Strap for De Ville Trésor Master Chronometer Small Seconds Stainless Steel / Grey

The lug width of the Omega Trésor 435.13.40.21.06.001 is 20 millimeters. This parameter is critical when purchasing compatible aftermarket straps. Omega has specifically calibrated this width to maintain the correct visual proportions between the case diameter (40mm) and the strap thickness.

Alligator leather represents the most coherent choice with the model's formal-elegant identity: the American grain texture creates chromatic depth and a patina that ages with nobility. Shell cordovan offers tactile density and a specular patina after months of wear. For a sporty-elegant approach, vegetable-tanned calf leather ensures chromatic versatility and wearability on the wrist.

Use a digital caliper to measure the distance between the two strap attachment pins (lugs). The measurement must be perpendicular to the case and should be taken with the strap removed. The value obtained represents the correct lug width: in the case of the Trésor 435.13.40.21.06.001, it is exactly 20 millimeters.

Yes, the Trésor 435.13.40.21.06.001 is compatible with any strap featuring a 20-millimeter lug width. Before purchase, verify that the strap has a total length compatible with your wrist and that the attachment pins are correctly dimensioned. All 20mm straps available online at milanostraps.it are compatible with this reference.

The lifespan of a leather strap depends on the intensity of wear, climatic conditions, and the quality of the tanning. A high-quality artisanal alligator or shell cordovan strap can withstand 5-7 years of daily wear without significant degradation. Materials such as vegetable-tanned calf tend to patina more quickly but maintain structural functionality for similar periods. The Casati Milano atelier offers an 18-month warranty on all custom-made straps.
