高振頻精準度與三日動力儲存，首款Grand Seiko機械計時碼錶：Tentagraph
就像每一款Grand Seiko作品，對精準度的追求是全新Tentagraph腕錶的核心理念，其計時碼錶機芯的基礎是革命性Hi-Beat Caliber 9SA5機芯。如同Caliber 9SA5機芯，全新Tentagraph Caliber 9SC5機芯每秒振動10次，確保碼錶計時以及當下時間的高精準性。而且，拜其節能擒縱裝置與兩個發條盒所賜，Tentagraph在啟用碼錶功能後，依然能運行三日之久，因此成為業界現今動力儲存最長久的每秒振動10次計時碼錶*。此外，Tentagraph經過為期更久的新測試程序。如同所有Grand Seiko機械機芯，Tentagraph的走時精準度經歷為期17天、六個位置與三種溫度的評測；此外，它還經歷在啟動碼錶功能後，於三個位置的精準度測試，且為期三天。因此，總計下來，每只Tentagraph共經過20天的測試以確保符合Grand Seiko的日差+5至-3秒標準。

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 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 hands. The recessed sub-dials sit a level below the main time-of-day display, enhancing the Tentagraph 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
The Tentagraph’s name describes key features of the Caliber 9SC5 movement inside: Ten beats per second, three days of power reserve, automatic winding, and chronograph.
Fully wound, the watch runs for 72 hours when the chronograph is in operation, which makes Tentagraph the 10-beat-per-second chronograph with the longest power reserve in the industry today*.
