Strap for De Ville Prestige Co-Axial 39.5 Power Reserve Yellow Gold / Silver

The lug width of the Omega De Ville 424.53.40.21.52.001 is 20mm. This measurement indicates the distance between the two upper lugs of the case and corresponds to the width your strap must have. Do not confuse this with the case diameter, which is 39.5mm. To verify, measure the space between the lugs with a ruler or digital caliper.

For this yellow gold timepiece, we recommend black alligator, cognac brown, or slate grey, or vegetable-tanned calf in warm tones. Burgundy shell cordovan represents the most refined solution. All straps must be 20mm wide and equipped with a flame or swallow-tail attachment compatible with the case lugs.

The strap is secured via swallow-tail attachments (horns) positioned on the case lugs. To change it: remove the old strap by sliding it out from the lugs, insert the new strap through the lower lug first, then thread the tail through the upper lug. Repeat on the other side. If unsure, consult a specialized watchmaker.

Yes. Any strap with a 20mm lug width is compatible with this reference, provided the swallow-tail attachment fits properly into the case lugs.

A quality leather strap, with vegetable tanning or genuine alligator, typically lasts 3-5 years with regular daily use, extendable to 7-10 years with periodic maintenance (gentle cleaning, protection from extreme humidity). Durability depends on exposure to water, sweat and climate variations. Casati Milano artisanal straps include 18-month warranty on craftsmanship and allow reconditioning services if needed.
