Strap for Seamaster Aqua Terra 150M Master Chronometer 43 Worldtimer Stainless Steel / Blue / Bracelet

The Omega Aqua Terra 43mm (220.10.43.22.03.001) features a 21 millimeter lug width. This is the distance between the two metal pins on which the strap rests. It is a precise measurement and is not interchangeable with standard 20mm or 22mm widths.

For the 220.10.43.22.03.001, straps in alligator, vegetable-tanned calf leather, or rubber are recommended. Alligator offers maximum elegance with natural grain, vegetable-tanned calf develops a patina over time, while rubber guarantees maximum resistance in humid environments. The choice depends on the context of use and color preferences.

The strap is changed by removing the horizontal metal pins (spring bars). Using a spring bar remover, push the pin from one side, extract the strap from that opening, then insert the new strap by aligning the internal hole with the pin and allowing it to snap naturally into position. If you lack experience, consult a professional jeweler.

No. The Aqua Terra 220.10.43.22.03.001 requires specific 21mm width straps. Standard 20mm or 22mm straps will not fit correctly. The recommendation is to opt for custom or semi-custom straps that respect this uncommon dimension.

A leather strap with vegetable tanning, worn daily under normal conditions, typically lasts 3-5 years. Frequent exposure to water, sweat, and humidity reduces the lifespan to 2-3 years. Alligator or shell cordovan straps, with proper maintenance, can exceed 5 years. Rubber is virtually unlimited in durability.
