The De Ville 424.55.33.20.55.009 (aka: 42455332055009), seen from the bench

The De Ville belongs to Omega's elegant collection dedicated to city watches. It is equipped with the automatic Calibre 2500 with co-axial escapement and chronometer certification, featuring indication of hours, minutes, seconds and date. The co-axial movement reduces the friction between the traditional watchmaking components.

Frequently asked questions

What is the lug width of the De Ville Prestige 424.55.33.20.55.009?

The lug width is exactly 18mm. This measurement is specific to the model and proportioned to the 32.70mm case diameter. To verify it, measure the distance between the two attachment points of the original bracelet.

Which strap is most suitable for the Omega De Ville in yellow gold?

Vegetable-tanned alligator is the canonically correct choice for this dress watch: the natural grain complements yellow gold and the patina evolves over time. Alternatively, vintage calf or shell cordovan produce extraordinary aesthetic effects with minimalist elegance.

How do I change the strap on my De Ville 424.55.33.20.55.009?

Use a spring bar removal tool to gently extract the spring bar attachments from the bracelet or case lugs. Insert the new strap into the same attachment points, ensuring the lug passage is perpendicular. If you are uncertain, entrust the task to a professional to avoid damage to the case.

Are aftermarket 18mm straps really compatible with the De Ville?

Yes, any strap with 18mm lug width is compatible. Always verify that the spring bar attachments are identical (diameter, length). Straps from reliable brands guarantee construction consistent with Omega standards and superior longevity.

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

A quality alligator or calf strap lasts 5–7 years with daily use and appropriate maintenance (occasional cleaning, drying after water contact). Shell cordovan and vegetable-tanned materials tend to last slightly longer thanks to superior structural density.
