Frequently asked questions

What is the exact lug width of the Omega De Ville 424.18.27.60.55.001?

The lug width of the De Ville 424.18.27.60.55.001 is 20mm. This is the distance between the two terminal points of the case where the spring bars are inserted. This dimension is specific to this model and is essential for purchasing compatible straps.

Which type of strap is best suited for the Omega De Ville 424.18.27.60.55.001?

Alligator represents the classic choice par excellence: its natural granular texture enhances the sobriety of the steel case. Alternatively, shell cordovan offers intense luminosity, while vegetable-tanned calf provides an organic patina that ages nobly. For less formal contexts, satin rubber straps ensure aesthetic versatility.

How do you change the strap on the Omega De Ville 424.18.27.60.55.001?

The strap is replaced by removing the spring bars from the case lugs using a dedicated tool (spring bar removal tool). After extracting the bar from the old strap, insert it into the new strap ensuring the terminals are correctly positioned. It is advisable to have this operation performed by an expert watchmaker to avoid scratches.

Can I use an aftermarket 20mm strap on an Omega De Ville 424.18.27.60.55.001?

Yes, all straps with a 20mm lug width are compatible with the De Ville 424.18.27.60.55.001. You can choose from various customizable online options or opt for bespoke straps made by specialized artisans such as Casati Milano atelier.

How long does a leather strap last on the Omega De Ville 424.18.27.60.55.001?

The durability depends on the material and usage. An artisanal quality alligator strap typically lasts 5-7 years with regular maintenance. Shell cordovan can last 8-10 years thanks to its superior molecular density. Vegetable-tanned calf evolves over time developing patina, but maintains structural functionality for 4-6 years. The Casati Milano warranty covers 18 months of use.
