Built with athletes, and golfers specifically, in mind, Omega's latest Seamaster has several unique features that help it weigh in at just 55g. The Aqua Terra Ultra Light is the company's first watch to have a case, back, and crown made from Gamma Titanium, an aeronautical alloy that's both harder and lighter than regular titanium. It's powered by the manually wound Calibre 8928, Omega's first-ever titanium movement, and the telescopic crown is also a company first, retreating into the case when not in use. The bezel is made from gray ceramic while the dial is sandblasted titanium with negative stripes. Splashes of color — red, blue, or green — can be seen on the seconds hand, logo, quarter-hour indexes, and the contrast stitching of the rubber strap; an additional fabric strap is also included.
