Strap for Seamaster Aqua Terra 150M Co-Axial 43 GMT Chronograph Red Gold / Silver / Bracelet

The lug width of the Omega Aqua Terra 231.50.43.52.02.001 is 22 millimetres. This measurement is calculated from the base of the lug groove on one side to the other, perpendicular to the dial plane. A 22mm strap will fit precisely into the lug grooves of the case without excessive play or undesired tension, ensuring correct fitting and optimal visual readability.

For the 231.50.43.52.02.001, alligator remains the most coherent choice with rose gold Sedna, thanks to its natural texture that dialogues with the warm metallic tone of the case. Alternatively, vegetable-tanned calf offers softness and develops a patina over time, whilst shell cordovan provides natural lustre and fibre density ideal for evening wear. For versatility, a technical rubber strap maintains the Aqua Terra collection's sporting element.

Changing the strap requires a spring bar tool (a specific tool for removing lugs). Position the watch with the dial facing downward on a soft surface, insert the spring bar tool into the small slot on the inside edge of the lug, apply gentle pressure toward the case centre to compress the spring, and slide the strap outward. Repeat on the other lug. To refit, align the new strap's holes with the lugs and press until the spring clicks into place.

Yes, the strap is fully interchangeable with any compatible 22mm strap, regardless of watch brand. However, to maximise aesthetic coherence with rose gold Sedna and the design of the 231.50.43.52.02.001, it is advisable to select premium materials and colours that reflect the formal-sporting identity of the Aqua Terra collection, such as alligator, calf or shell cordovan in neutral or warm tones.

The lifespan of a leather strap depends on use, maintenance and material quality. A high-quality alligator or calf strap, worn regularly (4-5 days per week), typically lasts 3-5 years before requiring replacement. Vegetable-tanned leather and shell cordovan, being denser fibres, tend to have greater longevity. Prolonged exposure to moisture and perspiration reduces lifespan; storage in dry conditions and occasional treatment with protective products specifically designed for leather significantly extend strap life.
