Strap for Seamaster Aqua Terra 150M Co-Axial 42.2 Stainless Steel / Silver / Bracelet

The lug width is 20mm, measured between the inner attachments of the case. It is the standard for the entire contemporary Aqua Terra collection and guarantees compatibility with any artisanal strap of this width.

It depends on usage. Alligator is the classic formal choice, vegetable-tanned calf offers evolving patina over time, Hungarian shell cordovan guarantees structural uniqueness. For summer and water sports, a grey NATO or ventilated canvas maintains lightness without sacrificing authority.

Position the watch on a soft pad. Locate the small hole beneath each case lug (between the shoulder and crown, toward the crystal). With a spring bar tool (ball-end tool), push the internal stop to open the spring mechanism, then remove the old strap and fit the new one. The procedure takes 2-3 minutes.

Yes, provided it is 20mm lug width. High-quality artisanal straps from Milan, Genoa or France fit into Omega attachments with precise fitting, without adapters. They guarantee greater personalization compared to official straps.

An alligator or vegetable-tanned calf strap lasts 4-7 years with daily use and minimal maintenance (quarterly cleaning, annual conditioning). In very humid environments or tropical climates, durability reduces to 3-4 years. Hungarian shell cordovan tends to last longer (7-10 years) thanks to its more resistant vertical fiber structure.
