Strap for De Ville Trésor Master Chronometer Small Seconds Stainless Steel / Diamond / Silver

The lug width of the Omega Trésor 435.18.40.21.02.002 is 20 millimetres. This measurement represents the distance between the two anchor pins of the strap and is decisive when selecting compatible straps. A strap with a lug width smaller or larger than 20mm will not fit correctly on this model.

For the Omega Trésor 435.18.40.21.02.002 we recommend materials that respect the sober elegance of the model: alligator in dark brown or cognac tones, black calf with satin finish, shell cordovan for those desiring a leather that develops patina over time, or natural black rubber for more dynamic uses. The choice depends on your context of use and personal colour preferences.

Changing the strap on the Omega Trésor requires a spring bar removal tool or a small screwdriver. Position the watch with the case facing upwards, locate the small access hole next to each pin, insert the tool and push gently to release the pin. The new strap is inserted by aligning the two pins in their respective housings until they click into place. Never force: if a pin does not enter, it means the strap has a lug width not conforming to 20mm.

Yes, all straps with a 20mm lug width are compatible with the Omega Trésor 435.18.40.21.02.002. You can choose from a wide range of materials (alligator, calf, cordovan, rubber, NATO) available both ready to ship and customisable to measure through specialised artisans. Compatibility is guaranteed if the strap has exactly 20mm lug width.

The lifespan of a leather strap depends on the material and usage. A quality calf, with moderate use (3-4 days per week), lasts an average of 18-24 months before requiring replacement. Shell cordovan, thanks to the superior fibre density, can last 24-36 months. An alligator strap has a lifespan similar to calf. To extend durability, it is advisable to rotate multiple straps and allow the leather to rest between uses. Annual maintenance with a nourishing cream specific to leather significantly increases longevity.
