The team of elite watchmakers from the Micro Artist Studio 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. In every external aspect, the watch is as striking as is the performance of the movement.

The case is Platinum 950 and just 9.8mm in depth. Both hour and minute hands and hour markers are made of 14k white gold. The Grand Seiko name, the minute markers and all the other markings are etched into the dial. The power reserve indicator is visible through the sapphire crystal case back, next to the barrel whose shape echoes the bellflower that is the symbol of Shiojiri, where the studio is located. The two bridges have edges that are painstakingly polished so that their brilliance contrasts with the perfect hairline finish of the bridges

The watch is offered as a limited edition of 30 whose design expresses the beauty of the natural surroundings of the Micro Artist Studio. The dial features the celebrated “Snowflake” pattern which is inspired by the beauty of the snow in the Shinshu region. The dial’s silver finish complements the delicate hand carving on the platinum case.

* Torque Return System: When the mainspring has been fully wound and the torque output is at its highest, approximately 30% of the available power is not needed to maintain the precision of the watch, and is in effect wasted in a normal movement. The Torque Return System uses this energy to rewind the mainspring, resulting in an increase in the power reserve.
