Trésor 428.57.26.60.04.002— lug 13mm

The lug width of the Trésor 428.57.26.60.04.002 is exactly 13mm. This non-standard dimension is specific to the model and must be respected when choosing a strap to ensure correct assembly and balanced optical proportions.

The Trésor in Moonshine Gold pairs ideally with alligator straps (natural texture that contrasts with the golden case), calf leather with patina that evolves over time, or shell cordovan for timeless elegance. The choice depends on the intended use and the desired chromatic dialogue. Available online and customizable through Casati Milano.

The Trésor uses standard spring bar lugs. To remove the strap, use a small tool (spring bar tool) to compress the spring and extract the pin from the case lugs. Proceed with caution given the compact size of the piece. If unsure, entrust the operation to a specialized craftsman.

Yes, provided the lug width is exactly 13mm. Milano Straps artisanal straps are designed and crafted in Italy to be compatible with the Trésor. Always verify the <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-13mm">lug width</a> before purchase.

A quality leather strap (alligator, calf, shell cordovan) lasts on average 3-5 years with daily use, depending on frequency of use, climate, and maintenance. Vegetable tanning and shell cordovan develop patina over time, improving aesthetically. Artisanal straps from Casati Milano include an 18-month warranty.
