Strap for Mini Trésor Quartz 26 Moonshine Gold - Diamond / White Enamel / Double Tour

The lug width of model 428.57.26.60.04.005 is 13mm. This measurement identifies the distance between the two spring bar attachments of the case and is crucial for compatibility with any aftermarket strap or bracelet. Always verify manually with a digital caliper before making a purchase.

For the Trésor 428.57.26.60.04.005, cognac or medium brown alligator represents the most coherent choice: the well-defined grain texture naturally complements the warm tone of Moonshine Gold and the microtexture of the bezel. Alternatively, vegetable-tanned calf leather in bordeaux or natural brown tones, which develops patina over time, or grey technical rubber for those who prioritize everyday functionality.

Use a spring bar tool, a dedicated instrument with two concave ends. Position one end inside the hole of the lower lug, push downward to release the spring bar attachment, then slide the old strap in a transverse direction to release it completely. Repeat the operation on the other side. Insert the new strap into the lugs following the reverse procedure, ensuring that both spring bar attachments are correctly positioned.

Theoretically yes, but with attention to aesthetic context. A 13mm strap is mechanically compatible; however, on a 26mm case the visual proportions become critical. Avoid straps that are too thick or rigid and do not adapt to the proportional harmony of the case. Milano Straps provides straps verified for compatibility, eliminating the risk of mounting errors.

The lifespan depends on the material, tanning method, and usage. Alligator or vegetable-tanned calf leather, worn daily with moderation (avoiding excessive moisture, concentrated sweat, and extreme bending), maintains functional integrity for 3-5 years. The patina that develops tells the story of use. Casati Milano provides an 18-month warranty on custom straps and offers maintenance services and stitching replacement.
