Frequently asked questions

What is the lug width of the Omega De Ville 4500.30.00?

The Omega De Ville 4500.30.00 has a lug width of 20mm. This dimension is proportionally calibrated to the case diameter of 34.70mm and ensures a perfect fit without lateral gaps, guaranteeing a harmonious visual integration between case and strap.

What is the best strap for the Omega De Ville 4500.30.00?

The choice depends on the context. For pure classic elegance: alligator with vegetable tanning or shell cordovan, which enhance the De Ville's sobriety. For sophisticated everyday wear: fine-grained calf with natural patina. For versatility: dense cotton NATO or rubber. Each option maintains the De Ville's identity while modifying its emotional character.

How do I change the strap on the Omega De Ville 4500.30.00?

The strap is removed by replacing the horizontal spring bars that pass through the case lugs. These bars are extracted with a spring bar tool, gently and perpendicularly to the case. Once removed, the old strap slides off and the new one is inserted by aligning the holes. A simple operation but one that requires care to avoid scratching the case.

Can I use an aftermarket strap on this Omega?

Yes, provided it is exactly 20mm wide. Milano Straps offers a wide range of compatible straps in leather, rubber and fabric, all handcrafted and customizable. The 18-month warranty from Casati Milano covers construction quality and durability even on valuable watches like the De Ville 4500.30.00.

How long does a leather strap last on a watch like this?

A quality leather strap, made with noble materials such as alligator or shell cordovan, lasts 3-5 years with responsible daily use. Durability depends on exposure to sweat, moisture and maintenance. A vegetable-tanned calf strap has slightly lower longevity (2-4 years) but develops characteristic patina. Milano Straps offers regeneration services and spring bar replacement to extend the life of the strap.
