Strap for De Ville Co-Axial 35 Stainless Steel / Silver / Bracelet

The lug width of the De Ville 4561.31.00 is 20 millimetres. This measurement refers to the distance between the two spring bars that pass through the lateral lugs of the case. You can verify it easily without removing the bracelet by using a digital caliper and measuring the distance between the two openings (lugs) on the side of the case.

The Omega De Ville 4561.31.00, being an elegant and classical timepiece, pairs ideally with straps in alligator, tanned calf leather or shell cordovan. For everyday use, calf leather offers the best compromise between comfort and aesthetics. For formal occasions, alligator with its geometric grain is the most sophisticated choice. Vegetable tanning gives the timepiece an authentic vintage character, as this watch dates back to the nineties.

The De Ville 4561.31.00 features an integrated stainless steel bracelet. To replace it with a replacement strap, you need to use a spring bar remover (forked tool) to extract the two spring bars that secure the bracelet to the lateral lugs. Once the spring bars are removed, the bracelet slides off and the new strap can be inserted by aligning its ends to the lugs. The operation requires care to avoid scratching the polished stainless steel case.

Yes, any strap with a 20mm lug width is technically compatible. However, it is important to consider the strap thickness (the ends must fit correctly in the lugs) and the total length (it must allow easy fastening on the wrist). Handcrafted straps from Milano Straps are built specifically for this measurement and allow length customization to ensure maximum comfort.

The durability of a leather strap depends on the intensity of use and the type of tanning. A high-quality handcrafted calf leather strap, worn daily, maintains excellent aesthetics for 2-3 years before showing visible signs of wear (creasing, slight peeling). Vegetable tanning ages more slowly and can remain in good condition for 3-4 years. Alligator, being a very dense leather, can last even 5-6 years. The 18-month warranty offered by Casati Milano covers any manufacturing defects.
