The Breitling B55 Exospace Titanium / Black / TwinPro Grey / Folding takes a 24 mm strap: measure between the lugs and that is the only number you need. We list 18 straps in that width. With a 46 mm case and 100 m of water resistance, a thicker strap balances the case. 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.
