TECHNICAL SPECIFICATIONS

MOVEMENT
The high-beat watch is powered by the revolutionary Caliber 9SA5, which offers a power reserve of 80 hours thanks to its enhanced energy efficiency. First presented in 2020, Caliber 9SA5 incorporates three significant developments, the entirely new Dual Impulse Escapement, the Grand Seiko free-sprung balance, and the horizontal gear train which, together, set a new standard in high-beat horology.

THE BASICS 
SLGH005 captures the dynamism of the white birch tree forests near the studio in Shizukuishi, where all Grand Seiko mechanical watches are crafted. To look closely at the dial is to experience the exact same feeling that the visitor to these forests receives and to be brought closer than ever to the true and eternal nature of time.
