Strap for De Ville Prestige Co-Axial 36.5 Red Gold / Diamond

The lug width is 20mm. This dimension is determined by the proportion of the 36.5mm diameter case and is not interchangeable with other Omega models such as the Seamaster (18mm) or Aqua Terra (22mm). Measuring correctly with a digital calliper the internal space between the lug shoulders ensures a compatible strap.

African alligator or vegetable-tanned calf are the ideal tonal choices. Both develop a patina that complements the chromatic evolution of rose gold over time. For formal austerity, a vegetable-tanned black calf maintains elegant proportions. For versatility, a mercerized cotton NATO transforms the De Ville into a casual timepiece without visually weighing it down.

The strap is removed using a spring bar tool to compress the internal elastic pin of the lug. Position the tool in the side opening of the lug, push the pin inward, remove the old strap. Reverse the procedure with the new strap, ensuring that the internal shoulders align perfectly with the 20mm lug width. We recommend this operation be performed by a professional watchmaker to avoid damage to the case.

Yes, any strap with a 20mm lug width is mechanically compatible. Aesthetic compatibility depends on your personal taste, but we recommend quality materials (alligator, shell cordovan, vegetable-tanned calves) that respect the aesthetic dignity of the rose gold case and the compact proportions of the model.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) worn 5-6 days weekly maintains structural integrity for 3-4 years. Actual durability depends on exposure to moisture, heat, stitching wear and maintenance. With periodic care (gentle cleaning, drying, occasional nourishing treatments) it is possible to extend the life to 5 years. Milano Straps offers an 18-month warranty on custom production.
