Grand Seiko Elegance 25 years of innovation and evolution | | For six years after Grand Seiko was created in 1960, each watch was tested, in-house, to the highest international “chronometer” standard. However , in 1966, a new, higher, regular was set and, from this day to this, every Great Seiko mechanical watch has been tested to ensure that it meets the “Grand Seiko Standard”.
In 1998, the bar was raised again. With the introduction of the first 9S calibers, new levels of performance had been reached and so a new and even higher “Grand Seiko Standard” was arranged. Today, before it is cased, each 9S mechanical movement is assessed over the course of 18 days within six different positions that reflect real-life usage and at three different temperatures, 8, 23 and 38 degrees Celsius.
In 2023 when the Caliber 9SC5 TENTAGRAPH was created, a further processing was made towards the standard, specifically for chronographs. It requires that every chronograph movement is tested for an additional three days with the chronograph inside continuous operation.

Since 1966, the “Grand Seiko Standard” has been a challenging target that every Grand Seiko mechanical view must reach. Times change but Awesome Seiko’s commitment to industry-leading standards never will.
Caliber 9SA5 is actually Grand Seiko’s most precise mechanical motion in more ways than one. Thanks to its 36, 000 vibrations each hour, its Dual Impulse Escapement and its Free-sprung Balance, it keeps time with a precision rate of +5 to -3 seconds a day, but its accuracy extends also to the way the date will be presented.
In most watches, the date takes several hours to change but Quality and reliability 9SA5 has a special mechanism that ensures that it changes within the blink of any eye. The primary focus of this system is a date indicator drive wheel that is just seven millimeters throughout diameter. Its springs as well as movable day finger, all made with MEMS technology, ensure that the time changes instantly. Even though it is usually hidden from view, this date-change device is beautifully finished by Grand Seiko’s craftsmen and women for whom precision and also craftsmanship are matters associated with equal pride whatever the component, visible or not. To watch the actual date change in a Competence 9SA5 enjoy is to appreciate the value of their skill. | |
