Strap for De Ville Prestige Automatic 34.7 Yellow Gold / Champagne

The lug width of the Omega De Ville 4600.11.02 is 20 mm. This measurement represents the internal distance between the two metal lugs that protrude from the sides of the case. Verifying this dimension is essential before purchasing an aftermarket strap: a smaller lug width will not fit, while a larger one creates gaps that compromise the visual integrity and stability of the watch during use.

For the De Ville 4600.11.02 in yellow gold, we recommend three primary options: black or brown alligator for maximum formal elegance; natural burgundy shell cordovan for a refined vintage style that develops patina over time; vegetable-tanned calf leather in neutral tones (grey, ivory) for everyday versatility. Avoid synthetic materials or economy rubber: yellow gold deserves noble leathers that will amplify the perceived value of the watch.

The strap is changed using a spring bar tool: place the watch face-down, insert the flat end of the tool into the small hole at the base of the lug, gently lift to pop the elastic pin from its seat, and repeat on the other side. Once the integrated bracelet is removed, the new 20mm strap fits in the same way by reversing the procedure. An operation that takes only a few minutes and requires no specialist knowledge.

A quality leather strap (alligator, shell cordovan or vegetable-tanned calf) lasts an average of 4-6 years with daily use, extendable to 8-10 years with proper maintenance: avoid prolonged water exposure, periodically condition with specific creams, and rotate the watch between multiple straps. Shell cordovan, thanks to its fibrous density, tends to last longer than alligator. Synthetic straps have lower durability (2-3 years) but require less maintenance.
