The Longines Flagship 25 Quartz Stainless Steel Black 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 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.
