Strap for De Ville Co-Axial 41 Chronoscope Red Gold / Black

The lug width of the Omega De Ville 4656.50.31 is 20mm. This measurement represents the internal distance between the case lugs and is crucial for the compatibility of any aftermarket strap. It is essential to verify that the strap you wish to purchase is actually sized for 20mm, as straps of different sizes would damage the case.

A black alligator with a matching rose gold deployant clasp represents the most coherent choice from both aesthetic and constructive perspectives. The regular texture of alligator naturally complements the solidity of the rose gold case. Excellent alternatives include a vegetable-tanned calf in honey brown tones, or an aged shell cordovan in burgundy, which develops a unique and personal patina over time.

Changing the strap on the De Ville 4656.50.31 requires the use of a specific tool called a spring bar tool. Position the tool under the metal lugs (spring bar) that secure the current strap, gently push inward to compress the spring, then remove the used strap. Insert the new strap into the lugs, ensuring that the spring bar locks completely. If you are not confident with this operation, replacement at a professional watchmaker is always recommended, especially for a luxury piece like this.

Yes, straps in the 20mm size are compatible with the De Ville 4656.50.31. However, geometric compatibility requires attention: the De Ville's lugs feature an internal step that requires a strap with appropriate constructive profile. At Milano Straps you will find a curated selection of 20mm straps specifically chosen to ensure structural and aesthetic compatibility with this Omega model, available both ready-made and customizable with the Casati Milano atelier.

The longevity of a leather strap depends on the quality of the leather, frequency of wear, and exposure to weather elements. An alligator or calf of excellent quality, worn daily, maintains structural integrity for 2-4 years before requiring replacement. Shell cordovan, thanks to its superior density, can last 5-7 years. Vegetable tanning ensures greater longevity compared to modern chemical tanning methods. Keeping the strap away from direct heat sources and excessive moisture significantly extends its lifespan. The Casati Milano atelier provides an 18-month warranty on all handcrafted straps produced.
