The Longines Flagship 30 Stainless Steel / Green / Bracelet takes a 15 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 30 mm case and 30 m of water resistance, a strap of medium thickness keeps the balance. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
