Strap for Seamaster Aqua Terra 150M Co-Axial 34 Stainless Steel / Black / Bracelet

The Omega Aqua Terra 231.10.34.20.01.001 has a lug width of 20mm. This is the distance between the two attachment points of the strap on the case. It is essential not to confuse this measurement with the 22mm found on other Omega models, as an incorrectly sized strap will not fit properly and may damage the case.

The ideal strap depends on the intended use. For pure elegance, dark brown alligator leather in vegetable tanning enhances the teak dial without rival. For everyday versatility, vegetable-tanned calf leather with natural patina offers superior aesthetic longevity. For aquatic or summer contexts, fine-grain rubber maintains authenticity without practical compromises.

Position the watch on a flat surface with the dial facing upward. Measure the distance from the inner face of one lug (the metal support for the strap) to the inner face of the other lug, in a straight line perpendicular to the bezel. The result must be exactly 20mm. Avoid measuring from the outer edge of the lugs, as this would result in an overestimate.

Yes, provided the strap is specifically designed for a 20mm lug width. Milano Straps' artisanal straps are manufactured with a tolerance of less than 0.5mm to ensure perfect seating of the spring bars in the original Omega seats, without play or forcing.

The lifespan of a leather strap depends on the quality of the tanning and usage. A premium alligator or calf leather strap, worn daily under normal conditions, lasts 3-5 years before showing significant signs of wear. Continuous exposure to water and perspiration accelerates the process. A quality rubber strap lasts 5-7 years. The warranty offered by Casati Milano covers 18 months from manufacturing defects.
