Strap for De Ville Trésor Master Chronometer Power Reserve Yellow Gold / Silver

The Omega Trésor reference 435.53.40.22.02.001 is equipped with a lug width of 20 mm. This measurement represents the distance between the inner edges of the two case lugs and determines compatibility with aftermarket straps. To verify the lug width of your Trésor, remove the original strap and measure with a caliper the distance between the two lateral case attachments.

For a Trésor in 18k yellow gold, we primarily recommend natural alligator in dark brown or black tones: the regular texture and the patina that develops over time create superior visual harmony with the precious metal case. Alternatively, shell cordovan offers exceptional construction density and a fascinating accelerated patina, while vegetable-tanned calfskin represents a more accessible solution that develops a unique and personal patina.

The Trésor uses a standard removable lug system. To change the strap: 1) Remove the original strap by gently prying the spring bars from the ends with a dedicated tool (spring bar tool); 2) Insert the new 20mm spring bars of the strap into the lateral case attachments; 3) Push until you hear the locking click. If you are not experienced, we recommend having a professional assist you to avoid damage to the case.

Yes, all straps with 20mm lug width are compatible with the Trésor 435.53.40.22.02.001. Milano Straps offers a curated selection of 20mm straps in precious materials (alligator, calfskin, shell cordovan) customizable in sizes, initials, and stitching thread, ensuring construction quality and aesthetics worthy of the watch.

The lifespan of a leather strap depends on the material and usage. Alligator and shell cordovan, noble and dense materials, offer an average lifespan of 3-5 years with daily use and ordinary maintenance (gentle cleaning and drying). Vegetable-tanned calfskin has a similar lifespan but develops a faster patina. Factors such as perspiration, humidity, and frequency of use directly affect longevity. Milano Straps guarantees 18 months on custom Casati straps.
