The Ralf Tech WRV Electric Black "Pirates Shadow" takes a 26 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 43.8 mm case and 300 m of water resistance, a thicker strap balances the case. Electronic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
