Strap for De Ville Co-Axial 35 Chronograph Stainless Steel Diamond / Grey / Strap

The lug width of the Omega De Ville 422.18.35.50.06.001 is exactly 20mm. This dimension is determined by the geometry of the 35mm case and the lug attachment bracket to the movement. It is essential to measure correctly with a digital caliper positioned perpendicular to the two attachment lugs to ensure a precise fit without lateral play.

For the Omega De Ville 422.18.35.50.06.001 we recommend three main materials: alligator (regular grain, perfect for formal minimalism), vegetable-tanned calf (chromatic evolution over time, daily versatility) and Horween shell cordovan (tactile density and natural lustre for those seeking sophistication). The choice depends on intended use and personal colour preference.

Changing the strap on this Omega requires the use of a spring bar tool. Locate the two lugs beneath the case where the lug attachments connect; insert the flat tip of the tool into one of the lateral holes, press downward to compress the spring and release the lug. Repeat on the other lug. Insert the new 20mm strap until it clicks into place. If you prefer to avoid any risk, you can request the fitting service at Casati Milano.

Yes, any certified 20mm strap is compatible with your Omega. Artisanal straps from Milano Straps are constructed to precise measurements (20mm ±0.2mm) and tested before shipping. What matters is that the lugs are the correct length (approximately 10-11mm per side) for a secure fit without play.

The lifespan of a leather strap depends on frequency of use, climate and maintenance. An alligator or vegetable-tanned calf strap lasts 3-5 years with moderate daily use (4-5 days per week). Shell cordovan, thanks to its density, easily reaches 5-7 years. Periodic maintenance with neutral cream and water protection extend the useful life of the strap.
