Strap for De Ville Master Chronometer 34 Sedna Gold / MOP - Diamond

The De Ville Prestige 434.53.34.20.55.001 has a lug width of 16mm. This measurement corresponds to the distance between the two spring bars that connect the case to the strap. All aftermarket straps with 16mm lug width are compatible with this model.

For the De Ville in Sedna Gold we recommend cognac or satin black alligator, paired with a painted steel deployante clasp. For daytime wear, vegetable-tanned calf leather in dove gray or cream white represents a contemporary alternative. Shell cordovan is ideal for those who appreciate dramatic aging and the natural patina that develops over time.

Strap replacement requires a spring bar remover tool to disengage the pins that connect the strap to the case. Position the tool under the pin, apply gentle downward pressure to release the spring, and slide the pin outward. Repeat on both sides. The operation requires care to avoid scratching the case lugs.

Certified quality aftermarket straps (such as those from the Casati Milano atelier) offer the same level of technical compatibility as original Omega models, maintaining the 16mm lug width and standard pins. The difference lies in the choice of artisanal materials and the possibility of customization in sizes, colors and finishes, equal to or superior in construction quality.

A high-quality artisanal leather strap (alligator, vegetable-tanned calf, shell cordovan) has an average lifespan of 3-5 years of daily use, varying depending on climate, humidity and frequency of use. Vegetable tanning and alligator tend to last longer than standard calf leather. Casati Milano atelier provides an 18-month warranty on every custom-made artisanal strap.
