The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. In this 41mm model, the symmetrical case has been crafted from stainless steel, with a wave-edged design featured on the back.
The silvery dial is distinguished by a horizontal “teak” pattern which is inspired by the wooden decks of luxury sailboats. There is also a date window at 6 o'clock and blackened hands and indexes filled with white Super-LumiNova. Orange is used for the central seconds hand, the "Seamaster" wording and the four quarter numbers on the minute track.
The grey strap is made from structured rubber and includes grey lining and an additional stainless steel link which integrates it to the case. This certified chronometer is powered by the OMEGA Master Chronometer calibre 8900, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
