Strap for De Ville Prestige Co-Axial 36.8 Yellow Gold / Silver / Diamond / Bracelet

The lug width of the De Ville 424.55.37.20.52.002 is precisely 19 millimetres. This measurement is specific and not interchangeable: an 18 mm strap will create lateral play, while a 20 mm strap will not fit into the lugs without force. To verify, measure perpendicularly at the base of the inner lug with a calliper or digital ruler.

Natural brown alligator represents the historical pairing: the rectangular texture contrasts elegantly with the case's smoothness, and the warm tone reflects the yellow gold. Alternatively, vegetable-tanned calf leather develops an advanced patina over time, acquiring chromatic depth. For timeless elegance, dark blue calf leather with a deployant clasp maintains formal appearance and allows you to reverse the strap every three months.

Use a strap tool or precision spring bar removal tool. Position the watch on a soft cloth with the caseback facing up. Locate the small spring bars at the ends of the lugs, press gently inward to release the spring and remove the original strap. Insert the new strap by aligning it with the two lugs, allowing the spring to click into position. Proceed one side at a time to avoid damage. If inexperienced, contact an Omega service centre or specialised atelier.

Yes, provided the strap is profiled for exact 19 millimetre lugs. Verify that the lug width dimensions match your measurement. Custom bespoke straps can be commissioned in any material—alligator, calf, shell cordovan—as long as they are made to specifications for 19 mm lugs.

A high-quality alligator or vegetable-tanned calf strap lasts on average 18-24 months with daily wear. Natural patina develops in the first year, acquiring deeper texture and colour. Longevity depends on frequency of wear, water exposure and care: a strap reversed every three months and protected from humidity will extend its life to 3-4 years. The 18-month warranty covers manufacturing defects; replacement for natural wear is advisory.
