The Omega Seamaster Planet Ocean 600M Co-Axial 45.5 Master Chronometer GMT Deep Black Sedna takes a 22 mm strap: measure between the lugs and that is the only number you need. We list 36 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 45.5 mm case and 600 m of water resistance, a thicker strap balances the case. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
Width is a starting point. Check the case and end fittings before choosing.
