Omega Seamaster Aqua Terra 150M Co-Axial GMT — Ref. 231.10.43.22.03.001

DISCONTINUED — 2017
This is the watch Omega never replaced. When the 220.xx Aqua Terra generation launched in 2017 with the Cal. 8900, every standard AT got a successor — except the GMT. Omega simply dropped the complication from the lineup and never looked back, which makes this 43mm reference the last Aqua Terra GMT ever produced. That orphan status gives it a strange position in the catalog: it's the only way to get a true GMT hand on an Aqua Terra case, and the Cal. 8605 — a 38-jewel derivative of the in-house 8500 with a dedicated 24-hour hand and independently adjustable local hour — is a movement that exists in no current-production Omega. The blue teak dial, exhibition caseback, and the slightly larger 43mm case (versus the standard 41.5mm AT of the same generation) give it a presence the time-only models don't carry, and the 21mm lug width sets it apart dimensionally from the 20mm standard.
