OMEGA’s line of water resistant watches dates all the way back to 1932. The Seamaster name was introduced in 1947. Up through the 1960’s, the Seamaster models paralleled the traditional style of dress watches, such as the OMEGA DeVille (some were even labeled as a ‘Seamaster DeVille’). While these watches were water resistant (back then, they could still use the term ‘water-proof’), few had functions other than basic display of the time and occasionally the date.In the 1970’s, OMEGA took the Seamaster line in a much sportier and often trendier direction. During this decade, Seamasters took on a heavy sport and functional look and came with more diver-oriented features, such as higher depth ratings, calibrated rotating bezels, chronograph functions, and high-visibility dials.OMEGA’s current Seamaster line consists of the Seamaster Aqua Terra with 150 meter water resistance and the Seamaster Professional series (introduced in 1993) with 300 meter water resistance and diving-oriented features in a sports watch style. Other recent and generally still available models include the Seamaster 120 series with 120 meter water-resistance in a dress watch style.OMEGA currently makes several models of Seamaster watches, with numerous sub variations of color, bracelet, movement, and casing sizes. The main Seamaster models in production are:
- Seamaster Professional Diver (automatic and quartz movements; also sometimes known as the 300M; available in a full size mens, mid size mens, and ladies models). The mens models come in two different dial/hands styles: the classic “skeleton hand” introduced in 1993 and the bolder “GMT style” introduced in 1998.
- Seamaster Professional Chronograph (automatic movement only, very large and heavy watch, available in titanium, mens size only)
- Seamaster Professional GMT (Introduced late 1998, automatic movement, mens size only, mens size only) variation of the 300M with an additional GMT hand and a different look to the face and bezel
