A new automatic series for women

Slimness and performance in perfect harmony
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.
These high levels of performance are delivered by an 8 beat movement that is just 19.4mm in diameter and 4.49mm in height, which allows the case to fit every wrist and each timepiece to have an elegantly slim profile.

The Stainless steel versions with a diameter of 27.8mm, demonstrate Grand Seiko at its finest.
The cases are Zaratsu polished to give them the sparkle of quality that is the Grand Seiko signature, the seconds hand is made of steel that is blued” by hand and the other two hands have a central hairline stripe and are razor-edged to ensure that they catch even the slightest ray of light and are easy to see.

STGK009 has a mother of pearl dial with diamond-cut hour markers.

The beauty of the finishing is visible through the sapphire crystal case back.
