Strap for De Ville Hour Vision Master Chronometer Sedna Gold / Silver / Bracelet

The lug width of the De Ville 433.50.41.21.02.001 is 20mm. This dimension corresponds to the space between the case lugs where the strap is attached. To verify compatibility, measure with a digital caliper the distance between the two lugs at the widest point of the attachment.

Alligator is the most natural choice: the regular texture and fine grain perfectly complement the refinement of Sedna Gold. Cognac brown in calf leather creates chromatic harmony, while black alligator offers maximum contrast and formality. Navy blue is not recommended, as it contrasts excessively with the warmth of rose gold.

Remove the old strap using a spring bar tool, gently prying the small pins that snap laterally. Insert the new strap by aligning the holes with the lugs, pressing until it clicks. If you are not confident, entrust the task to a professional watchmaker to avoid damage to the case.

Yes, provided it respects the 20mm lug width. On milanostraps.it you will find artisanal compatible straps in alligator, calf, shell cordovan and vegetable tanning, all tested for this specific size. The Casati Milano atelier also offers complete customization with sizes, initials and stitching thread upon request.

Durability depends on the material and usage. An alligator or shell cordovan strap, with proper maintenance (avoiding excessive moisture and abrasive dirt), lasts 5-10 years. Calf leather has a slightly shorter lifespan, 3-7 years. Vegetable-tanned leather, more delicate, requires greater care but ages beautifully. Milano Straps guarantees 18 months on Casati Milano straps, with the possibility of replacements in case of manufacturing defects.
