Sport GMT 25th Anniversary

From the retailer listing

A new limited-edition watch commemorates the 25th anniversary of the Caliber 9S mechanical watch movement. The new GMT watch lifts the imagination skyward with a beautiful blue dial that illustrates a sea of clouds at daybreak. In the early morning, humid air forms dense clouds that overlap to create a beautiful tapestry in the sky. The shade of blue is inspired by the sky over Mt. Iwate when it is blanketed by this sea of clouds. A rotating sapphire bezel in blue and white elevates the design while allowing for a total of three time zones to be read at once. Inside is the Grand Seiko Caliber 9S86. Assembled at the Grand Seiko Studio Shizukuishi by skilled craftsmen and women, the Caliber 9S86 beats 10 times per second, enhancing rate stability.
