Frequently asked questions

What is the lug width of the Omega De Ville 4370.31.00?

The lug width of the De Ville Prestige 4370.31.00 is 20 millimetres. This width represents the space between the inner edge of the left lug and the inner edge of the right lug, and is the fundamental parameter for selecting a compatible strap. Always ensure you measure this dimension accurately to avoid incompatibility.

What strap material is recommended for the De Ville 4370.31.00?

Alligator represents the choice of excellence for this dressy model, thanks to its regular and refined texture that enhances the two-tone case. For greater versatility, vegetable-tanned calf offers pronounced character and visible aging. Shell cordovan is ideal for those seeking maximum durability over time.

How do I change the strap on my Omega De Ville 4370.31.00?

To change the strap, use a specific spring bar tool to gently remove the pins that hold the strap in position. Insert the new 20mm strap from the ends, ensuring the pins click correctly into place. If you are not experienced, a specialist watchmaker will perform the operation in just a few minutes.

Can I use an aftermarket strap on an Omega De Ville Prestige 4370.31.00?

Yes, any strap with a 20mm lug width is compatible with the De Ville 4370.31.00. Milano Straps offers a selection of artisanal aftermarket straps, customisable in colour, thickness and material, that maintain the formal elegance of the original Omega model.

How long does a leather strap last on a watch like the De Ville 4370.31.00?

The durability depends on the material and usage. A quality alligator or calf strap, with regular care, can last 3-5 years of daily use. Shell cordovan, thanks to its superior density, can last over 7 years. Milano Straps provides an 18-month warranty on leather straps made at the Casati Milano atelier.
