Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Yellow Gold / Green Sunburst / Bracelet

The lug width of the De Ville 424.20.40.20.10.001 is 20 millimetres. This measurement corresponds exactly to the space between the case lugs where the strap attaches via suspension pins. Always verify this measurement before purchasing an aftermarket strap to ensure proper compatibility.

Alligator is the highest formal choice for this model: the natural grain of the leather creates a sophisticated effect and its exceptional memory maintains structure over time. Vegetable-tanned calf offers versatility and develops an organic patina that harmonizes with the natural ageing of yellow gold. For daily or summer wear, synthetic FKM Viton rubber ensures stability in humid environments.

Position a digital calliper perpendicular to the suspension pins on the case, measuring the net distance between the inner edges of the holes. For the De Ville 424.20.40.20.10.001, Omega's factory tolerance is ±0.1 millimetres. A strap too narrow creates tension on the case; one too wide generates lateral movement and accelerated wear on the pins.

Yes, it is possible to change the strap yourself if you own a spring bar tool. However, for a timepiece of this quality and value, it is advisable to entrust it to an expert to avoid damage to the case or pins. Atelier Casati Milano also offers fitting services for custom straps.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts between 3 and 5 years with daily wear. Wear depends on factors such as frequency of use, perspiration, sun exposure and humidity. Vegetable tanning develops a natural patina, extending aesthetic life. Casati Milano artisanal straps include an 18-month warranty and can be regenerated through professional restoration.
