A new automatic series for women 

The new Grand Seiko automatic caliber 9S27 strikes that difficult and delicate balance between high performance and slimness that only a true “manufacture” can achieve. Its performance is outstanding, with a precision rate of +8 to -3 seconds a day and a power reserve of 50 hours. Each movement is made, assembled and adjusted by hand in the Shizukuishi Watch Studio in northern Japan and is made possible by the same high level of “manufacture” craftsmanship as goes into every other Grand Seiko mechanical watch.

Faqs

What is the “Grand Seiko Standard?”

The Grand Seiko Standard is a Seiko-exclusive accuracy standard for mechanical watches which has been established to ensure superior performance of Grand Seiko mechanical watches irrespective of the differences in environmental conditions in which a watch is used. The Grand Seiko Standard differs from the other recognised chronometer standards in two important respects. While most accuracy standard testing is done for five positions at two temperatures, the Grand Seiko Standard tests six positions at three temperatures. This is because the Grand Seiko Standard seeks to replicate real world conditions.

How accurate is Grand Seiko?

The accuracy of Grand Seiko differs according to the mechanism and caliber of your watch.
QUARTZ : The annual accuracy is ±10 seconds when worn on the wrist within a normal temperature range (between 5 ºC and 35 ºC) for approximately 8 hours per day.
SPRING DRIVE : Average monthly loss / gain is ±15 seconds when worn on the wrist within a normal temperature range (between 5 ºC and 35 ºC).
MECHANICAL : Accuracy of Grand Seiko mechanical watches when worn is specified within the target range of -1 to +10 seconds per day. To properly judge the accuracy under normal use conditions, check the mean value of gain / loss over a period of seven to ten days.
