In 1964, Seiko introduced the second generation of Grand Seiko, labeled the “Self-Dater” model which was the first Grand Seiko to feature not only a date display, but also an enhanced water resistance of 50 meters. From the first Grand Seiko introduced in 1960, Grand Seiko was made to be the best practical watch. The Self-Dater, otherwise known as the 57GS, was the second perfect example of this bearing a Chronometer label on its dial.
