Frequently asked questions
What is the exact lug width of the Omega Trésor 428.18.36.60.11.002?
The lug width of the Trésor 428.18.36.60.11.002 is 18 millimetres. This is the functional measurement, taken from the inner side of one lug to the other in parallel to the dial. Always verify the lug width before ordering a strap, as it is the critical parameter for compatibility.
What is the best strap material for the Omega Trésor 36mm?
For the Trésor 36mm we recommend three choices in order of sophistication: dark brown alligator (minimalist elegance concentrated), cognac vegetable-tanned calf (patina evolving over time, artisanal humanity), burgundy shell cordovan (extraordinary durability and crystalline appearance). The choice depends on intended use and dial colour. For warm seasons, articulated waxed canvas remains a valid alternative.
How do you change the strap on a watch with 18mm lugs?
The change requires a specific tool: a spring bar tool (instrument with rounded tip). Position the watch horizontally, insert the tip under the pin (spring bar) that supports the lug, apply light pressure until the internal spring releases, extract the pin, remove the old strap, insert the new one aligning it perfectly to the lugs, and reinsert the pin until the locking click. Verify that the passant is perfectly adherent to the lug.
Is there a quality aftermarket strap for the Omega Trésor 428.18.36.60.11.002?
Yes. Italian artisanal 18mm straps are 100% compatible with the Trésor. Milanostraps offers a collection dedicated to 18mm straps, made by specialized craftsmen with noble leathers (alligator, calf, shell cordovan, canvas). Casati Milano also creates bespoke solutions after personal consultation, with leather selection and customisations (initials, thread colour).
How long does a leather strap last on a watch worn daily?
A quality leather strap, with vegetable tanning and artisanal construction, typically lasts between 18 and 36 months of daily use, depending on exposure to sun, humidity and perspiration. Shell cordovan lasts longer (up to 4-5 years) thanks to the density of the raw material. Alligator lasts 2-3 years if subjected to average conditions. Casati Milano offers an 18-month warranty on all straps produced.
