The Caliber 9F51 still has a regulation switch for manual fine-tuning of accuracy during servicing, a Backlash Auto-Adjust Mechanism to eliminate the shudder of the seconds-hand, and the Twin Pulse Control Motor, which generates the torque required for Grand Seiko’s large hands. It also has an accuracy of ±10 seconds per year (at temperatures between 5°C and 35°C). But now, the movement is 0.6mm smaller than the previous 9F61 caliber.
The rest of the package is instantly recognizable as the Snowflake dial that dates back to 2005 and its successor, the Skyflake, which captures the wind-swept snow shimmering beneath a clear sky. The case, bracelet, and three-fold clasp all come together in the brand’s signature Heritage Collection design. These watches will be available at Grand Seiko boutiques and select retailers starting in April, retailing at $3,200.
