The SBGE205 features what Grand Seiko calls their most complex dial ever, the product of a lengthy 12 step process. It has the 9R66 spring drive movement, which adds a GMT hand for tracking a second time zone. Like all true GMT watches, the hour hand is independent. The spring drive technology inside combines mechanical beauty with better-than-quartz accuracy, making it arguably the most sophisticated movement technology in the world.
The SBGE205 is the new version of the original SBGE005.
