Frequently asked questions

What is the exact lug width of the Omega Trésor 428.17.26.60.04.006?

The lug width of the Omega Trésor 428.17.26.60.04.006 is 13mm. This measurement refers to the distance between the pins that secure the strap to the case lugs. It is essential to measure it correctly on both sides to ensure mechanical compatibility with aftermarket straps.

What type of strap is recommended for the Omega Trésor 428.17.26.60.04.006?

For the Trésor we recommend natural alligator, which creates an elegant contrast with the polished stainless steel case, or shell cordovan for superior construction density. For everyday contexts, smooth calf or canvas offer good harmony with the compact proportions of the 26mm case.

How do you change the strap on the Omega Trésor 428.17.26.60.04.006?

The strap is removed by extracting the metal pins from the case lugs using dedicated spring bar removal tools. This work must be performed carefully to avoid scratching the polished stainless steel case. It is recommended to have the operation carried out by qualified watchmakers, especially for valuable timepieces.

Are there aftermarket straps compatible with the 428.17.26.60.04.006?

Yes, milanostraps.it offers a wide selection of 13mm straps compatible with the Trésor, available in various materials (alligator, calf, vegetable tanning, rubber). All straps are customizable in size, initials, and choice of stitching thread.

How long does a leather strap last on the Omega Trésor?

The lifespan of a leather strap depends on the material and usage. With vegetable tanning, approximately 3-4 years with moderate wear. Shell cordovan offers greater longevity (5-6 years), while natural alligator maintains excellent condition for 4-5 years if properly cared for. The warranty offered by Casati Milano is 18 months.
