What I'm asked about the Omega De Ville 434.10.40.20.01.001

What strap size does the Omega De Ville 434.10.40.20.01.001 take?

The Omega De Ville 434.10.40.20.01.001 needs 19 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Omega De Ville 434.10.40.20.01.001 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.

Can I put a leather strap on the Omega De Ville 434.10.40.20.01.001?

Yes, in 19 mm leather. On a 40 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the Omega De Ville 434.10.40.20.01.001?

A thin 19 mm alligator. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions

Is an aftermarket strap compatible with my Omega De Ville 434.10.40.20.01.001?

Yes, provided it measures exactly 19mm in width. Compatibility is not limited to genuine Omega straps, but it is essential to verify the precise measurement to avoid play or excessive pressure on the lugs.

How long does a leather strap last on a watch like the De Ville 434.10.40.20.01.001?

With proper maintenance (periodic conditioning, protection from moisture), an alligator or calf strap lasts 4-6 years of daily wear. Shell cordovan with vegetable tanning ages better and can last 7-10 years. Durability depends on exposure to perspiration, water and extreme temperatures.

The next step

The right strap isn't chosen. It is built, together.
