Frequently asked questions
What is the lug width of the Omega Trésor 428.58.26.60.04.002?
The lug width of the Trésor 428.58.26.60.04.002 is 13mm, measured between the internal attachment points of the lugs. This measurement is specific to this family of timepieces and ensures a perfect fit between case and strap without excess material on the sides.
Which strap is recommended for the Trésor 428.58.26.60.04.002?
Vegetable-tanned alligator and noble calf leather are the ideal choices to enhance the elegance of the Moonshine Gold. Alligator offers a natural shield pattern that amplifies the perception of luxury, while calf combines formal and everyday versatility with an exceptionally fine grain. For a narrative approach through time, shell cordovan develops a rich patina that dialogues beautifully with the case.
How do I change the strap on my Omega Trésor 428.58.26.60.04.002?
Strap replacement is performed by removing the spring bars from the original lugs using a dedicated tool (spring bar tool). Align the new strap (13mm) with the case attachments, insert the spring bars, and snap the strap into position. If you are not confident, the Casati Milano atelier offers a strap-change service with personal consultation.
Can I use an aftermarket strap on a 26mm Omega Trésor?
Yes, as long as the lug width is exactly 13mm. Any strap with this specification will be compatible with the 428.58.26.60.04.002. On milanostraps.it you will find a collection of 13mm straps in various materials (alligator, calf, shell cordovan, NATO) ready to ship and customizable in size, initials, and stitching thread color.
How long does a leather strap last on a 26mm Omega women's watch?
Durability depends on the material and use. A high-quality alligator or calf strap with vegetable tanning typically lasts 3-5 years with daily wear. Shell cordovan is more resistant, developing a patina without structural deterioration. NATO straps in nylon have superior longevity (5-10 years). The Casati Milano atelier provides an 18-month warranty on all bespoke straps.
