The Omega De Ville 4875.50.01 is a dress watch with a 36.5 mm stainless steel case and integrated steel bracelet, introduced in the 1990s as a contemporary reinterpretation of elegant wristwear. It features the automatic Omega calibre 2500 with Co-Axial escapement, COSC-certified chronometer movement that reduces friction and extends service intervals. The watch has a 20 mm lug width, a date window, anti-reflective sapphire crystal on both sides, and 30 metres water resistance, designed for formal daily wear without rotating bezel or depth indicators.

Frequently asked questions

What is the exact lug width of the Omega De Ville 4875.50.01?

The lug width of the Omega De Ville 4875.50.01 is 20 millimetres. This measurement represents the distance between the case shoulders where the strap is attached. Always verify this measurement by positioning a ruler perpendicular directly between the case lugs, avoiding confusion between lug width and strap thickness.

What is the best strap material for the Omega De Ville 4875.50.01?

The best material depends on intended use and personal preferences. For formal elegance, vegetable-tanned alligator represents excellence, offering regular texture and natural grip. For versatility, vegetable-tanned calf develops a fascinating patina over time. For those who prioritize durability with refinement, shell cordovan maintains an unmatched glossy finish. For contemporary contexts, rubber preserves minimalist elegance without functional compromises.

How do you change straps on an Omega De Ville with integrated lugs?

The Omega De Ville 4875.50.01 features integrated steel lugs, meaning the strap attaches directly to this metal structure through drilled holes. To replace the strap, insert a spring bar (pin) through the hole in the lug, gently pushing the old strap out of the attachment holes. Then insert the new strap and ensure the spring bar is completely inserted on both sides.

Which aftermarket straps are compatible with the De Ville 4875.50.01?

Any strap with a 20 millimetre lug width is compatible with the De Ville 4875.50.01. Online you can find 20mm straps ready to ship, customizable in length, initials and thread colour. For optimal results, choose materials that highlight the watch's aesthetic sobriety, such as alligator, vegetable-tanned calf or shell cordovan, rather than overly sporty variants.

How long does a leather strap last on a watch like the De Ville 4875.50.01?

The lifespan of a leather strap depends on the material, frequency of use and care. An alligator or vegetable-tanned calf strap, used daily, generally maintains excellent functionality for 3-5 years. Shell cordovan, being denser and more robust, can last 5-7 years. To extend longevity, it is advisable to avoid prolonged exposure to moisture and direct heat. Casati Milano offers an 18-month warranty on made-to-order straps.
