Strap for De Ville Co-Axial 37.5 Stainless Steel / Black / Bracelet

The lug width of the De Ville 4531.50.00 is 20mm. This is the distance between the lug pins that hold the strap on the case. Verify with a digital caliper by positioning the tips between the two contact points: the measurement must be 20.00mm to guarantee perfect compatibility.

Black alligator or deep brown alligator is the ideal choice: the fine grain reflects the understated elegance of the case, and aging develops a refined patina. For those who prefer daily robustness, a satin calf or vegetable-tanned cognac leather work excellently. We advise against NATO and rubber: the dress aesthetic of the De Ville does not tolerate sporty transformations.

Obtain a spring bar tool or consult a professional watchmaker. Position the tool between the case and the pins that hold the strap, push gently to remove the pin from one side, and release the strap. Repeat on the other side. Insert the new strap by aligning it with the holes and push the pins back with the same tool until the click closes. Verify that the strap has no play.

Yes, any strap with a 20mm lug width is physically compatible with the De Ville 4531.50.00. However, verify the final dimensions (width) so that the keeper does not protrude beyond the case. The quality of the leather, the buckle and the craftsmanship will determine whether the aesthetic result maintains the dignity of the watch.

A professional-quality alligator or calf leather strap lasts 3-5 years with regular wear. A vegetable-tanned leather can exceed 5 years, developing a fascinating patina. Durability depends on frequency of use, humidity and maintenance (periodic cleaning with soft dry cloths). Milano Straps guarantees 18 months on the artisanal strap.
