In Nagano Prefecture, where Spring Drive watches are manufactured, there are several mountains that rise to over 3,000 meters in altitude. The countless rivers that flow from these mountains have created a lush, natural environment over many years. The Atera River carves a deep ravine called the Atera Valley, which is renowned for its breathtaking beauty. Using the clear, emerald-green waters of the Atera River as its motif, the dial evokes the image of a stream so clear that one can see the bottom, as well as the rich, natural harmony of summer. At the heart of this timepiece is the Caliber 9RA2 Spring Drive 5 Days. This movement provides up to 120 hours (5 days) of power when fully wound, as well as an average accuracy of ±10 seconds per month, an astonishing feat for a watch powered by a mainspring.
