The Longines Master Collection 42 Chronograph Calendar Stainless Steel / Anthracite takes a 21 mm strap: measure between the lugs and that is the only number you need. We list 216 straps in that width. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 42 mm case and 30 m of water resistance, a thicker strap balances the case. Automatic movement. 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.
