The Longines La Grande Classique Automatic 36 Stainless Steel / Yellow Gold PVD / White takes a 18 mm strap: measure between the lugs and that is the only number you need. We list 31 straps in that width. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 36 mm case and 30 m of water resistance, a strap of medium thickness keeps the balance. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
