Frequently asked questions
What is the exact lug width of the Omega De Ville 4851.61.31?
The Omega De Ville 4851.61.31 has a lug width of 20 millimeters. This measurement is certified and represents the construction standard for this model. You can verify it by consulting the original Omega documentation or by measuring the space between the lugs with a digital caliper.
What is the best material for a strap for the De Ville 4851.61.31?
Alligator is the most appropriate choice for this timepiece: its natural grain and lively texture reflect the restrained elegance of the De Ville dial. Dark gray or cognac alligator enhances the tones of the steel and communicates authority. For everyday versatility, vegetable-tanned calf offers a less pronounced appearance and develops a personal patina over time. Shell cordovan represents a premium option for those who appreciate noble materials with long-term evolution.
How do I change the strap on the Omega De Ville 4851.61.31?
The De Ville 4851.61.31 is equipped with standard 20 millimeter lugs. To remove the original strap, use a pin remover tool specifically designed for 20mm lugs, or entrust the operation to a professional watchmaker. Insert the new strap into the lugs ensuring that the pins are fully inserted and the tension is uniform. If the strap has a deployant clasp, verify that the mechanism closes securely.
Is an aftermarket strap compatible with the De Ville 4851.61.31?
Yes, any strap with a lug width of 20 millimeters is compatible with the 4851.61.31. Online you can find 20mm straps ready to ship in various leathers and colors. For a personalized experience, the Casati Milano atelier creates custom straps by specifying leather, color, stitching and initials, with an 18-month warranty.
How long does a leather strap last on this watch?
Durability depends on the material, usage and maintenance. A quality alligator or calf strap, worn daily, maintains functionality and appearance for 2-4 years before requiring replacement. Shell cordovan, thanks to its density, can last 5-7 years if properly cared for. Periodic maintenance (gentle cleaning, light conditioning) extends longevity. Avoid prolonged exposure to water and direct UV rays.
