I recently kopped a vintage mint 6138 column wheel chrono. In my opinion, the 6138 (what many believe to be the first column wheel auto chrono movement) is the most robust vintage chrono movement. These watches look so up to date, yet are over 30 years old. I love it and my next kop will hopefully be a pristine 6138 Panda. The price on these vintage 6138's is a joke in terms of how cheap they are and how expensive inferior vintage Swiss chrono;s are. Seiko's heritage and manufacturing put most if not all swiss brands to shame. The Grand Seiko line is in a league higher than 95% of the high end Swiss watches.
My watch is same as this, but a smidgen more pristine (pics from photo database on seiko citizen watch forum):
