Longines · La Grande Classique
Ref. L45124512
The Longines La Grande Classique Quartz 29 Stainless Steel / Black - Roman takes a 16 mm strap: measure between the lugs and that is the only number you need. We list 9 straps in that width. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 29 mm case and 30 m of water resistance, a strap of medium thickness keeps the balance. Quartz movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
Width is a starting point. Check the case and end fittings before choosing.
