Omega Seamaster Aqua Terra 150M 41 mm, titanium on rubber strap

Built for sporting comfort, the ergonomically designed "Ultra Light" is fashioned from an alloy called Gamma Titanium, a strong yet lightwatch_case_weight material used in the aeronautical industry. The use of Gamma Titanium is a first for OMEGA. As is the telescopic crown, which can be stowed inside the case when not in use.

Presented on a black rubber strap, the watch includes a sandblasted grade 5 titanium dial featuring the iconic Aqua Terra stripes. When worn on the additional sporty fabric strap, the watch weighs just 55 grams.

This 41 mm Aqua Terra makes bold use of green on the aluminium seconds hand, Seamaster logo, quarter hour markers and strap stitching. The watch is powered by the OMEGA Co-Axial Master Chronometer Calibre 8928 Ti, the brand's first movement built from titanium.
