Caliber 9S was an important movement for the Japanese watchmaker as it was designed with high precision and unprecedented durability in mind, two qualities that Grand Seiko is famous for. Since then, the 9S has equipped all Grand Seiko timepieces.

Over the years, the movement has also been enhanced with various innovations including new Spron alloy for the main and balance springs as well as the MEMS engineering that allows key components to be manufactured to tolerances as small as one thousandth of a millimetre.

For the anniversary collection, the first watch is Hi-Beat 36000 V.F.A. rendered in platinum. The acronym in the name refers to “Very Fine Adjusted”, which in turn indicates the movement’s high precision rate that exceeds even the Grand Seiko Standard.

The incredible precision of the 9S85 Hi-Beat 36000 caliber is +3 to -1 seconds per day, achieved via 34 days of adjustments and tests.
