Omega Seamaster Aqua Terra 150M Worldtimer, reference 220.92.43.22.99.001, a 43mm titanium world-timer built around a laser-engraved globe at the heart of the dial.
Light and cool to the touch, a brushed and polished titanium case carries a grey dial whose center holds a titanium relief of the northern hemisphere, ringed by a twenty-four city world-time display and read against a GMT hand, with the date at six. An exhibition sapphire back reveals the movement, Omega's Co-Axial Master Chronometer automatic, certified against magnetic fields to 15,000 gauss and carrying a 60-hour reserve, rated to 150 meters. A 2025 example, pre-owned and very nearly as new, complete with box and papers and on its black rubber strap.
