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 8750, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).

This stainless steel model has a symmetrical polished case and features a screw-in caseback with wave-edged design.

The sandstone dial is sun-brushed and coloured with tinted lacquer, with a circular date window at 6 o’clock. It is highlighted by 11 boat hull-shaped indexes and redesigned faceted hands, with the minute hand tapering to a delicate point. All the applied elements and hands are in 18K white gold, while the indexes and hands are also filled with white Super-LumiNova which emits a blue glow.

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