Frequently asked questions

What is the exact lug width of the Omega Trésor 428.17.26.60.04.008?

The lug width is 13mm. This is the distance between the two case attachment pins, measured at the point where the strap connects. It is essential not to confuse this width with the total length of the strap. To verify this measurement, position a digital caliper between the two lugs: the value must be exactly 13mm to ensure compatibility.

What strap material is recommended for the Trésor 428.17.26.60.04.008?

For this elegant 26mm model, vegetable-tanned alligator is the noblest choice, particularly in black or dark brown for a formal effect. Alternatively, Italian calf or Japanese shell cordovan maintain sophistication. A silk-cotton NATO offers a more sporty approach while maintaining coherence with the minimalist design of the case.

How do you change the strap on an Omega Trésor?

The strap is changed by removing the attachment pins with the aid of a specialized spring bar remover tool. Position the tool in the groove next to the pin, apply light pressure to release the internal spring, and slide the pin upward. This operation requires delicacy to avoid scratching the case: many prefer to rely on a professional rather than risk damage.

Are aftermarket straps compatible with the Omega Trésor 428.17.26.60.04.008?

Yes, all artisanal straps with a 13mm lug width are compatible. On Milano Straps you will find a curated selection of straps ready for shipment, customizable in sizes, colors, and stitching thread. The Casati Milano atelier also offers a bespoke service with direct choice of leathers and an 18-month warranty.

How long does a leather strap last on a watch like the Trésor?

A quality leather strap, with vegetable tanning or shell cordovan, lasts an average of 3-5 years under moderate daily use conditions. Longevity depends on factors such as humidity, perspiration, sun exposure, and frequency of use. A well-maintained strap protected from extreme atmospheric agents develops a fascinating patina over time. It is possible to extend its life by replacing the inner lining or recreating the stitching when it shows signs of wear.
