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

The lug width is 20mm. This is the distance between the spring bar holes (metal lugs) measured from inside to inside. It is a standard size for many medium to large Omega timepieces, allowing good versatility when changing straps.

It depends on use and personal taste. For formal occasions we recommend black or dark brown alligator; for elegant everyday wear, vegetable-tanned calf leather; for those seeking sport-elegant versatility, a burgundy shell cordovan or grey-navy NATO. The important thing is that the strap is 20mm wide and equipped with a deployant clasp.

The strap is changed using a spring bar tool. Insert the flat end of the tool into the spring mechanism under the lug from the outside of the case, press gently inward and lift the spring bar. Repeat on the other side. Insert the new strap, ensuring the spring bars lock perfectly into the lugs.

Yes, provided they are certified for 20mm lug width and the thickness conforms (generally 4-5mm for a dress watch). We recommend verifying dimensions with the supplier before purchase. Artisanal straps from Milano Straps are built specifically for this size.

Durability depends on the material and use. Everyday calf leather lasts 18-24 months; quality alligator 2-3 years; shell cordovan 3-4 years or more. Humidity, perspiration and sun exposure accelerate aging. Artisanal straps from Casati Milano include 18-month warranty and can be professionally restored.
