Seiko has many master craftsmen creating their watches. On a recent tour of the United States for the launch of the Grand Seiko watches in the US market, we had the rare pleasure to observe one of these watchmakers at work. Jumya Kamijo has worked for Seiko for over 25 years. He studied watchmaking in Geneva, Switzerland to hone his craft. It's a rare pleasure to see his work demonstrated. And the two videos below give you a brief glimpse into what skill is required for working on these fine watches.
