Quartz watch 50th Anniversary Limited Edition
Fifty years ago, the world first quartz watch, the Seiko Quartz Astron, was launched. Perhaps no watch before or since has had a more important or lasting impact on the watch industry, as it marked the start of the quartz revolution which brought high precision timekeeping within the reach of all. To commemorate the Quartz Astron 50th anniversary, we are proud to announce a limited edition Grand Seiko watch which has a unique design and Grand Seiko latest quartz movement, the GMT caliber 9F86. This limited edition watch takes center stage within the Heritage Collection.
The case is classically Grand Seiko, polished to a beautiful distortion-free mirror finish. The dial is in Grand Seiko signature deep blue color and carries a pattern based on the quartz crystal symbol that was used for many years on Seiko quartz watches and acts as a quiet reminder of the Quartz Astron importance to modern horology.
The seconds and GMT hands are in gold, as are the 24 hour numerals inside the minute track and the name Grand Seiko.
The case back carries the Grand Seiko lion, the symbol of Grand Seiko. Alongside are the quartz crystal symbol and the words uartz Watch 50th Anniversary Each watch in this limited edition of 2019 has its own serial number which is also displayed on the case back.
The alignment of the case back might be different from that shown in the photograph.
