Strap for De Ville Trésor 36 Moonshine Gold / Malachite / Bracelet

The Omega Trésor 428.55.36.60.99.003 features a lug width of 18mm. This classic standard is determined by the 36mm case and ensures harmonious proportions between the watch body and the strap. You can verify the lug width by positioning a digital caliper on the inner shoulders of the lugs or by consulting official Omega documentation.

For the Trésor in Moonshine Gold, dark brown or burgundy alligator represents the optimal choice: its regular grain texture naturally complements the polish of the case without competing. Vegetable-tanned calf offers a more tactile alternative with a patina that evolves over time. For formal settings, shell cordovan ensures durability and sophistication. FKM rubber with steel deployant clasp remains ideal for travel contexts and versatile everyday use.

Changing the strap on an 18mm lug width watch is accomplished using a spring bar tool (fork-shaped instrument). Position the tool under the lug, push gently to compress the internal spring of the bar and make it snap out of its seat. Repeat for the other side. To insert the new strap, align the holes at the ends of the lugs and press gently until it clicks. If you are not experienced, consult a specialist to avoid scratching the case.

The durability of a leather strap varies based on material, frequency of use, and environmental conditions. A quality alligator strap, with vegetable tanning and artisanal finishing, can last 3–5 years with daily use, especially if subjected to regular care (avoid prolonged water exposure, direct sunlight, and extreme humidity). Shell cordovan tends to last longer thanks to the natural fiber density. A standard calf strap lasts 2–3 years. The Casati Milano atelier offers an 18-month warranty on its work.
