Strap for De Ville Byzantium Co-Axial 33.4 Co-Axial Stainless Steel / Silver / Russia

The lug width of the 7802.30.32 is 20 mm. This measurement corresponds to the distance between the pins that attach the strap to the case lugs. To verify, measure the attachment holes on the case directly or consult the Omega warranty booklet, where the specification is always listed. Milano Straps confirms compatibility before shipment.

High-grade alligator is the top-tier choice, featuring authentic granulated texture and exclusive patina. Shell cordovan offers natural compactness and noble aging. Vegetable-tanned calf is the ideal compromise: versatile, durable, and sophisticated, suitable for both formal and semi-formal contexts. It depends on your personal style and daily wear conditions.

Remove the old strap by unscrewing or lifting the pins that pass through the case lugs (generally with a small fine-tipped screwdriver). Insert the new pins into the new strap, then secure everything into the lugs. If you are unsure, a professional watchmaker can complete the operation in 10 minutes. Milano Straps provides straps pre-fitted with lugs to facilitate DIY installation.

Absolutely yes. A 20 mm aftermarket strap is fully compatible, provided the lug width is measured correctly. Milano Straps offers dozens of models in this width, from alligator to calf, with customization options in stitching thread color and initials. Artisanal quality is guaranteed and comparable to luxury brand straps.

A high-quality leather strap (alligator, cordovan, calf) lasts an average of 3-5 years with moderate daily use, depending on climate, cleaning frequency, and natural wrist wear. Shell cordovan tends to last longer thanks to its compact molecular structure. Vegetable-tanned leather develops protective patina over time. Milano Straps offers an 18-month warranty and recommends regular maintenance with specific balms to extend strap life.
