The Blancpain Fifty Fathoms Bathyscaphe Ocean Commitment II Flyback Chronograph takes a 23 mm strap: measure between the lugs and that is the only number you need. Built for water, it wears naturally on rubber or a nylon NATO; a leather strap keeps it for dry days. With a 43.6 mm case and 300 m of water resistance, a thicker strap balances the case. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
