Frequently asked questions

What is the lug width of the Omega De Ville 4574.31.00?

The Omega De Ville 4574.31.00 has a lug width of 18mm. This measurement is specific to the model and must be verified with precision using a digital caliper, measuring perpendicularly the internal space of the integrated attachment from wall to wall.

What is the best material for a strap to pair with the De Ville 4574.31.00?

Vegetable-tanned alligator represents the optimal choice for this model, thanks to its regular grain that dialogues elegantly with the sculptural geometry of the case. Brushed calf offers a more informal alternative, while shell cordovan ensures an ideal aesthetic transition between formal and casual contexts.

How do you change the strap on the Omega De Ville 4574.31.00?

The Omega De Ville 4574.31.00 features a non-standard integrated attachment. For this reason, we recommend having the change performed by a watchmaker specialized in bespoke straps or at the Casati Milano atelier, where professionals understand the precise anatomy of this model.

Can I use an aftermarket 18mm strap on this De Ville?

Yes, provided that the strap is specifically constructed for the 18mm lug width and compatible with the integrated attachment of the model. We recommend verifying the technical specifications with the supplier before purchase to avoid structural incompatibilities.

How long does a leather strap last on an Omega De Ville 4574.31.00?

Durability depends on the material and usage. A vegetable-tanned alligator strap, if properly cared for, lasts 4-6 years in daily use, while shell cordovan, thanks to its crystalline density, can exceed 8 years. At Casati Milano all straps are guaranteed for 18 months and can be restored with periodic maintenance interventions.
