Blancpain X Swatch Fifty Fathoms "Scuba Fifty" Atlantic Ocean Blue Dragon Edition in Bioceramic 42.3mm. The deep and intense blue shades of the ATLANTIC OCEAN model pay tribute to the stormy seas and raging waves of the Atlantic. Glaucus Atlanticus was the inspiration for the colors of its Bioceramic case, gradient dial with a date indicator between 4 and 5 o’clock. Fitted on a stunning blue leather strap with blue stitching.

Blancpain X Swatch honors the first true diver’s watch: the Fifty Fathoms. Created 70 years ago by a passionate scuba diver, it revolutionized watchmaking by becoming the first timepiece that successfully met all the needs of underwater exploration.

This magnificent animal, also known as the blue dragon, can be found drifting on the surface of the Atlantic and on the back of this timepiece equipped with a SISTEM51 movement which can be seen through the skeleton exhibition case back.

It’s water-resistant to 91m - Why 91 meters? That’s the equivalent of 50 fathoms, a British unit of measurement, and what the original Blancpain Fifty Fathoms of 1953 was rated to.

This Blancpain X Swatch watch honors Blancpain’s Fifty Fathoms, the first true diver’s watch. Its blue case and crown are made of Bioceramic material. The word “Swatch” is inscribed on the outer left side of the case. The metal dial is printed in several layers of color for a gradient effect. The hour indexes, hour, and minute hands, as well as the scale on the bezel, are enriched with Grade A Super-LumiNova for outstanding legibility in the dark. The one-direction rotating ocean blue-colored Bioceramic bezel, and biosourced glass are treated with an anti-scratch coating. The SISTEM51 mechanical movement is visible thanks to a transparent sapphire glass and features an illustration of the Atlantic Ocean and the Glaucus Atlanticus nudibranch in digital print. Five inspirational inscriptions can be found on the back of the watch: PASSION FOR DIVING – LICENCE TO EXPLORE – OCEAN BREATH – PROTECT WHAT YOU LOVE and IMMERSE YOURSELF.
