Frequently asked questions

What is the lug width of the Omega De Ville 4500.50.00?

The Omega De Ville 4500.50.00 has a lug width of 18mm, the exact space between the pins that connect the bracelet to the lugs of the case. This width is essential for choosing compatible straps without fitting issues.

Which strap is best suited for the De Ville 4500.50.00?

For this dress watch model, straps in dark brown alligator, dove grey vegetable-tanned calf, or burgundy shell cordovan are ideal. Avoid thicknesses exceeding 1.6mm as they would alter the proportions of the thin case. A deployant clasp adds daily comfort while maintaining elegance.

How do you change the strap on the Omega De Ville 4500.50.00?

Remove the original bracelet using a spring bar tool or suitable implement, gently pressing the pins from the case lugs inward. Extract the pin completely, remove the bracelet, and repeat on the other side. Then insert the new strap by aligning the holes to the lugs and reinsert the pins until they click firmly in place.

Does the De Ville 4500.50.00 accept any 18mm aftermarket straps from any brand?

Yes, any strap with an 18mm lug width is compatible. However, we recommend choosing manufacturers that guarantee precise tolerances (±0.2mm). Custom-made straps from specialized ateliers ensure perfect fit and stitching finish consistent with Omega quality.

How long does a leather strap last on the De Ville 4500.50.00?

A high-quality alligator or calf strap, worn daily with periodic rotation (2-3 straps alternated), has an average lifespan of 3-5 years. Vegetable-tanned leather ages with visible patina but maintains structure. Wear accelerates in humid climates. Artisanal Casati Milano straps include an 18-month warranty and maintenance support.
