Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Stainless Steel / Green / Rubber

The Omega Aqua Terra 220.12.38.20.10.001 has a lug width of 19mm. This is the exact distance between the inner shoulders of the two lugs on the case, measured perpendicularly. All compatible straps must have exactly 19mm width at the attachment points.

For the Aqua Terra 220.12.38.20.10.001 we recommend black or dark brown alligator for timeless elegance, shell cordovan for durability and longevity, or vegetable-tanned calf for a patina that ages with character. The choice depends on use: formal (black alligator), daily wear (calf), sports (rubber or NATO).

To change the strap, position the watch with the dial facing down. Use a thin tool (spring bar tool) to gently push the spring bar detent lever from the opposite side of the lug you wish to remove. The bar slides out easily. Repeat for the other side, then insert the new strap by following the reverse procedure.

All straps with 19mm lug width are compatible. You will find online straps in alligator, calf, shell cordovan, suede, rubber and NATO of the same width. On milanostraps.it you can choose from dozens of customizable models in color, stitching and initials.

A quality leather strap on an Aqua Terra 220.12.38.20.10.001 typically lasts 2-4 years under normal daily wear conditions. Alligator and shell cordovan resist longer (4-6 years), while calf requires more careful maintenance. Durability depends on exposure to moisture, sweat and climate conditions. With proper care (drying, conditioning), the useful life extends significantly.
