This Blancpain X Swatch timepiece pays homage to Blancpain's Fifty Fathoms, the first true diver's watch. The black case and crown are made of Bioceramic material, with the word "Swatch" engraved on the left side of the case. The dial is sunray black and features a date indicator between the 4 and 5 o'clock positions. The hour markers, hour and minute hands, and bezel markings use Grade A Super-LumiNova® for excellent visibility in the dark. The black Bioceramic unidirectional rotating bezel and bio-sourced glass have scratch-resistant coatings. The SISTEM51 mechanical movement is visible thanks to the transparent sapphire glass, which features a digital print of the "Ocean of Storms," a vast plain on the moon's surface, and an illustration of the sea slug Okenia Luna. The NATO strap is made from recycled fishing nets, and the pin buckle and loops are made of Bioceramic material. The retail price is ¥60,500. ● Manufacturer: SWATCH ● Product Name: Blancpain x Swatch OCEAN OF STORMS ● Drive System: Automatic winding ● Model No.: SO35B400 ● Dial Color: Black ● Case Material: Bioceramic ● Case Size: Case Diameter: 42.3 mm, Case Thickness: 14.4 mm ● Accessories: Cosmetic box, card (with description), instruction manual The previous owner: Purchased from a Swatch authorized dealer at Nagoya Mitsukoshi in May 2024 and replaced the strap with an aftermarket rubber strap. ※ The original strap is like new. ※ The rubber strap shows signs of use.
