Blancpain X Swatch Fifty Fathoms Scuba Collection: Ocean of Storms SO35B400

The Ocean of Storms: New Moon is the boldest expression in the Blancpain X Swatch Fifty Fathoms Scuba collection — a celebration of deep-sea heritage, modern sustainability, and mechanical innovation. A tribute to the legendary Fifty Fathoms, this timepiece merges the soul of a classic diver’s watch with futuristic materials and purpose-driven design.

Encased in black Bioceramic, the 42.3 mm case is sculptural and sleek, accented by the engraved “Swatch” insignia and paired with a one-direction rotating bezel in matching Bioceramic. A sunbrushed black dial anchors the design, discreetly housing a date window between 4 and 5 o’clock. Grade A Super-LumiNova® applied to the indexes, hands, and bezel ensures superior legibility in low light.

Underneath, the SISTEM51 mechanical movement is visible through a transparent caseback, showcasing not only its single central screw but a vibrant digital print of Oceanus Procellarum and the Okenia Luna nudibranch — a nod to the lunar inspiration behind this release.

The watch is fitted with a NATO strap made from recycled fishing nets, secured by a black Bioceramic buckle and loops, echoing the collection’s deep connection to ocean preservation. Engraved with the phrase "PROTECT WHAT YOU LOVE", the caseback serves as a quiet reminder of the importance of protecting marine environments.
