The G-Shock Utility Metal takes a 21 mm strap: measure between the lugs and that is the only number you need. We list 6 straps in that width. Built for water, it wears naturally on rubber or a nylon NATO; a leather strap keeps it for dry days. With a 44.4 mm case and 200 m of water resistance, a thicker strap balances the case. Quartz movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
