When it comes to amphibious timepieces, Blancpain is unparalleled in its expertise. After all, it's not only one of the oldest Switch watchmakers, but is universally regarded as having presented the first fit-for-purpose modern diver's watch in 1953 - the Fifty Fathoms. This would become the blueprint for future diving watches such as this Fifty Fathoms Bathyscape iteration, boasting a 50-hour power reserve, 30 bar water resistance (300m) and Liquidmetal hour markers. ,
