Mechanical Hi-Beat 36000 GMT with a hybrid of blue ceramics and high-intensity titanium

This is a next-generation luxury sports watch that uses ceramics and high-intensity titanium for the case and bracelet.
The blue design motif resonates through every element of the watch. Complementing the dial in Grand Seiko blue are the Arabic numbers hour makers at the 6, 9, and 12 o'clock positions and 24-hour hand. The bracelet and case are also executed with blue ceramic elements.
The strength of the ceramic parts is balanced by lightness of the titanium to ensure that the watch is supremely comfortable to wear. Because of its light weight and its superior water resistance, the inner case is also made of titanium.
Differences in light intensity and light source result in complex changes in color, so you can enjoy a variety of expressions.
This watch houses the Caliber 9S86, the high precision 10-beat mechanical movement.
