Omega Seamaster Aqua Terra 150M ref 220.10.43.22.03.001 pairs the refined aesthetic of the Aqua Terra collection with a Worldtimer dial configuration. Global destinations surround the dial, featuring red font for London (GMT), silver font for locations that are +1 hour in the summertime, and blue font for locations without daylight savings. Even more remarkable is the center of the dial, which features a depiction of the Earth in grade 5 Titanium that has been laser ablated to reveal the continents in relief. Surrounding the globe is a glass 24-hour ring in light and dark blue to distinguish between day and night hours. This Omega is powered by the caliber 8938 self-winding mechanical movement with a 60-hour power reserve.
