The Certina DS-8 Chronograph Moon Phase Stainless Steel / Gold / Bracelet takes a 21 mm strap: measure between the lugs and that is the only number you need. We list 6 straps in that width. A chronograph carries a bit of sport: perforated leather, rubber or a sailcloth strap all sit well. With a 41 mm case and 100 m of water resistance, a strap of medium thickness keeps the balance. Quartz 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.
