An automatic five-day Spring Drive model inspired by Lake Suwa stirred by an early morning breeze.
For Grand Seiko, the natural environment of Japan is an endless source of inspiration. Grand Seiko dials often evoke the uniquely Japanese beauty of the very places where its watches are made. And one body of water to the southeast of the Shinshu Watch Studio, the home of Spring Drive, is a perfect example.
