Strap for Mini Trésor Quartz 26 Stainless Steel - Diamond / White - Rose / Toile de Jouy - Double Tour

The lug width of the Trésor 428.17.26.60.04.003 is exactly 13mm. This non-standard dimension requires straps built to specification, as industrial production focuses on sizes of 10mm, 12mm, 14mm or larger. Always verify with a digital caliper the distance between the inner shoulders of the lugs.

Alligator is the most aesthetically coherent choice: the parallel grain does not compete with the case's sobriety and adds tonal depth. Vegetable-tanned calf is the most interesting tonal alternative for those seeking evolved patina over time. Shell cordovan offers rigidity and density, while nylon NATO ensures practical versatility while maintaining a refined profile.

The Trésor uses fixed lugs (not spring bars). To replace the strap, you must remove the lug nuts with a specialized tool or at an Omega service center. This procedure cannot be performed yourself unless you possess the correct equipment. Milano Straps and the Casati Milano atelier offer both compatible straps and mounting services by appointment.

Yes. Milano Straps offers a dedicated collection of straps for 13mm lugs, including models in alligator, calf, shell cordovan and technical rubber. All straps are built to specification to ensure structural compatibility. The Casati Milano atelier also offers bespoke creation services with customization of leathers and dimensions.

Durability depends on the material and usage. A quality alligator strap, with regular maintenance (periodic cleaning, drying after moisture exposure), offers 5-7 years of life. Shell cordovan tends to last longer thanks to its superior density. Vegetable-tanned calf requires greater attention to humidity but acquires prized patina. Technical rubber has variable durability depending on thickness and composition.
