Strap for Master Collection 38.5 Day Date Stainless Steel / Silver-Arabic / Alligator XL

The lug width of the Longines Master Collection L2.755.4.78.5 is 20mm. This dimension represents the distance between the two lugs of the case and determines strap compatibility. You can verify it by measuring the gap between the lugs using a calliper.

The best strap depends on intended use. For formal elegance, we recommend polished alligator or calf leather with vegetable tanning. For versatile sportiness, shell cordovan offers durability and natural patination. Ideal colours include cognac brown, formal black, or deep burgundy for personality whilst maintaining sobriety.

To change the strap, use a spring bar removal tool. Position the tool gently beneath the elastic spring bar holding the strap, apply upward pressure to release it, then remove the strap from the first lug. Repeat on the opposite lug. Insert the new strap in reverse sequence, ensuring the spring bar is fully seated in both lugs.

Yes, you can use quality aftermarket straps with 20mm lug width. Ensure the strap is specifically designed for this width and that the lug thickness is compatible with the original. Milano Straps offers custom-crafted straps with warranty, customisable in leather, colour and stitching details.

The lifespan of a leather strap depends on tanning type and use intensity. A strap made with vegetable tanning or shell cordovan can last 3-5 years with regular wear. Polished alligator tends to resist longer. Regular maintenance—protection from excess moisture and gentle cleaning—significantly extends longevity. Casati Milano guarantees its straps for 18 months.
