Discover the Swatch x Blancpain Bioceramic Scuba Fifty Fathoms Atlantic Ocean SO35A100, an automatic dive-inspired watch created through the collaboration between Swatch and Blancpain.

The Atlantic Ocean edition brings a deep blue aesthetic to the Bioceramic Scuba Fifty Fathoms collection. Its case and crown are made from blue Bioceramic, while the gradient dial uses multiple layers of color to create a rich ocean-inspired appearance. The outer left side of the case is inscribed with the word “Swatch.”

The watch measures 42.3mm in diameter, with a 14.4mm case thickness and 48mm lug-to-lug distance. Its blue Bioceramic construction gives the watch a distinctive modern appearance while maintaining the recognizable diving-watch design language of the Fifty Fathoms-inspired collection.

Powering the Swatch Blancpain Atlantic Ocean SO35A100 is the Swiss-made SISTEM51 mechanical movement. The automatic movement contains 51 parts and one central screw, offers approximately 90 hours of autonomy, and uses a Nivachron™ hairspring for anti-magnetic performance.

The gradient dial is paired with a dark blue unidirectional Bioceramic bezel featuring a black insert. The hour indexes, hour and minute hands, and 60-minute diving scale are enhanced with Grade A Super-LumiNova® for improved visibility in low-light environments.

Through the transparent sapphire display back, the SISTEM51 movement can be viewed along with an illustration of the Atlantic Ocean and Glaucus Atlanticus nudibranch. The caseback also features five inspirational inscriptions: “PASSION FOR DIVING,” “LICENCE TO EXPLORE,” “OCEAN BREATH,” “PROTECT WHAT YOU LOVE” and “IMMERSE YOURSELF.”

The watch is finished with a NATO strap made from recycled fishing nets removed from the sea, while the pin buckle and loops are made from Bioceramic material. Water resistance is rated at 50 fathoms / 91m / 300ft / 9 bar.
