Frequently asked questions

What is the lug width of my Omega De Ville 4374.11.00?

The Omega De Ville 4374.11.00 is fitted with 18mm lugs. This width is determined by the distance between the pins that secure the strap to the terminals of the 36.50mm case. Always verify by measuring directly between the inner pins to avoid errors.

Which strap material is most suitable for the two-tone De Ville?

To maintain the formal elegance of the two-tone case in yellow gold and steel, we recommend alligator in dark shades (brown, burgundy) or vegetable-tanned calfskin that develops patina over time. Avoid synthetic materials: they would clash with the dignity of the precious case.

How do I change the strap on my Omega De Ville 4374.11.00?

Position the watch with the dial facing downward. Locate the small button or lever beneath the case terminals. Gently press the button from one side to push the pin out, then remove the old strap. Insert the new strap and snap the pin back into place. If unsure, contact an authorized Omega service center.

Can I use an aftermarket strap compatible with the Omega De Ville?

Absolutely. Any strap with 18mm lug width is compatible with the De Ville 4374.11.00. High-quality artisanal straps often surpass integrated bracelets in terms of longevity and patina development over time. Choose noble leathers such as alligator, shell cordovan, or vegetable-tanned calfskin.

How long does a leather strap last on the Omega De Ville?

Durability varies depending on material and use. Quality alligator lasts 4-6 years with regular maintenance. Vegetable-tanned calfskin can last 3-5 years before requiring replacement, while developing a fascinating patina. Shell cordovan, rarer, can exceed 7 years. The Casati Milano warranty covers 18 months on all bespoke straps.
