This is the "Ocean of Storms" model (Reference: SO35B400) from the revolutionary Blancpain X Swatch Bioceramic Scuba Fifty Fathoms collection. Unlike the other models inspired by Earth's oceans, this watch is dedicated to the Moon's largest mare, the Oceanus Procellarum (Ocean of Storms), and is distinguished by its stealthy all-black colorway, inspired by the New Moon. It perfectly blends Blancpain's dive watch heritage with Swatch's modern, accessible approach. Key Features: In-House Automatic Movement: Powered by the SISTEM51 mechanical movement. This Swiss-made automatic caliber is composed of only 51 parts, features a fully anti-magnetic Nivachron balance spring, and boasts an outstanding 90-hour power reserve. Bioceramic Case: The 42.3mm case is made from Swatch's innovative Bioceramic material, a blend of ceramic and bio-sourced plastic, offering a light yet durable feel. Dive Specifications: Features a black unidirectional rotating bezel and a water resistance of 50 fathoms (91 meters / 300 feet), in keeping with the historical name. Unique Design Details: The transparent caseback features a digital print of the Oceanus Procellarum lunar mare and the Okenia Luna nudibranch (sea slug) on the rotor, adding a celestial and marine touch. Strap: Comes on a black and white NATO strap crafted from recycled fishing nets. This is the ultimate collaboration timepiece for collectors and enthusiasts looking for a piece of watchmaking history with a modern, all-black aesthetic. - Appearance - Scuffs from normal use. *Please check photos.
