Strap for Seamaster Aqua Terra 150M Co-Axial 41.5 Red Gold / Grey

The Omega Aqua Terra 231.53.42.21.06.001 has a lug width of 20mm. This measurement refers to the internal distance between the two pins (spring bars) that attach the strap to the case. Always verify that the strap you purchase has exactly 20mm width to ensure complete compatibility and eliminate unwanted play.

To enhance the elegance of the Omega Aqua Terra 231.53.42.21.06.001 in rose gold, we recommend a cognac or black alligator leather strap, which creates a sophisticated chromatic dialogue. Alternatively, shell cordovan develops an extraordinary patina over time. For more sporty use, an FKM rubber strap keeps your wrist dry without aesthetic compromise.

The process is straightforward: place the watch on a soft cloth, locate the pins at the ends of the strap, use a dedicated tool (spring bar tool) to push the small metal hook inward and slide the pin out of its seat. Repeat on the other side. Insert the new strap in reverse, ensuring the pin is fully seated. If you are not experienced, consult a professional watchmaker.

All straps with 20mm lug width are compatible. Consult the online collection at milanostraps.it to find alligator, calf, shell cordovan, and rubber straps, customizable in color, length, and thread. The Casati Milano atelier also creates bespoke straps tailored to your specifications with an 18-month warranty.

A quality strap, exposed to normal use without frequent water contact, lasts on average 3-5 years before showing visible signs of wear. Moisture accelerates deterioration; salt water (sea) or chlorine contact reduces lifespan. Gentle cleaning every 2 weeks and application of protective balm every 6-8 weeks significantly extend the strap's useful life.
