Blancpain X Swatch pays homage to the first true diving watch: the Fifty Fathoms. Created 70 years ago by a diving enthusiast, it revolutionized watchmaking by becoming the first watch capable of meeting all the needs of underwater exploration. The mechanical watches of the Bioceramic Scuba Fifty Fathoms collection faithfully reproduce all the distinctive features of this Swiss watchmaking icon and reference SCUBA, our line of diving watches. Each model in the collection celebrates an ocean and one of the magnificent and colorful animals known as nudibranchs, represented in digital print on the movement's rotor.
