Strap for De Ville Quartz 27.5 Stainless Steel - Diamond / MOP / Bracelet

The lug width of the 434.15.28.60.55.001 model is 13mm. This width is specific to Omega's compact feminine collections and is decisive for strap selection: an incompatible lug width would result in improper seating on the spring bars and compromised aesthetics.

Alligator remains the choice of excellence: its fine grain and controlled lustre maintain the minimalist elegance of the case. Calf leather offers a versatile alternative with a richer natural patina. For dynamic daily use, natural rubber. Avoid materials with pronounced patterns or textures that would compete with the compact proportions of the piece.

The change occurs through the release of the two lateral spring bars, an operation that can be performed with a dedicated tool (spring bar tool) in which a thin lever is inserted between the case and the spring bar. Contact a qualified watchmaker if you lack experience to avoid damage to the case, or in Milan you can contact the Casati atelier for installation.

No. The 13mm lug width is specific and not compatible with standard formats (16mm, 18mm, 20mm). The spring bars will not seat correctly, compromising both security and aesthetics. Always search for 13mm straps or rely on craftsmen who work bespoke for this lug width.

A quality leather strap (alligator, vegetable-tanned calf) lasts approximately 3-5 years with moderate daily use, up to 8-10 years with careful maintenance. Durability depends on use, sun exposure, humidity, and care: avoid water, clean with a dry cloth, store away from direct light significantly extends service life.
