The SBGC205 is the most complex Grand Seiko ever made and combines many different functions with the highest possible level of craftsmanship. Unique to the 205 version is full titanium construction, making for a much lighter watch, and yellow gold accents throughout the dial. It uses the 9R86 spring drive, Grand Seiko's most sophisticated movement, which has chronograph, GMT, date and power reserve complications. As a result, it's just as incredibly accurate as any other spring drive but has a much higher degree of functionality. As if that weren't enough, the 9R86 is also Grand Seiko's most beautiful movement.
The SBGC205 is the updated version of the SBGC005.
