The Evolution 9 Style
In 2020, Grand Seiko introduced a new design philosophy called the Evolution 9 Style. It was based, of course, on the Grand Seiko Style which has always defined the design of all Grand Seiko watches and continues to do so. The Evolution 9 Style preserves the fundamentals of the Grand Seiko Style but adapts them for a new generation by setting new standards of legibility, comfort and beauty.
Ever since its creation in 1960, Grand Seiko has evolved continuously as new technologies, materials and ideas have opened up new design possibilities and the Evolution 9 Style is another step forward on this never-ending road. It was developed to further refine the aesthetics that have been at the heart of Grand Seiko from the start and to renew them for the years to come.
Contrast, depth and Lumibrite
The legibility could not be greater, thanks to the high contrast between the dial and hands, the precision of the engineering and the generous coatings of Lumibrite that the hands and the markers carry. Furthermore, each hand has its own distinctive shape, as does the 12 o’clock marker, so that the exact time can be read at a glance, even under water.
Spring Drive 5 Days Caliber 9RA5
Spring Drive is a unique watch technology. It generates energy like every other traditional mechanical watch but combines this with an electronic regulator to deliver a level of precision that no mechanical watch can match. The development of Spring Drive was possible because Grand Seiko is one of the very few manufacturers with mastery of both electronic and mechanical watchmaking.
In addition to achieving a high accuracy of ±10 seconds/month, this movement is 0.8mm thinner than the previous Caliber 9R65 by adopting the “Offset Magic Lever.” The movement is equipped with a power reserve indicator located on the dial side for safety during diving.
