Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Stainless Steel / Sedna Gold / Diamond / MOP / Bracelet

The Omega Aqua Terra 38mm (220.25.38.20.55.001) has a lug width of 19mm. This dimension is integrated into the case construction and ensures balanced proportions. To verify: measure the distance between the inner edges of the lugs at the widest point below the case.

To enhance the two-tone design, we recommend a smoked brown or bourbon alligator that reflects the warmth of Sedna Gold, or vegetable-tanned calf leather for a natural texture that develops patina over time. For versatility, black FKM™ rubber maintains formal elegance with daily practicality.

The Aqua Terra has integrated lugs, so strap changes require specialized tools to open the spring bars. We recommend contacting an authorized Omega service center or certified professionals. Atelier Casati Milano offers strap replacement services with warranty.

No, it is not recommended. The specific lug width of this model is 19mm. A 20mm strap creates lateral stress and gradually deforms the lug profile. Always use the correct 19mm width.

A high-quality artisanal alligator or calf strap typically lasts 3–5 years with daily wear and routine maintenance (periodic cleaning, quick drying after water contact). Durability depends on exposure to perspiration, humidity, and UV rays. FKM™ rubber straps have longer lifespans, 5–7 years.
