Strap for De Ville Trésor 36 Stainless Steel / White Roman / Fabric

The lug width of the Trésor 428.17.36.60.04.001 is 18mm. This dimension represents the distance between the two attachment pins of the case and determines compatibility with replacement straps. The 18mm is a classic standard, historically linked to vintage Seamaster models, and requires careful attention when selecting a strap to maintain aesthetic balance between case and bracelet.

The ideal material depends on intended use. For a choice coherent with the Seamaster heritage, medium brown alligator (Cognac) offers a fine grain texture that does not compete visually with the dial. Vegetable-tanned calf creates a patina that develops over time. For nautical contexts, vulcanized FKM rubber maintains water resistance. A cotton NATO strap introduces a casual dimension for weekends.

The strap is changed by removing the lateral spring bars (pins) that secure the current strap to the case lug pins. Use a specific tool (spring bar tool) to avoid scratches. Once the bars are released, the old strap detaches easily. Insert the new spring bars into the replacement strap and secure them to the case lugs, ensuring they are locked correctly. The operation takes just a few minutes and does not require watchmaking skills.

All straps with an 18mm lug width are compatible with the Trésor 428.17.36.60.04.001. Options include alligator, calf, shell cordovan, suede, cotton NATO, FKM rubber, and even woven straps. Technical compatibility is universal; the choice depends on desired aesthetics and context of use. MilanoStraps offers a collection of customizable 18mm straps in various sizes, colors, and stitching finishes.

A quality leather strap, such as those made by Casati Milano, has an average lifespan of 3-5 years with daily use, provided minimal maintenance (avoid prolonged water exposure, store in a dry environment). Longevity depends on the type of leather: alligator and shell cordovan tend to age better and develop a desirable patina over time. A vulcanized rubber strap has a longer lifespan (5-7 years), especially if used in humid or nautical environments. Replacement is nonetheless economical and does not require watchmaking intervention.
