The refined elegance of Grand Seiko
STGK009 catches the eye with its mother-of-pearl dial and with a blue seconds hand that is tempered by hand to a deep and powerful blue. With lines that are classic but details that are distinctively Grand Seiko, it is at once subtle and yet striking. It is powered by a remarkable automatic movement created especially for Grand Seiko’s women's watches which combines durability, accuracy and a remarkable 50 hours of power reserve with a slimness that belies the movement’s strength. The elegance shines, both inside and out.
A new automatic series for women
Slimness and performance in perfect harmony.
The new Grand Seiko automatic calibre 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.
