Authentication Notes
Combination
'Pogue' is a dial colour, not a reference
Yellow-dial 6139-6000, -6002, -6005 and -6009 examples are all commonly sold as 'the Pogue'. Any listing that presents one reference as uniquely the astronaut's watch is overstating: the watch flown on Skylab 4 was a 6139-6005. Treat the nickname as a description of the dial and price the reference and configuration on their own evidence.
Dial
A jewel count on a -6002 dial is a North American dial
North American -6005 and -6009 dials state '17 JEWELS' beneath the hands and read 'AUTOMATIC' rather than 'CHRONOGRAPH AUTOMATIC'. A -6002 case carrying that dial has had a dial change. Both parts are genuine Seiko; the combination is not the one the case left the factory with.
