The Spring Drive U.F.A. Caliber 9RB2 achieves an exceptional annual accuracy of ±20 seconds through advanced manufacturing, a three-month-aged quartz oscillator, and a newly designed low-power IC. Each oscillator is individually measured across multiple temperatures, with thermo-compensation data programmed into the IC. Vacuum-sealing the oscillator and sensor protects against external influences, ensuring long-term stability, while a newly introduced regulation switch allows fine adjustments during after-sales service. The dial is inspired by ice forests, featuring a pressed pattern and a silver-tinged blue tone, accented by a tempered blue seconds hand. The compact movement enables a 37mm case, the smallest yet powered by the 9R series, ideal for smaller wrists. A newly developed, tool-free three-step micro-adjustment clasp allows precise 2mm adjustments for enhanced comfort. The movement is visible through a sapphire crystal case back, with finishing inspired by the winter landscapes of Shinshu, reflecting the understated elegance of Grand Seiko craftsmanship.
