Strap for De Ville Co-Axial 37.5 Platinum / Copper / LTD

The Omega De Ville 5921.61.31 features a lug width of 19 mm. This width is measured internally at the contact point between the strap and the lug, excluding any lateral decorations. It is important to verify compatibility with precision, as even minimal deviations can cause friction during insertion.

Alligator represents the most elegant choice for this model: the regular grain of this exotic leather amplifies the sobriety of the platinum case. Deep midnight blue, raven black, and aged cognac tones are recommended. Alternatively, Japanese shell cordovan in deep brown offers legendary durability and develops a golden patina over time that resonates magnificently with aged platinum.

The tapered lugs of the De Ville 5921.61.31 require attention: the strap must taper progressively toward the terminal end to adapt to the geometry. Use a spring bar tool, gently inserting the tip into the lateral slot of the lug and pressing lightly to release the spring. Proceed slowly to avoid scratches on the platinum. If you are not experienced, it is advisable to consult a professional.

Yes, provided they are manufactured for 19 mm lug width. It is essential to verify that the strap is specifically designed for tapered lugs: the progressive geometry from the case side toward the terminal end allows smooth insertion and secure retention. Artisanal straps, such as those from Casati Milano, are made to measure respecting this proportionality to ensure perfect compatibility.

Durability depends on the material and wear. Certified quality alligator offers 5-8 years of daily use before requiring replacement. Shell cordovan, thanks to its dense fibrous structure, can last 10-15 years. Vegetable-tanned leather offers 6-10 years. Durability increases if the strap is worn occasionally and stored in dry environments, away from moisture and direct sunlight. Light maintenance with specific creams significantly extends the useful life.
