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.
Mechanical for women -18K gold model-
STGK004's case is 18K yellow gold. 42 diamonds are set into each bezel and 12 into each mother-of-pearl dial. One more and larger diamond is set into the crown.
This elegance is exquisitely complemented by the finest crocodile leather strap.
A diamond inspired pattern is sculpted into the mother-of-pearl.
High definition dual-curved sapphire crystal is equipped with anti-reflective coating.
The beauty of the finishing is visible through the sapphire crystal case back.
