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

The lug width of the Omega Aqua Terra 231.53.43.52.02.001 is 20mm. This measurement is obtained by positioning a digital caliper between the two lugs of the case on the inner side. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility and wrist stability.

For a 43mm Aqua Terra in rose gold, we recommend an alligator in dark shades (black, chocolate brown) or cognac, or a shell cordovan strap. These noble materials complement the precious case while maintaining the sports vocation. A more casual alternative is vegetable-tanned calf or an FKM rubber strap for water activities.

Changing the strap requires a specific tool (spring bar remover) to remove the lug pins. Position the watch on a soft surface, insert the pin into the lever hole, push gently to disengage, then extract the lug. Repeat for the other lug. The reverse operation installs the new strap. If inexperienced, contact an Omega service center or a professional watchmaker.

Yes, 20mm straps made by Milano Straps are specifically compatible with the Omega Aqua Terra 231.53.43.52.02.001. They are customizable in sizes, initials and choice of stitching thread. Each strap is crafted with meticulous attention to proportions and tolerances, guaranteeing perfect fit.

The lifespan of a leather strap depends on use, storage and material. A quality alligator or shell cordovan, with proper maintenance (avoiding extreme humidity, protecting from heat sources), lasts an average of 3-5 years with daily use. Milano Straps offers an 18-month warranty on straps made by Casati Milano, with the possibility of revision and restoration even afterwards.
