Frequently asked questions

What is the lug width of the Omega De Ville 4657.50.31?

The Omega De Ville 4657.50.31 is equipped with an 18mm lug width, a classic size that allows you to mount a wide range of artisan straps. To verify compatibility, measure the distance between the pins protruding from the case: it must be exactly 18mm.

Which strap materials pair best with a De Ville in yellow gold?

For yellow gold, we recommend alligator leather in natural or cognac tones (which echoes the warmth of gold), Italian vegetable-tanned calf for a formal look, and burgundy shell cordovan for more structured occasions. Avoid straps with overly saturated colors: the tone of gold requires sober accompaniment.

How do I change the strap on my Omega De Ville 4657.50.31?

Equip yourself with a watchmaker's toolkit containing specific tools for lugs. Remove the lateral pins (spring bars) by pushing inward with a flat tool and lifting the strap. Insert the pins of the new strap into the case housings, ensuring they are aligned and properly seated. This operation requires millimetric precision: if you are not experienced, consult a professional watchmaker.

Can I mount an aftermarket strap on an Omega De Ville 4657.50.31?

Yes, any strap with an 18mm lug width is compatible. However, to preserve the value of the yellow gold case, we recommend artisan-quality straps in noble materials: premium leather (alligator, shell cordovan, vegetable-tanned calf) maintains aesthetic balance and watch value over time. Generic straps in synthetic leather or cheap rubber diminish your investment.

How long does a leather strap last on an Omega De Ville 4657.50.31?

Durability depends on the material and intensity of use. An artisan-quality alligator or shell cordovan strap, with appropriate maintenance (monthly cleaning, drying after moisture exposure), guarantees 4-6 years of daily wear. Vegetable-tanned calf, more delicate, has an average lifespan of 2-3 years. Alternating use with other straps significantly extends durability. A Casati Milano strap includes an 18-month warranty and regeneration option with buckle replacement.
