Strap for De Ville Prestige Dewdrop Co-Axial 32.7 Red Gold / MOP Butterfly / Diamond / Bracelet

The Omega De Ville Prestige 424.55.33.20.55.006 has a lug width of exactly 20mm. This specific measurement reflects the harmonious proportions of the 32.70mm case and must be respected to the millimetre when choosing a strap to avoid micro-play in the structure.

Mississippi alligator in cognac brown or black remains the most natural choice, as its geometric grain amplifies the elegance of the guilloché dial. Excellent alternatives are vegetable-tanned calf for those seeking patina over time, or shell cordovan for those who accept no compromise on quality and durability.

The operation requires a specific tool called a spring bar tool. Insert the flat tip of the tool into the small holes visible under the lug, compressing the internal spring until the cylinder pops out. At that point the old strap slides off and the new one attaches to the case. If you are unsure, the Casati Milano atelier offers this service free of charge upon purchase of a bespoke strap.

A quality leather strap, worn daily, has a typical lifespan of 3–5 years before requiring replacement. If treated with care—protection from standing water, avoiding prolonged direct sun exposure, periodic cleaning—it can last up to 7 years. Shell cordovan, thanks to its fibrous structure, often exceeds 10 years of intensive use.
