The essence of Grand Seiko is infused with Japanese beauty.
Born in the pursuit of the ideal wristwatch, the Evolution 9 Collection evinces a new design grammar that is entirely consistent with the Grand Seiko Style of 1967. Through the new Evolution 9 Style, Grand Seiko forges a new path while honoring its origins.
Pursuing the ideal chronograph through a dial designed for legibility.
One signature of the Evolution 9 Style is its dial with redesigned indexes and hands, which have been created to achieve maximum legibility, allowing the wearer to check the time with just a glance. Everything about its 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 hands. The recessed sub-dials sit a level below the main time-of-day display, enhancing the dial’s depth and legibility. And by placing the date between four and five o’clock, Grand Seiko’s designers ensured an index remains at each of the traditional hour positions while allowing for maximum readability for the time of day and the chronograph sub-dials.
Features of the Tentagraph Caliber 9SC5
