Just Serviced by Seiko. Comes with AquaStar Thermometer. Runs perfect. One Owner since new.Seiko introduced the reference 6217-8001 in 1965 and the “62MAS” was the first professional diver from the company. Seiko came out with a re-edition in 1970, but this one is the real deal.  

The “62MAS” is the OG Seiko professional diver's watch, and a lot of characteristics from this model have been used in other Seiko divers to this day. The nickname “62MAS” comes from the first two digits of the reference number – 62 – and MAS comes from "auto[MA]tic [S]elfdater," AKA automatic movement with date. Seiko saw a need for a professional dive watch in the 1960s and in 1965 they debuted this model. It is interesting to note that this model has the crown at three o’clock, while most other Seiko divers have it positioned at four o’clock. Seiko used a large crown for this model to make setting and changing the time easier, and the crown says “SEIKO,” which is a neat little detail.
