Strap for De Ville Co-Axial 38.7 GMT Stainless Steel / Grey / Bracelet

The Omega De Ville 4533.40.00 is equipped with a 20mm lug width. You can verify this by measuring the space between the case lugs using a digital caliper. This dimension is standard for all watches of this reference and ensures complete compatibility with dedicated straps.

The ideal strap is alligator leather in vegetable tanning, which combines formal elegance with the natural patina that develops over time. Crocodile leather offers a fine texture that perfectly complements the understated steel case. Alternatively, vegetable-tanned calf leather is a practical choice with comparable longevity.

Strap replacement requires removal of the lateral spring bars that lock the bracelet. Use a dedicated tool (spring bar tool) to compress the inner pin and free the lug from the case. Insert the new strap by aligning the holes with the pins and release. This is a delicate operation: if you are not confident, consult a qualified watchmaker.

Yes, any strap with a 20mm lug width is compatible with the De Ville 4533.40.00. You can find many ready-to-ship options online. For a complete artisanal experience, the Casati Milano atelier creates custom straps in vegetable leather with full customization of finishes.

Durability depends on the quality of the leather and its use. A well-maintained alligator or vegetable-tanned calf strap lasts 8-10 years in daily use. Casati Milano atelier offers an 18-month warranty on custom straps, and natural vegetable leather tends to improve with age, developing a fascinating patina.
