Grand Seiko is ending its 60th anniversary with the introduction of a steel on steel limited edition SLGH003 using the 9SA5 movement that launched earlier this year and is slated to be the foundation of a whole new generation of mechanical watches.
The Japanese watchmaker describes its Hi Beat 9SA5, with 80 hours of power reserve, as “without a doubt the finest mechanical caliber Grand Seiko has ever created”.
The movement, which is accurate to within +5 to –3 seconds, is used in a 1,000-piece limited edition that will go on sale in December for £8,650.
The 40mm watch is a three-hander with date that uses a deep blue sunray dial.
A sapphire crystal case back gives a perfect view of the 9SA5, which is finished with rippling waves reminiscent of the Shizukuishi River near the studio where the watch is made.
