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

The lug width of the Omega Trésor 432.53.40.21.54.001 is 20mm. This is the internal distance between the two lugs of the case, measured at the narrowest point. It is essential to verify this measurement before purchasing a compatible strap, using a digital caliper for maximum precision.

For the Trésor in Sedna Gold we recommend a strap in mahogany alligator or burgundy shell cordovan. These materials create a harmonious dialogue with the warmth of rose gold, without competing visually. Vegetable-tanned calf in chocolate brown tones is also an excellent classic alternative that develops authentic patina.

The strap is changed through the spring bars present on both lugs. Using a dedicated tool (strap spoon or extractor tool), gently push the bar downward to release one end of the strap, then repeat from the other side. Maximum care must be taken not to scratch the Sedna Gold case. For a first operation, we recommend consulting a professional.

Absolutely yes. The Omega Trésor 432.53.40.21.54.001 is perfectly compatible with artisanal aftermarket straps in 20mm size. However, it is essential to choose a strap of high constructive quality (alligator, shell cordovan, calf), so that the aesthetics and durability are worthy of the prestige of the watch. Available straps online are customizable in exact measurements and thread stitching.

The lifespan of a leather strap depends on the material and usage. An artisanal quality alligator or shell cordovan strap lasts on average 3-5 years in daily use, with the possibility of extension through buckle replacement or targeted repairs. Vegetable-tanned calf, while softer, can last 2-3 years while maintaining structural integrity. Frequent exposure to moisture, sweat and sunlight accelerates wear. Custom straps from Casati Milano enjoy an 18-month warranty against manufacturing defects.
