Strap for De Ville Prestige Co-Axial 36.5 Stainless Steel / Yellow Gold / Silver / Bracelet

The lug width of the De Ville 4374.31.00 is 20mm. This measurement is crucial when purchasing compatible straps: measure with a ruler between the two lugs without compressing the case. Do not confuse lug width with case diameter (36.50mm): these are separate and independent dimensions.

The best strap depends on your case and intended use. For a two-tone yellow gold and steel model, dark brown or black alligator with a steel keeper ensures maximum versatility and aesthetic harmony. Vegetable-tanned calf leather represents the classic European alternative, particularly appreciated for the natural patina it develops over time.

Strap replacement is performed using a spring bar tool: position the tool under the fixing pin, compress slightly to release the internal spring, and extract the old strap. Insert the new one by aligning the holes with the lugs and compress until you hear a click. This is a delicate operation on valuable watches: entrust it to professionals if you lack experience.

Yes, any strap with a 20mm lug width is mechanically compatible. Aesthetic compatibility, however, depends on proportions, thickness, and material: a lower-quality strap or one that is excessively stiff may alter the visual balance of the case. Milano Straps offers 20mm straps specifically selected for Omega dress models.

The lifespan of a leather strap depends on frequency of use, climate, and material. High-quality alligator or artisanal calf leather, with ordinary maintenance (avoiding prolonged water exposure and excess humidity), lasts 3-5 years of daily wear. Vegetable-tanned straps age more elegantly but require replacement sooner than industrial tannery leathers with synthetic treatments.
