Seamaster Aqua Terra 150M GMT Worldtimer 75ème Anniversaire

This is the 75th-anniversary read on the same Aqua Terra GMT platform — same 43mm steel case, same 150m rating, but the dial shifts to a lighter Summer Blue and the function steps up to a full worldtimer rather than a simple second time zone. That's a meaningfully harder complication to fit in a 43mm case without the display turning illegible, and Omega manages it without stacking a second sub-dial. It's a watch for someone who crosses time zones often enough to want all of them at a glance, not just one — a busy dial, but a coherent one.
