The Longines Master Collection Date 25.5 Stainless Steel - Diamond / MOP takes a 13 mm strap: measure between the lugs and that is the only number you need. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 25.5 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.
