Masterpiece Collection Spring Drive Caliber 9R02
The silence and beauty of a snow white world
Caliber 9R02, created by the Micro Artist Studio, is a manual winding Spring Drive movement that has two mainsprings set in parallel within a single barrel and uses the Torque Return System to deliver a power reserve of 84 hours. It drives a slim and elegant watch whose whole design is inspired b the landscape that surrounds the studio's home, high in the mountains of central Japan. As the glide motion seconds hand sweeps across the pure white snow-patterned dial, the wearer will feel the natural flow of time in winter and the beauty of our natural world in its purest, pristine state. With its lasting precision, the elegance of the manner that the natural flow of time is presented and with the eternal beauty of its design, this unique timepiece expresses Japan's fascination with both the ephemeral and eternal qualities of time.
