Strap for Seamaster Aqua Terra 150m Co-Axial 43 Annual Calendar Red Gold / Grey / Bracelet

The Omega Aqua Terra 231.50.43.22.06.001 has a lug width of 21mm. This dimension indicates the space between the lugs (lateral pins) of the case. To verify, use a caliper measuring from pin to pin on the inner side of the case, without confusing it with the actual strap width.

For the 231.50.43.22.06.001 we recommend alligator in chocolate brown or vegetable-tanned calf for color continuity with the red gold. In contrast, black alligator creates sophistication. Intense brown shell cordovan offers maximum durability and authentic nautical texture.

Remove the current strap using a spring bar tool to push the lugs (small pins that support the strap) laterally. Insert the new strap aligning the slots to the pins and return the pins to position. Verify that the strap is secure before wearing the watch.

Yes, any strap with a 21mm lug width is compatible with the Aqua Terra 43 red gold.
