Strap for Seamaster Aqua Terra 150m Master Co-Axial 41.5 Stainless Steel / Red Golf / Grey

The lug width of the Omega Aqua Terra 231.23.42.21.06.003 is 20 millimeters. This is the horizontal distance between the two internal holes where the strap spring bars are inserted. It is essential to verify this measurement before purchasing an aftermarket strap to ensure mechanical and aesthetic compatibility.

For the 231.23.42.21.06.003, the best strap depends on use and personal taste. Smoked alligator or cognac alligator enhances the Sedna™ rose gold and offers formal elegance; vegetable-tanned calf leather ensures daily versatility; shell cordovan offers distinctive aging and superior resistance. The ideal choice is one that complements the watch's primary use context.

The strap is replaced using a removable spring bar tool, easily found online. Position the watch face-up, locate the spring bar on the case lug, insert the flat end of the tool under the spring bar to compress it, then remove the worn strap. Insert the new strap by aligning the holes with the spring bars and allow the retention mechanism to snap into place. If you prefer to avoid any risk, entrust the task to a professional watchmaker.

Yes, any strap with a 20mm lug width is compatible with the 231.23.42.21.06.003.

A quality leather strap, subjected to vegetable tanning, lasts an average of 3-5 years with moderate daily use. Durability depends on exposure to moisture, sweat and frequency of wear. Shell cordovan and alligator straps offer greater longevity. Periodic maintenance – gentle cleaning and leather conditioning – significantly extends the strap's lifespan. Casati Milano guarantees 18 months on all handcrafted straps produced.
