Strap for De Ville Trésor 36 Moonshine Gold / Moonshine Silk / Mesh

The lug width of the Trésor 428.55.36.60.99.001 is 18 millimetres. This measurement represents the distance between the two metal supports of the case where the strap is inserted. An 18mm strap must fit without forcing and without excessive play. To verify the correct measurement, use a digital caliper on the internal distance between the lugs.

Hand-dyed natural alligator represents the most coherent choice: the regular scale texture dialogues with the Moonshine finish of the case without competing visually. Shell cordovan is ideal for those desiring water resistance and patina that improves over time. Vegetable-tanned calf leather with traditional tanning offers a more informal approach while maintaining elegance. Avoid combinations with glossy or artificial finishes that would clash with the sobriety of the design.

To change the strap, you need a specific tool (spring bar tool) to compress the internal springs that secure the strap to the lugs. Position the tool on the small hole of the spring, gently compress and extract the strap. Repeat on the other side. Insert the new strap by aligning the springs in the lug holes. The procedure requires precision: if you are not experienced, entrust a professional watchmaker to avoid damage to the case supports.

Yes, any strap with an 18mm lug width is compatible with the Trésor. However, construction quality varies significantly. Artisanal straps from milanostraps.it guarantee measurement conformity, precise finishes and selected materials. Ensure that the strap you purchase is specifically sized for 18mm and not for approximate sizes such as 17.5mm or 18.5mm.

The longevity of a leather strap depends on use, tanning and maintenance. An alligator strap with well-cared-for vegetable tanning lasts 3-5 years of daily use. Shell cordovan, thanks to its natural density, exceeds 5 years even in humid environments. Perspiration, moisture and sun exposure accelerate wear. Occasional protective treatment (natural wax) and rotational rest with other straps significantly extends durability. Casati Milano offers an 18-month warranty on its artisanal straps.
