What I'm asked about the Omega De Ville 434.20.40.20.02.001

What strap size does the Omega De Ville 434.20.40.20.02.001 take?

The Omega De Ville 434.20.40.20.02.001 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 434.20.40.20.02.001 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 434.20.40.20.02.001?

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 434.20.40.20.02.001?

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.

The De Ville 434.20.40.20.02.001, seen from the bench

The Omega De Ville 434.20.40.20.02.001 represents the contemporary evolution of a collection born in 1969. This model combines Sedna Gold, Omega's proprietary red gold alloy, with stainless steel in a two-tone case design. It features the Omega 8800 caliber with Co-Axial Escapement, a 40mm case diameter, and 19mm lug width. Water resistance is 100 meters, and the dial includes a date window at 3 o'clock. The caseback is sapphire crystal, revealing the movement with Breguet hairspring and gold rotor.

Frequently asked questions

Which strap material pairs best with this two-tone Sedna Gold and steel case?

Dark brown alligator with fine grain is the classic choice that does not compete with the two-tone alloy. Shell cordovan, thanks to its density and natural patina, creates aesthetic harmony with the rose gold. For construction simplicity, smooth calf in brown or black offers pure proportions. Polished black leather with a steel deployant clasp is the minimalist solution to transform it into a formal dress watch.

Can I use an aftermarket 19mm strap on this model?

Yes, provided it is certified for 19mm lugs. Not all artisans produce in this specific size: it is a niche between the 18mm of smaller cases and the standard 20mm. Milano Straps offers compatible straps customizable in leather, color, and length.

How long does a natural leather strap last on a daily-wear wristwatch?

Under normal conditions, 18–36 months. Durability depends on the tanning method (vegetable tanning ages better but is more delicate), frequency of use, and exposure to moisture and sunlight. Shell cordovan lasts longer thanks to its density. A strap in good condition can be restored (recoloring, clasp replacement) rather than discarded.

The next step

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