The Watch: The Aqua Terra was Omega's early 2000's bridge between dress and sports watches, their own Datejust competitor. The Omega Seamaster Aqua Terra 150M Master Co-Axial, reference 231.20.39.21.02.002, pairs a stainless steel case with an 18k yellow gold crown and bezel, and a two-tone bracelet.
The lacquered silver dial uses the Omega's Teak pattern, drawn from the planking on sailing yacht decks. Applied stick and dot indexes run the hours, with arrow hands above and a date window at 3 o’clock. Sapphire crystal front and back.
Inside is the Master Co-Axial calibre 8500, a certified chronometer built to resist magnetic fields above 15,000 gauss, delivering 60 hours of power reserve. Water resistance is 150 meters.
