Frequently asked questions
What is the lug width of my Omega De Ville 434.25.34.20.55.002?
The lug width of this model is 16mm, a specific and non-standard dimension. It is measured internally between the two pins that house the strap, using a digital caliper positioned perpendicular to the case.
Which strap is most suitable for the Omega De Ville 434.25.34.20.55.002?
Black or dark brown dyed alligator is the choice most consistent with the elegant vocation of the De Ville. Alternatively, aged shell cordovan or vegetable-tanned calf offer personal patina over time. Avoid rubber straps or bright colours.
How do I change the strap on my 434.25.34.20.55.002?
Remove the old strap by extracting the pins from the lugs. Use a spring bar tool or dedicated tool to avoid scratching the case. Then insert the new 16mm strap by aligning the pins with the lug holes, ensuring they are perfectly seated.
Can I use an aftermarket 16mm strap on this Omega watch?
Yes, any strap with a 16mm lug width is compatible from a constructive standpoint. However, the choice must be aesthetically coherent with the dress-elegant nature of the model, preferring fine leathers and sober colours.
How long does a leather strap last on an Omega like the 434.25.34.20.55.002?
A quality artisanal alligator or shell cordovan strap lasts 3 to 5 years with moderate use (worn 3-4 times a week). Longevity depends on ambient humidity, perspiration and frequency of use. Periodic maintenance extends its lifespan.
