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.

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 latest Spron 610 alloy is used for the balance spring, the pallet fork and escapement wheel are made by MEMS engineering and each watch is put through a rigorous 17 day testing procedure.
