Frequently asked questions
What is the lug width of the Omega De Ville 424.20.37.20.03.001?
The lug width is 19 mm. It is measured by calculating the internal distance between the lug terminals where the strap attaches to the case. This width is characteristic of classic European watches in this size category.
Which strap do you recommend for the Omega De Ville 424.20.37.20.03.001?
Black alligator with an 18-karat yellow gold deployant represents the finest choice, creating chromatic coherence with the two-tone case. Alternatively, wine-colored shell cordovan or vegetable-tanned calf leather in medium brown offer versatility and aesthetic character over time.
How do you change the strap on the Omega De Ville 424.20.37.20.03.001?
The strap is attached via spring bars to the lugs of the case. Using a dedicated tool (spring bar tool), compress the internal spring of the bar, extract the previous strap, and install the new one. The operation requires care to avoid damaging the case's finishing.
Which aftermarket straps are compatible with the Omega De Ville 424.20.37.20.03.001?
Any strap with a 19 mm lug width is compatible. We recommend solutions in alligator, shell cordovan, or vegetable-tanned calf leather, preferably custom-made to ensure optimal proportions and precise construction tolerances.
How long does a leather strap last on the Omega De Ville 424.20.37.20.03.001?
A quality leather strap, worn regularly, maintains structural integrity for 3-5 years. Shell cordovan and alligator can exceed 7-8 years with proper care. Longevity depends on frequency of use, the tanning method applied, and environmental exposure (humidity, direct sunlight).
