Strap for De Ville Hour Vision Master Chronometer Sedna Gold / Silver

The lug width is 20mm. It is measured by positioning a digital caliper between the two lugs on the case. This measurement is the exclusive parameter for verifying compatibility with aftermarket straps. Omega chose 20mm to balance the proportions of the 41mm case with standard European wrists.

Alligator in cognac brown or hazelnut shades represents the aristocratic choice, as the natural texture of crocodile leather enhances the charisma of Sedna Gold. Vegetable-tanned calf in bordeaux or black tones is ideal for formal occasions. Japanese shell cordovan offers a versatile solution with accelerated patina, while titanium-grey rubber allows refined summer pairings.

Use a spring bar removal tool. Position it under the lug on the case and push with gentle and constant pressure until the spring bar retracts enough to extract it. Repeat on the other side. Insert the new strap by aligning the lug holes, then reinsert the spring bars using the same tool. If you lack experience, rely on the professional service of Casati Milano.

Yes, provided it is certified for 20mm lug width. The straps from milanostraps.it are produced with premium leather and artisanal stitching, perfectly compatible. Many owners prefer the aftermarket strap to the bracelet for color versatility and summer comfort. Ensure that the strap has been tested on Omega timepieces to rule out attachment anomalies.

A premium leather strap, with vegetable tanning or alligator, lasts an average of 3-5 years with daily use and proper maintenance. The determining factor is exposure to moisture and sweat: those who wear the watch in summer or at the gym accelerate wear. Shell cordovan is more resistant. FKM rubber can last 5-7 years. Casati Milano offers an 18-month warranty and leather regeneration services.
