The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. This slim 30 mm model achieves its refined proportions through OMEGA's innovative Co-Axial Master Chronometer calibre 8751, certified at the industry's highest standard by the Swiss Federal Institute of Metrology (METAS).

Crafted in 18K Moonshine™ Gold, this model has a symmetrical polished case and features a polished bezel set with 46 diamonds and a screw-in caseback with wave-edged design.

The pearled white mother-of-pearl dial is in full glossy finish, with a circular date window at 6 o’clock. It is highlighted by 11 diamond hour markers and redesigned faceted hands, with the minute hand tapering to a delicate point. All the applied elements are in 18K Moonshine™ Gold, while the hands are crafted in 18K yellow gold with a PVD Moonshine™ Gold coating. The hands also feature white Super-LumiNova which emits a blue glow.

The watch is presented on an integrated 18K Moonshine™ Gold bracelet with beautifully rounded polished-brushed links, a foldover butterfly clasp, and OMEGA’s easy comfort-adjustment system.
