Strap for Master Collection Date 38.5 Two Tone Arabic

The lug width of the Longines Master Collection L2.628.5.78.7 is 20 mm. This dimension is standard for the model and calculated to maintain correct proportions between the 38.50 mm case and optimal wrist fit. Measure perpendicular to the inner lug, not the outer edge, to avoid purchasing errors.

For the Master Collection L2.628.5.78.7, we recommend natural alligator in dark brown or black, which enhances the yellow gold bicolour case and maintains the formal tone of the model. As an elegant alternative, vegetable-tanned calf offers a fascinating patina development. For daily wear, dark rubber or neutral NATO ensure versatility.

To change the strap, remove the watch from your wrist. Locate the small spring bars on each side of the lugs. Use a dedicated spring bar tool to compress the spring and extract it from the lug holes. Insert the new strap by engaging the springs into the opposite seatings. Never force manually—the movement should be fluid.

Yes, any quality strap with 20 mm lugs is compatible with the L2.628.5.78.7. Artisanal milanostraps.it straps are specifically tested for Master Collection proportions. Verify that the spring bars seat correctly in the bevelled lugs of the case.

A quality leather strap, with vegetable tanning or natural alligator, lasts an average of 3–5 years with daily wear, depending on humidity and heat exposure. Alligator is more durable than calf. Casati Milano's warranty covers 18 months. To extend life, avoid frequent immersion and apply leather conditioner every 6 months.
