The Tissot Seastar 1000 Quartz 40 Wilson WNBA / White takes a 20 mm strap: measure between the lugs and that is the only number you need. We list 37 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 40 mm case and 300 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.
