Grand Seiko Evolution 9 Collection Chronograph GMT
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 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.
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.
The Spring Drive Chronograph Caliber 9R86 delivers high accuracy measurement of both time of day and elapsed time. It has a precision of ±15 seconds a month, or ±1 second a day and, equally importantly, measures elapsed time not to the nearest fraction of a second but exactly, thanks to the fact that the glide motion hands stop at the very instant that the button is pressed. The chronograph measures time for up to 12 hours.
The 72 hour power reserve is maintained even if the chronograph is in operation.
