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

The lug width of the Omega Trésor 428.58.36.60.55.001 is 18 millimetres. This measurement is specific to this model and is not interchangeable with 20mm or 16mm straps. Always verify compatibility by measuring with a digital calliper positioned between the case lugs where the strap is inserted.

The ideal strap depends on intended use and personal preference. For formal occasions, we recommend natural alligator or vegetable-tanned calf in brown or black tones, which enhance the white gold case. Shell cordovan introduces elegant texture and a patina that evolves over time. For daily versatility, a cotton nato or structured rubber strap offer practicality while maintaining refined proportions.

Changing the strap requires a specific tool (spring bar pusher) to remove the attachment pins from the lugs. Position the watch on a stable surface, identify the two lateral pins at the lugs, press the pusher perpendicularly to extract them, remove the worn strap and insert the new one by aligning the seats. Proceed with care to avoid damage to the case. If not confident, entrust the task to a professional watchmaker.

Yes, provided the lug width is exactly 18mm. Quality artisanal straps (crafted in alligator, calf or shell cordovan with bespoke construction) are fully compatible and indeed offer superior finish and longevity compared to generic catalogue straps. It is important to always verify dimensions before purchase.

The durability of a natural leather strap depends on the tanning method, usage and maintenance. Well-crafted vegetable-tanned calf lasts 3-5 years with daily wear. Shell cordovan reaches 6-8 years thanks to its fibrous robustness. Alligator varies from 4 to 7 years. With proper maintenance (occasional cleaning, protection from excessive moisture, alternation with other straps), durability is significantly extended.
