Omega Seamaster Aqua Terra 150M Worldtimer, reference 220.10.43.22.03.002, a 43mm steel world-timer built around a laser-engraved globe at the heart of the dial.
A polished and brushed stainless steel case frames a summer blue 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. Pre-owned in excellent condition, the case, bracelet, and crystal clean with only minimal signs of careful wear, complete with box and papers and set on its matching steel bracelet.
