Strap for Seamaster Aqua Terra 150M Co-Axial 43 GMT Stainless Steel / Red Gold / Grey

The lug width of the Omega Aqua Terra 231.23.43.22.06.001 is 22mm. This is the measurement between the two lugs (attachment points) where the strap is fitted to the case. Measure perpendicular to the case using a digital calliper. It is essential to verify the measurement personally, as manufacturing tolerances and wear can introduce variations of tenths of a millimetre over time.

Alligator leather with a coarse grain (natural hornback) creates the strongest visual harmony with the teak-textured dial. For predominantly formal wear, vegetable-tanned calf leather offers elegance without excess. Shell cordovan suits those seeking an exceptionally dense, compact leather. Sports rubber is a pragmatic choice for alternating office and outdoor use. The key is selecting a strap that respects the dual-tone red gold and stainless steel aesthetic of the case.

Remove the strap using a spring bar tool. Insert the tool's tip into the cavity beneath the lug and gently push upward until the elastic pin lifts. Repeat for the opposite lug. When fitting a new strap, ensure the passants (guide loops) adhere perfectly to the 22mm width: oversized passants create mechanical play, whilst undersized ones stress the leather during wear.

Yes, any artisanal 22mm strap is compatible with the 231.23.43.22.06.001. Customisable straps are available online in leather (alligator, calf, shell cordovan), technical materials (rubber, NATO), and finishes (stitching, monogramming). Standard warranty on leather straps is 12–18 months. Verify that passants are constructed with perfect adherence to the 22mm specification to avoid mechanical play.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) on a 43mm watch typically lasts 3–5 years with daily wear, provided it is not frequently exposed to water (the 231.23.43.22.06.001 is rated 15m water-resistant, meaning the strap is not designed for immersion). Alligator is the most durable; vegetable-tanned calf patinas beautifully over time. Shell cordovan, being exceptionally dense, can last 6–8 years. Rotating between multiple straps significantly extends the lifespan of each.
