Strap for Master Collection Date 38.5

The Longines Master Collection L2.628.5.79.7 features a lug width of 20 mm. This measurement represents the internal distance between the two lugs of the case and determines strap compatibility. To verify this measurement precisely, place a ruler between the inner shoulders of the lugs, without considering the external case width. The 20 mm dimension is the ideal standard for this 38.50 mm diameter model.

For the Master Collection L2.628.5.79.7, we recommend Nile alligator in cognac or dark brown, which amplifies the classical aura without adding artificiality. An elegant alternative is vegetable-tanned calf with natural texture and matte patina. Shell Cordovan represents the choice for extraordinary longevity. For sports use, dark-toned rubber is practical and appropriate. Avoid straps with irregular texture or saturated colours: the Longines is architecture, not canvas.

Changing the strap requires a specific tool: a spring bar removal tool. Position the watch on a soft surface. Insert the tool into the slot beneath the lug and gently push the pin upward to release it, then extract the strap end from the lugs. Repeat on the other side. To install the new strap, align the holes with the pins and use the tool to compress the pin, inserting the strap securely. Verify that the strap is fixed symmetrically on both sides.

Yes, the L2.628.5.79.7 is fully compatible with quality aftermarket straps, provided they have a 20 mm lug width. Milanostraps offers straps in alligator, calf, shell cordovan and other materials, all available in the 20 mm size and customisable in length, stitching and finishing. Ensure the strap is proportioned to the 38.50 mm case diameter to maintain aesthetic balance.

Durability depends on material and usage. Quality Nile alligator lasts 5-7 years with regular rotation and basic maintenance. Vegetable-tanned calf resists 3-5 years. Shell Cordovan, if cared for, easily exceeds 7-10 years. Factors influencing longevity: ambient humidity, sun exposure, frequency of use and water contact. Regular maintenance—cleaning with soft cloths, nourishing cream every 6-8 months—significantly extends strap life.
