History of Grand Seiko | Grand Seiko | SEIKO WATCH CORPORATION

		Grand Seiko was born. The first Grand Seiko model was produced in Suwa Seikosha in Nagano prefecture in central Japan.
		A second-generation model was launched, with a calendar function and with water resistance increased to 50 meters.
		[ 44GS ] Daini Seikosha (now Seiko Instruments) produced its first Grand Seiko watch. It was the first model to embody the exterior design concept of 'Grand Seiko Style' which endures to this day. [ 62GS ] The first Grand Seiko self-winding model.
		[ 61GS ] The first Grand Seiko automatic winding 10 beat model. This 10 beat caliber provided superior isochronism, and a high level of precision that made it more resisitant to changes in position and external impact. The winding mechanism used SEIKO's original Magic Lever mechanism. 6IGS was the hi-beat caliber ever made in Japan. [ 45GS ] A manual 10-beat model, featuring a slimmer movement, Like the automatic 61GS, it delivered a higher level of precision that made it more stable in different usage situations. The date calendar featured an instant-change mechanism. [ 19GS ] The first Grand Seiko watch for women. It had a 10 beat, high precision movement. It may have been the first 10 beat women's watch in the world.
		V.F.A. stands for "Very Fine Adjusted." This super high precision model sought to explore the farthest limits of accuracy in a mechanical watch. It delivered a monthly rate of ± one minute or less.
		[ 56GS ] After accuracy, size reduction was the next challenge for Grand Seiko. This caliber was automatic winding and although just 4.5mm deep, it retained the high precision of its predecessors. Thinness was not just an engineer's challenge. "Easy to wear" was part of the "Best Basic" concept and this slimmer watch sat more easily on the wrist. [ 61GS ] The Grand Seiko Special aimed for a yet higher standard of precision, more exacting even than the GS standard of the time.
		Aiming for the highest possible precision in women's mechanical watches, this model delivered a monthly accuracy rate of ± two minutes.
		The first "Grand Seiko" quartz watch. It delivered accuracy of 10 seconds per year, 25 times higher than other regular quartz movements.
		A Grand Seiko quartz watch for women, also with 10 second-a-year accuracy.
		'Quartz that surpasses quartz.' Pushing back the boundaries again, this quartz model set new standards of precision by incorporating systems like the 'backlash auto-adjust mechanism,' which had never before been achieved in a conventional quartz watch, a twin-pulse quartz mechanism and an instant calendar change mechanism.
		The first new Grand Seiko mechanical caliber in twenty years. It set a new standard, with cutting-edge production technology making possible a new interpretation of the traditional values of Grand Seiko.
		For the first time in Grand Seiko history, this watch featured a fourth hand, showing GMT.
		The launch of a quartz anti-magnetic watch, with 40,000A/m, a level of anti-magnetic protection that far exceeded all watchmaking norms.
		The new and unique Spring Drive caliber is added to Grand Seiko. It delivers an accuracy rate of ±1 second a day.
		A second-generation Spring Drive caliber is added to Grand Seiko, delivering a long power reserve of 72 hours.
		The first Spring Drive Chronograph in Grand Seiko.
		An automatic winding 10 beat movement, developed for Grand Seiko, the first in 41 years. It features a new dynamic spring and balance spring made from new, SEIKO-created, alloys SPRON530 and 610 respectively.
		A new automatic caliber with a power reserve of 3 days. Additionally, this model used the newest materials for its balance spring and escapement, improving the stability of its precision during actual use.
