Evolution 9 Collection
Caractéristiques
A limited edition in celebration of the 15th anniversary of the Spring Drive Chronograph
This watch is powered by a specially adjusted movement, Caliber 9R96, which delivers an accuracy of ±10 seconds per month ( ±0.5 seconds per day). In addition to the time of day and date, it offers a GMT hand and a power reserve indicator. The chronograph measures elapsed time up to 12 hours and the seconds hand moves in perfect, continuous and silent glide motion as it does so. The deep blue of the dial and the bezel echo the color of the night sky and contrasts with the brightness of the high-intensity titanium case.

The Grand Seiko 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.

The bezel is made of sapphire to ensure that the watch is as impervious as possible to scratches. It rotates in both directions to allow a third time zone to be shown.


Spring Drive Chronograph GMT Caliber 9R96
Caliber 9R96 has a power reserve of 72 hours, which is maintained even if the chronograph is in use. The Grand Seiko lion in 18K gold graces the oscillating weight to symbolize the enhanced accuracy of ±10 seconds per month.
