About the Seamaster Aqua Terra family

The Aqua Terra joined the Seamaster family in the early 2000s as a versatile everyday watch with 150 metres of water resistance and a dressier look than Omega's dive models. Its teak-pattern dial, inspired by the decks of sailing yachts, is the line's signature, and since the 2017 update the stripes run horizontally.

The catalog holds a very wide range: men's sizes such as 38 and 41 mm, smaller ladies' sizes, GMT and Worldtimer versions, and cases in steel, titanium and several gold alloys. Modern models use Master Chronometer calibers such as the 8900. Dealers identify a piece by its full reference, which gives size, metal, movement and dial colour, since many variants look alike.
