The 62GS is the first automatic Grand Seiko and the family's best example of a recorded disagreement: the serial evidence has watches sold in 1966, while Grand Seiko itself dates the model to 1967, and the company's anniversary editions have kept the later date. This file records both and takes no side. The watch itself is unmistakable: no bezel at all, the crystal meeting the case directly, and the crown recessed at four o'clock because an automatic needs no daily winding, a design argument made in steel.
Inside is the 19,800 vph caliber 6245 with date or 6246 with day and date, in a run that ended by 1968 either way, making this one of the shortest windows in the family. First automatic, shortest run, most distinctive case: the 62GS is the family's quiet key, and its modern reissues have only pushed more collectors back toward the originals.
A two-year window and a bezel-free case that shows every touch of a polishing wheel. Condition is the whole market here, and the recessed crown is the detail counterfacts and swaps get wrong.
