Strap for De Ville Trésor Master Co-Axial Sedna Gold / Diamond / MOP

The lug width is exactly 20mm. This dimension represents the technical standard of reference 432.58.40.21.05.003 and is fundamental to ensure perfect fit to the case lugs, with no visible gaps and optimal wearing security during daily dressing.

High-quality alligator with satinized grain is the most coherent choice: it absorbs light in the same way as the Sedna Gold case, creating a harmonious aesthetic dialogue. Alternatively, cognac or chocolate brown calf offers better breathability and homogeneous texture ideal for daily use, while vegetable-tanned leather allows for a patina that develops parallel to that of the golden-rose case.

Use a digital caliper to measure the internal distance between the walls of the case lugs, that is from wall to wall. For the Trésor it is essential that the measurement is precisely 20mm. A strap that is too tight will create annoying gaps; one that is too wide will not penetrate correctly into the lugs and risks slipping during wear, compromising both aesthetics and security.

Yes, provided the lug width is strictly 20mm and the strap is constructed with quality materials (alligator, fine calf, vegetable-tanned leather). We recommend avoiding rubber or synthetic fabric, which contradict the manufacturing value of the object. A high-quality aftermarket preserves the character and prestige of the Trésor in Sedna Gold.

The lifespan depends on the intensity of use and the quality of the leather: an alligator or selected calf with vegetable tanning lasts an average of 3-5 years with daily wear in temperate climates. Prolonged exposure to sun, humidity and sweat accelerates wear. Straps stored with care and subjected to periodic maintenance (cleaning and light conditioning) can extend life to 7-8 years. The Casati Milano atelier guarantees 18 months on each creation.
