Strap for De Ville Trésor 36 Canopus Gold / Aventurine Roman / Alligator

The Omega Trésor 428.58.36.60.53.001 features 18 millimeter lugs. This measurement is standard for classic small watchmaking and requires straps built to millimeter precision. There is no tolerance margin: a 17 or 19 millimeter strap will not fit correctly into the white gold lugs without creating friction.

Alligator represents the most authoritative choice for the Trésor in white gold, thanks to its natural grain that amplifies the perception of quality. Shell cordovan offers a patina that evolves over time, creating a chromatic dialogue with the gold. Vegetable-tanned calf is ideal for those seeking softness and daily versatility. The choice depends on intended use and personal aesthetics.

The strap is replaced using a spring bar remover to release the internal lug. Insert the tool into one of the holes in the lug, apply gentle lateral pressure, and the lug retracts. Once free, the strap slides out of the lug. Proceed the same way on the other side. The operation requires delicacy to avoid scratching the gold.

Yes. The 428.58.36.60.53.001 uses standard 18mm specifications compatible with any strap constructed to this measurement. Straps in alligator, cordovan, calf, and rubber from artisanal manufacturers often offer construction quality superior to OEM straps. The important thing is to verify that the lugs are correctly graduated to avoid forcing the insertion.

Durability depends on intensity of use and material. A quality alligator strap, worn daily, maintains structural integrity for 4-6 years. Shell cordovan, more robust, can exceed 8 years. Vegetable-tanned calf, more delicate, lasts 3-5 years. The Casati Milano atelier offers an 18-month warranty on custom straps, with the possibility of leather regeneration through sanding and re-dyeing.
