Strap for Mini Trésor Quartz 26 Stainless Steel - Diamond / White Enamel / Double Tour

The lug width of the Trésor 428.17.26.60.04.005 is 13 millimetres. This rare measurement is specific to Omega's female models of this generation and represents the distance between the two spring bars that connect the case to the strap. It is essential to verify this measurement before purchasing an aftermarket strap to avoid incompatibility.

For the Trésor 428.17.26.60.04.005, straps in alligator, vegetable-tanned calf, or shell cordovan are recommended. Alligator maintains the compact proportion of the 26mm case without adding weight, thanks to its characteristic parallel texture. Calf leather offers a patina that develops rapidly, while shell cordovan represents a sophisticated choice for those seeking superior material density.

Changing the strap requires two tools: a spring bar removal tool or a small screwdriver. Position the watch with the strap side facing downward, locate the small opening next to the pin, insert the tool and push gently inward to compress the spring. Once the pin is extracted, remove the old strap and insert the new one following the reverse procedure. The operation requires care to avoid scratching the case.

Yes, Milano Straps offers a collection of aftermarket straps specifically compatible with the 13mm lug width that characterises the Trésor 428.17.26.60.04.005. All straps available online are tested to guarantee perfect fit. They can be personalised in sizes, initials and choice of stitching thread, or you can rely on the Casati Milano atelier for a bespoke creation with personal selection of leathers.

The lifespan of a leather strap depends on intensity of use, climate and material chosen. A quality alligator or calf leather strap, with moderate use and regular care, maintains structural integrity for 3-5 years. Progressive wear manifests with flattening of stitched edges and possible leather discolouration. Straps crafted by Casati Milano benefit from an 18-month warranty and can be regenerated over time through sole restoration or stitching interventions.
