Strap for De Ville Prestige Co-Axial 36.8 Red Gold / Blue / Bracelet
Takes 19 mm straps. Verified lug width, the straps that fit this model, and answers to the most common questions.
Lug width
Frequently asked questions
What is the lug width of the Omega De Ville 424.50.37.20.03.002?
The lug width is exactly 19 mm. This specific dimension was chosen by Omega to maintain balanced proportions on the 36.80 mm diameter case. An 18 mm or 20 mm strap will not fit correctly: the spring bar would be too tight or too loose. Always verify the measurement with a digital caliper between the two internal lugs of the case.
What strap do you recommend for this rose gold De Ville?
Dark brown or cognac alligator is our top recommendation: it mirrors the warm tone of the 18k rose gold without competing visually. Vegetable-tanned calf leather is the most versatile alternative, with a patina that evolves over time. For formal elegance, burgundy shell cordovan creates natural harmony with the case. We advise against NATO straps: they contrast the sophisticated construction of this Master Chronometer movement.
How do I change the strap on the De Ville 424.50.37.20.03.002?
Omega fitted this model with a deployant clasp (if supplied with the original strap) or a straight keeper. Use a spring bar tool to extract the metal pins that secure the strap to the lugs. Position the tool on the pin, push toward the center of the case, and the strap releases. Request a strap with compatible spring bars, or contact Casati Milano for bespoke customization.
Are there aftermarket straps compatible with this model?
Yes. On milanostraps.it you will find a dedicated selection of 19 mm artisanal straps, ready for shipment. All are compatible with the lugs of the Omega De Ville 424.50.37.20.03.002. They can be customized in size, initials, and choice of stitching thread. For in-depth consultation and made-to-measure creations, Atelier Casati Milano offers bespoke service with 18-month guarantee.
How long does a leather strap last on this watch?
A high-quality alligator or calf leather strap lasts on average 3–5 years with daily wear and regular maintenance (drying after humidity exposure, periodic cleaning with a soft brush). Shell cordovan, thanks to its density, can exceed 5 years. The developed patina is an added value, not deterioration. Casati Milano guarantees its straps for 18 months; beyond this period, replacement of the metal spring bar is always possible at reasonable cost.
