MANUAL-WINDING SPRING DRIVE
Caliber 9R02
"A new Spring Drive masterpiece from the Micro Artist Studio.
The Micro Artist Studio made its first contribution to Grand Seiko with the 8-Day Power Reserve Spring Drive watch that was greeted at Baselworld 2016 with great acclaim.
This same elite team of watchmakers now presents Caliber 9R02, a new movement that has two mainsprings set in parallel within a single barrel and uses the unique Torque Return System to deliver a power reserve of 84 hours."
