The Certina DS Action 34.5 Powermatic Stainless Steel - Yelllow Gold / Brown takes a 15 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 34.5 mm case and 200 m of water resistance, a strap of medium thickness keeps the balance. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
