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.
The 18k rose gold case is Zaratsu polished to give the timepiece the sparkle of quality that is the Grand Seiko signature. 42 diamonds are set into the bezel and 12 into each delicately engraved mother-of-pearl dial. One more and larger diamond is set into the crown.
