About the 61GS family
The 61GS, introduced in 1968, was Grand Seiko's first automatic high-beat watch, running at 36,000 vibrations per hour. Calibers 6145 and 6146 show the date or the day and date, and calibers 6155 and 6156 appear in later versions.
The 61GS is a key model for vintage Grand Seiko collectors. Check that the case lines are still sharp, that the dial and hands are original, and that the day and date change correctly.
