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

The lug width of the Omega De Ville 4831.51.31 is 16mm. This measurement is specific to the model and is determined by the integrated lug architecture. To verify strap compatibility, it is essential to measure the space available between the lateral lugs using a digital caliper or millimeter ruler.

For the De Ville 4831.51.31 we recommend alligator for maximum formality, shell cordovan for those who desire a patina that evolves over time, and vegetable-tanned calf leather for a balance between elegance and versatility. The choice depends on intended use: for formal settings alligator is unmatched, while shell cordovan is ideal for those wanting a watch that visibly ages gracefully.

Changing the strap on the De Ville 4831.51.31 requires a spring bar tool to remove the elastic pins that secure the strap to the lugs. Position the watch securely, insert the tool into the small hole beneath the lug to compress the spring bar, remove the old strap and insert the new one by clicking the pin into position. We recommend performing this operation on a soft surface to protect the case.

A 16mm strap is dimensionally compatible with any watch that features the same lug width. However, the De Ville's integrated lug attachment has a specific architecture: always verify that the new strap respects the depth and geometry of the space available between the lugs, as some straps may not fit perfectly if designed for different lug configurations.

The lifespan of a leather strap depends on the tanning method and usage. A quality alligator strap typically lasts 3-5 years with daily wear; shell cordovan can last 4-7 years thanks to its inherent durability; vegetable-tanned calf varies from 2-4 years. Exposure to humidity, perspiration and UV rays shortens strap lifespan. Proper maintenance and rotating between multiple straps significantly extend overall durability.
