Seiko Tungsten

The Seiko 6139 was one of the first automatic chronograph movements ever made. It remains one of the most interesting and undervalued vintage watches today. What do you know about this iconic Japanese watch?

I don’t like to praise a brand at the cost of other brands, but Seiko and Grand Seiko almost lure me into doing this. When asked to choose between a famous Swiss brand from the Valley or Grand Seiko, my answer is different today than it would have been before 2015. In 2015, I visited the Grand Seiko manufactories in Japan. It was an eye-opener, as they say.
