Strap for Mini Trésor Quartz 26 Moonshine Gold - Diamond / Moonshine Gold

The Omega Trésor 428.58.26.60.99.001 has a lug width of 13mm. This width is specific to the women's model and requires careful selection of aftermarket straps. Standard 16mm or 18mm straps cannot be used without compromising the aesthetics and functionality of the attachment. Correct measurement is performed with a digital caliper between the two lugs at the widest point of the attachment space.

For the Trésor in Moonshine Gold we recommend three main options: black alligator for formal and evening elegance, dark brown calf for daily versatility with warm color depth, or shell cordovan wine for those who appreciate natural patina and development over time. All straps must be 13mm wide to ensure compatibility with the case lugs. The choice depends on the primary context of use and the personal style of the wearer.

Changing the Trésor strap requires specific tools: a spring bar tool and a clean, protected work surface. Insert the flat tip of the tool under the spiral spring that supports the left lug, gently push to compress the spring, then extract the pin. Repeat for the right lug. The operation requires care: the Moonshine Gold case is not as scratch-resistant as steel. If you lack experience, entrust the work to an Omega professional or a specialist craftsman such as Casati Milano.

Yes, the Trésor accepts 13mm aftermarket straps, but commercial availability is limited compared to standard widths (16mm, 18mm, 20mm). Our 13mm artisanal straps are custom-made using excellent quality leathers such as alligator, shell cordovan, Italian calf, and vegetable-tanned leather. All our straps are fully compatible with the Trésor's spiral spring attachment system and available with Omega deployant or custom buckle.

The lifespan of a leather strap depends on the type of leather and intensity of use. A good quality alligator strap typically lasts 5-7 years with moderate daily use, thanks to the natural durability of the leather. Shell cordovan can last 10+ years as it is one of the most resistant leathers in the world. High-end Italian calf straps last 4-6 years. Vegetable-tanned leather develops a patina over time and can be reconditioned to extend its life. All Casati Milano straps include an 18-month warranty against manufacturing defects and materials.
