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

The lug width of the De Ville 4533.31.00 is 20mm, measured between the inner shoulders of the lugs. This dimension is precise and does not allow for variations: an 18mm strap would create visible gaps, while a 22mm strap would force the fit. Milanostraps provides straps cut exactly at 20mm to guarantee perfect adaptation to the original lugs.

Alligator remains the most authentic choice for the De Ville: its uniform grain naturally complements the architectural simplicity of the case, and the leather develops a warm patina that amplifies the watch's story over time. Shell cordovan offers a structured texture for those who prefer greater rigidity. Vegetable-tanned calf represents a more versatile alternative with a surface that ages visibly.

The De Ville is fitted with spring bars and pins (or screw-down lugs, depending on the year of production). To replace the strap: 1) remove the pins from the lugs using a dedicated tool (spring bar tool); 2) extract the old strap; 3) insert the new strap ensuring that the spring bars are correctly aligned with the lugs; 4) press the pin until you hear a click. We recommend having the operation performed by a qualified watchmaker if you do not have experience with the tools.

Yes, provided the strap is built to measure at 20mm and is compatible with the lug width. Milanostraps straps are designed and cut specifically to fit the proportions of the De Ville without compromise. The quality of the leather and the finishing must respect the technical and aesthetic standard of the Omega case to maintain the overall harmony of the timepiece.

A quality alligator or shell cordovan strap, subjected to regular maintenance (gentle cleaning, conditioning every 6-12 months), can last 5-8 years before requiring replacement. Durability depends on frequency of use and environmental conditions (humidity, sun exposure). A vegetable-tanned calf ages more rapidly and visibly, offering more frequent replacement as part of its evolutionary charm. Milanostraps offers an 18-month warranty on all made-to-measure straps.
