Features
This mechanical chronograph was created in the Evolution 9 Style, a unique design method that combines the spirit of Grand Seiko and the aesthetic beauty of Japan to reach new heights. The dial captures Mount Iwate, topped with fresh snow, a merger of the harsh winter’s crisp blue sky and the subtle blue tint of the newly fallen snow. The deep snowfall is represented by the snow-blue dial color and an embossed pattern inspired by the mountain’s ridgelines.
This model features the Mechanical Hi-Beat Chronograph Caliber 9SC5 oscillating at a rate of 10 beats per second, which operates continuously for approximately 72 hours (about 3 days) when fully wound.

A two-layer dial expressing the contrast between rocky ridges and freshly fallen snow.
Nature’s beauty and the ever-changing seasons provide boundless inspiration for Grand Seiko. Mount Iwate, visible from the Grand Seiko Studio Shizukuishi, where the brand’s mechanical watches are crafted, presents breathtaking expressions throughout the year. The dial is inspired by Mount Iwate in the depth of winter, with the new snow depicted in snow-blue, while the mountain’s surface peeks through in the form of black sub-dials.
High legibility, a hallmark of the Evolution 9 Style
One signature of the Evolution 9 Style is its dial with redesigned indexes and hands. Created to achieve maximum legibility, their size and shape allow the wearer to read the time with just a glance. Everything about the Tentagraph’s chronograph and time-of-day displays has been thoroughly considered, from the placement of the hands relative to the indexes to the distance between the dial and the hands. By placing the date between four and five o’clock, an index can remain at each of the traditional hour positions while allowing for maximum readability for the time of day and the chronograph sub-dials.
