphe model as a reliable diver’s watch whose size would make it suitable for everyday wear. Named after the deep-diving submersible invented by the Swiss physicist and explorer Auguste Piccard, the original Bathyscaphe dive watch was introduced as the civilian complement to the more professional Fifty Fathoms. It came in a smaller size and was targeted toward the recreational diving market.
