Strap for De Ville Trésor 36 Moonshine Gold / Malachite

The Omega Trésor 428.58.36.60.99.001 requires a strap with a lug width of 18 mm. This measurement represents the internal distance between the two holes of the lugs on the case. To verify it, remove the original strap and measure with a digital calliper: the correct tolerance is 17.8-18.2 mm. A lug width that is too narrow causes mounting difficulties; a lug width that is too wide generates excessive play during use.

Alligator represents the most coherent choice: the grain texture visually dialogues with the linear geometry of the dial, and the natural flexibility of the leather pairs perfectly with the 36 mm proportions. Shell cordovan offers exceptional longevity with a natural patina over time. Italian calf with vegetable tanning represents the optimal compromise between initial softness and aesthetic aging, developing a golden patina that reflects the evolution of the Moonshine Gold.

Position the watch on a soft surface. Locate the spring bars (the horizontal pins that support the strap). Use a spring bar tool—available from Casati Milano or in commerce—to gently push the pin from one side to the other. Once the pin is extracted, the strap comes free. To mount the new strap, align the holes and reinsert the pin. Verify that the movement is smooth and that the strap adheres symmetrically to the case.

Yes, provided the lug width is 18 mm. Aftermarket straps offer greater aesthetic variety and controlled longevity compared to the original. Always verify numerical compatibility before purchase. At milanostraps.it you will find a selection of 18mm straps in alligator, calf, and shell cordovan, customisable in sizes and stitching colour, with fast shipping.

Durability depends on the material and use. Alligator, with natural tanning, maintains structural integrity for 4-6 years under daily wear conditions. Shell cordovan, thanks to its dense fibrous structure, reaches 6-10 years. A vegetable-tanned calf lasts on average 3-5 years, developing a natural patina that signals aesthetic aging rather than degradation. The Casati Milano atelier applies an 18-month warranty on all bespoke straps and recommends annual preventive maintenance.
