Frequently asked questions
What is the lug width of the Omega De Ville 424.23.40.20.10.001?
The lug width is exactly 20 mm. This measurement should be taken between the two lugs on the side of the case. It is essential to ensure compatibility with any aftermarket strap.
Which strap would you recommend for the Omega De Ville 424.23.40.20.10.001?
For this two-tone gold and steel case, we recommend black or brown alligator in vegetable tanning, or fine-grained calf leather in cognac or bordeaux. Shell cordovan is a bold choice for those who desire a natural shine. Avoid overly light shades that would dilute the visual impact of the gold.
How do you change the strap on this Omega?
Use a springbar tool to remove the pins from the attachment bar. Insert the tool into the lug hole, gently lift to disengage the spring, and the strap will detach. For installation, repeat the procedure in reverse. If you are not confident, consult a certified watchmaker.
Can I use an 18 or 22 mm strap?
No. The 20 mm lug width is specific to this model. An 18 mm strap would be unstable between the lugs; a 22 mm strap would not fit at all. It is crucial to respect the exact measurement.
How long does a leather strap last on an Omega De Ville?
Durability depends on the material and usage. A medium-grain calf leather in vegetable tanning lasts 3–5 years with daily wear. High-quality alligator can last 5–8 years. Shell cordovan is the most durable, lasting up to 10 years. Regular maintenance (cleaning and conditioning) significantly extends the life of the strap.
