FAQ

What is the lug width of the Omega Trésor 428.17.26.60.04.002?

The lug width of the 428.17.26.60.04.002 model is exactly 13 millimetres. This width represents a specific standard for this model and requires straps compatible with this precise dimension to ensure correct positioning between the case lugs.

Which strap material is most suitable for the Omega Trésor 428.17.26.60.04.002?

For the Trésor 428.17.26.60.04.002 we recommend vegetable-tanned alligator for classic elegance, nappa calf with natural patina development for contemporary style, or high-end FKM rubber for everyday practicality. The choice depends on your personal style and the intended use of the watch.

How do you change the strap on the Omega Trésor 428.17.26.60.04.002?

Strap replacement requires specific tools: a spring bar tool to extract the elastic pins that hold the strap to the lugs. Remove the old strap, insert the new one by aligning the lugs, and secure the elastic pins. If you are not experienced, we recommend consulting a professional watchmaker.

Are there quality aftermarket straps compatible with the 428.17.26.60.04.002?

Yes. On milanostraps.it you will find a complete selection of 13mm straps in leather, rubber and textile, made with careful material selection and available with customization of measurements, initials and stitching thread. The Casati Milano atelier also offers bespoke straps made to measure with direct leather selection.

What is the average lifespan of a leather strap for the Omega Trésor?

A quality leather strap (alligator or calf) has an average lifespan of 3-5 years with regular use, considering exposure to sweat, humidity and UV rays. Vegetable tanning tends to patina naturally, improving aesthetically over time. The standard warranty offered by Milano Straps is 18 months for bespoke straps.
