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

The lug width of the Omega Trésor 428.55.26.60.99.001 is 13mm. This dimension has been calculated proportionally to the 26mm case diameter to maintain aesthetic balance and ensure that the strap does not protrude beyond the case profile. It is essential to measure the lug width correctly – the distance between the two outer lugs – before purchasing a compatible custom strap.

Shell cordovan in vegetable tanning is the ideal choice for Moonshine Gold. Cordovan develops a deep patina over time that dialogues magnificently with the soft and warm luminosity of the gold. Black or brown alligator represents a formal and versatile alternative, while cognac-coloured calf offers tonal harmony. Avoid overly structured materials that would compete with the elegant and discreet character of the case.

Strap replacement requires a spring bar tool. Position the watch so that the lugs are accessible, insert the tool into the small hole or slot under the lug, apply gentle pressure to retract the spring bar, then remove the old strap. Insert the new strap by threading the spring bar into the lug and letting it snap into position. For the Trésor 428.55.26.60.99.001 with 13mm lug width, ensure that the strap has been constructed specifically for this measurement.

Yes, provided the strap is specifically designed for 13mm lug width. Many standard straps are not compatible with this unusual width. Milano Straps offers a collection dedicated to 13mm straps, constructed to watchmaking tolerances that guarantee precise fit on the 428.55.26.60.99.001. An undersized strap would leave the watch unstable; an oversized one could not accommodate the lug internally.

The durability of a custom strap depends on the material chosen and its use: shell cordovan in vegetable tanning, subjected to daily wear, can last 3-5 years or longer, developing a desirable patina. Alligator typically resists for 2-3 years before showing signs of aging. Calf, more delicate, has an average lifespan of 18-30 months. Casati Milano provides an 18-month warranty on all custom straps, covering construction defects and stitching.
