Frequently asked questions

What is the lug width of the Omega Trésor 428.55.26.60.04.001?

The lug width is 13mm. This measurement represents the standard for Trésor ladies' watches and defines the space between the two metal lugs where the strap is housed. Always measure from center to center of the lugs to verify exact compatibility with a new strap.

Which strap is best suited for the Omega Trésor 428.55.26.60.04.001?

Alligator in cognac, white, or black tones is the most coherent choice with the Moonshine Gold case. Alternatively, vegetable-tanned shell cordovan offers a pronounced texture and a patina that evolves over time, amplifying the aesthetic value of the piece. Avoid synthetic fabric straps that undermine the luxurious nature of the watch.

How do I change the strap on the Omega Trésor?

Use a spring bar tool to gently push the spring contained in each lug inward, freeing the strap from the case terminals. Replace with the new strap ensuring that the lugs are perfectly aligned. Never force the lugs, as this may damage them. If you are unsure, consult a qualified watchmaker.

Can I use an aftermarket strap on this model?

Yes, provided the lug width is exactly 13mm. Verify compatibility by measuring the distance between the lugs. High-quality straps, such as natural alligator or vegetable-tanned shell cordovan, are recommended to enhance the Moonshine Gold case and ensure long-lasting durability. Avoid straps made from synthetic or poor-quality materials.

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

A strap made from high-quality alligator or shell cordovan has an average lifespan of 3-5 years with regular use and proper maintenance. Longevity depends on exposure to moisture, UV rays, and how intensively the watch is worn. <a href="https://milanostraps.it/pages/termine-glossario/concia-vegetale">Vegetable tanning</a> ages gracefully, developing a rich patina that increases the aesthetic value of the piece over time.
