Festina · Swiss Made
Ref. F20016/2
The Festina Swiss Made Homme takes a 20 mm strap: measure between the lugs and that is the only number you need. We list 37 straps in that width. With a 39.3 mm case and 50 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.
