Hey Seiko fans,
On page 111 of April's Watch Time, they discuss the 6139 chronos. Then in the last paragraph they go on to say:
"The next year [1970], Seiko introduced Caliber 6138, with an added hour counter. This watch accompanied the astronaut William Reid Pogue on the SkyLab 4 mission 1973, earning Seiko the added distinction of being the manufacturer of the first automatic chronograph in outer space."
Eh? The 6138 was the Pogue? From everything I've ever read on the subject -including the documentation from Col. Pogue himself- shows the (yellow-dial) 6139 with 30-min counter only as the true "Pogue".
Did Watch Time get it wrong?
