Strap for De Ville Hour Vision Co-Axial Stainless Steel / Black

The Omega De Ville 431.33.41.21.01.001 has a lug width of 20mm. This measurement represents the distance between the lugs on the case where the strap attaches. It is essential to order straps specifically sized at 20mm to ensure a perfect fit without lateral play. A strap of different size (18mm, 22mm) will not mount correctly, creating instability on the wrist.

The best strap depends on your use and personal style. Vegetable-tanned alligator in black or dark brown is the most coherent choice with the De Ville's urban aesthetic, thanks to its regular texture that complements the case's clean lines. For those seeking versatility, medium brown vegetable-tanned calf offers flexible pairing options. For humid or sports environments, vulcanized FKM rubber maintains harmonious proportions while ensuring absolute resistance. NATO is discouraged as its sporty character contrasts with the elegant identity of this model.

The change requires a specific tool: a spring bar tool. Position the watch so that the lug is parallel to the table, insert the tool into the slot next to the spring bar, gently push downward until the spring bar retracts, then remove the old strap. Repeat the procedure on the opposite side. To mount the new strap: align the hole of the first lug with the spring bar, insert it with the tool, then apply pressure until the spring bar clicks into position. Repeat on the other side.

Any strap with a 20mm lug width is compatible with the De Ville 431.33.41.21.01.001. Always verify that the seller certifies exactly 20mm as the lug width. On milanostraps.it you will find a selection of artisanal 20mm straps in various materials: alligator, calf, shell cordovan, rubber. Each strap can be customized in size, initials, and stitching thread color for a perfect match with your watch.

The durability depends on the material, use, and maintenance. A quality alligator or calf strap, with vegetable tanning, typically lasts 3-5 years with moderate daily use. Shell cordovan, due to its natural density, can last 5-7 years. Vulcanized rubber has a longer lifespan (8-10 years) but requires regular cleaning. To extend the life, avoid prolonged water immersion, protect it from excessive perspiration, and occasionally apply conditioning products specifically designed for leather. Straps made by Casati Milano include an 18-month warranty and can be professionally regenerated if necessary.
