I very much doubt these were the 'True Pogues' that the O.P stated ?
There's a big difference between a Seiko 6139-600X and a 'True Pogue' 6139-6005. The 'True Pogue' has to have several things.
Automatic only Japan 6139-6009T dial, water 70m resist, and 17J with Suwa symbol above the subdial. The dials are also a lighter shade of yellow, and if you want to be anal it should be a 19xxx serial dating to Sept 1971, or very close.
At a guess I would say for every 300-400 6139-600X's you see sell, there maybe 1 True Pogue.
This is one.
