Herology on Twitter: "1975 Seiko 6139-8020 “Hexagon” 17 Jewels Chronograph around 39mm wide w/c and 12mm thick which makes this “Speed Timer” much more compact compared to the venerable “Pogue.” 👍👍👍 #Seiko #
A '71 Seiko 6139-8020 - the watch that got me into vintage Seiko. I bought the watch itself from Argentina and the NOS strap from Saudi Arabia. : r/ Seiko
