Strap for De Ville Co-Axial 38.7 GMT Stainless Steel / Grey

The Omega De Ville 4833.40.31 features a lug width of 18mm, standard for this 38.70mm case diameter. This measurement is consistent across most Prestige models of this generation and allows cross-compatibility with 18mm aftermarket straps.

A black or dark brown alligator strap with vegetable tanning represents the most elegant and versatile choice. Alligator reflects the formal character of the watch and ages magnificently. For alternatives, natural shell cordovan creates a sophisticated pairing on light dials, while vegetable-tanned calf leather offers a warm patina that develops over time.

Strap changing is a straightforward operation requiring a spring bar tool. Insert the flat blade into the spring bar notch, gently lift the opposite spring bar pin until it releases from the lug, then remove the old strap. Repeat in reverse order with the new strap, ensuring the pins are properly seated.

Yes, absolutely. The De Ville 4833.40.31 with 18mm lug width is fully compatible with any quality 18mm strap. The key is to verify the attachment width (18mm) and choose a material and style that respects the watch's formal identity: alligator, calf leather, or shell cordovan are the most recommended options.

A quality leather strap with vegetable tanning typically lasts 3-5 years with moderate daily use. Longevity depends on factors such as frequency of wear, sun exposure, contact with moisture and perspiration. Denser leathers like shell cordovan or alligator tend to last longer than calf, but still require periodic maintenance and protection from extreme weather conditions.
