Can the strap on the Omega De Ville 431.63.41.21.13.001 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Frequently asked questions

Which strap is best for the Omega De Ville 431.63.41.21.13.001?

For the De Ville 431.63.41.21.13.001 in rose gold, we recommend straps in dark brown or cognac alligator , reflecting the tradition of classic leather goods while maintaining chromatic cohesion with the precious metal. Vegetable-tanned calfskin represents an ideal contemporary alternative for those who prioritize breathability and natural patina development over time. Shell cordovan constitutes the most discerning choice for those seeking a strap that develops distinctive character marks, although it requires greater maintenance attention. A deployant clasp remains the most appropriate security system for this type of case.

What aftermarket strap can I use for the 431.63.41.21.13.001?

The Omega De Ville 431.63.41.21.13.001 accepts any strap with a lug width of 20mm, regardless of manufacturer. Milanostraps.it offers a curated collection of 20mm straps in various leathers and finishes, customizable according to your needs. Geometric compatibility is guaranteed: simply verify that the passant is not too wide, a rare issue with professional straps but possible with generic manufacturers. For rose gold, contrasting finishes (cognac, black, English green) create balanced aesthetic contrasts.

What is the lifespan of a leather strap for the 431.63.41.21.13.001?

A quality leather strap, used under normal conditions (not worn daily), maintains structural integrity for 4-6 years. Vegetable tanning develops more visible but characteristic wear, transforming the strap into an object with its own aesthetic history. Shell cordovan extends this lifespan to 8-10 years thanks to superior fiber density. The determining factor is exposure to humidity and perspiration: a strap worn constantly during summer will deteriorate more rapidly than one used occasionally in dry environments. Casati Milano provides straps with an 18-month warranty, covering manufacturing imperfections but not natural wear.
