The Longines Military 1938 Chronograph takes a 19 mm strap: measure between the lugs and that is the only number you need. We list 268 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 30 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.
We do not sell watches. This page exists to find the straps that fit this one.
