The Atera Valley is one of the foremost places of scenic beauty in Nagano Prefecture. As the vibrant natural environment changes in expression throughout the four seasons, the clear waters form a singular beauty referred to as “Atera blue,” and enchant the hearts of all who visit them. Through a combination of highly transparent blue-green color gradations, this watch expresses the eternal flow of time evident in the formation of the valley. The case and bracelet are high-intensity titanium, a metal 30 percent lighter than steel and highly resistant to rust, corrosion and scratches.
