Strap for Seamaster Aqua Terra 150M Co-Axial 30 Stainless Steel / Red Gold / Diamond / MOP / Bracelet

The lug width of this model is exactly 20mm. It is measured from the internal distance between the two pins where the strap attaches to the case. This dimension is standard for the 30mm Aqua Terra and is also reported in the official Omega reference (25 at the 4th position of the numbering).

For the 231.25.30.20.55.001, we recommend cognac alligator for chromatic harmony with the rose gold, or black shell cordovan for elegant contrast. Alfort calf in deep burgundy enhances the mother-of-pearl dial. FKM rubber remains ideal for sports contexts while maintaining luxury tone thanks to the steel deployant.

It is possible to change the strap by removing the original integrated bracelet using a special punch to detach the pins on the case lug. Milano Straps recommends entrusting the operation to an expert watchmaker to avoid damage. Our 20mm straps are pre-drilled to accommodate standard Omega pins, facilitating installation.

Theoretically yes, since the lug width is standard 20mm, but we recommend straps specifically built for luxury watches: attachment thicknesses, stitching quality and end finishing are different parameters compared to generic straps. Milano Straps offers 20mm straps tested on Aqua Terra with structural compatibility guarantee.

A quality alligator or shell cordovan strap, worn daily with care (avoiding prolonged exposure to water and humidity), lasts 4-6 years. Calf, being more delicate, lasts 2-3 years. Milano Straps offers an 18-month guarantee and provides reconditioning services through re-stitching and protective leather treatment on watches with desirable patina.
