Ref. AL371BG4S6
The Alpina Startimer Pilot Chronograph Quartz 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 field or pilot watch at heart, it suits canvas, nylon and matte leather more than polished calf. With a 42 mm case and 100 m of water resistance, a thicker strap balances the case. 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.
