An AGR Plans Officer for a Reserve training division at Fort Knox. "Waiting in that sketchy PX to get a haircut. Anyone who's been there knows that the barber in the background will cut you!" On the wrist, a 1970 Seiko 6105-8000. What's the sketchiest barbershop you've ever waited in on post? If you have a wrist shot from somewhere that matters, submit at the link in bio.

Seiko 6105-8000
The 6105 followed Seiko's first dive watch, the 62MAS of 1965, and the 300 meter 6215 of 1967. The 6105-8000 is where it began, around 1968: a more symmetrical case, a crown at 4 o'clock with no crown guard, and a bezel that turned both ways without a click. The later 6105-8110 brought crown guards, and a 6105-8110 is the watch Martin Sheen wore as Captain Willard in Apocalypse Now.
Every 6105 ran a 17 jewel automatic beating at 21,600 vibrations per hour, with 150 meters on the dial. The early 8000 used the non-hacking 6105A calibre; the hacking 6105B came later. The 8000 was the version for most of the world, while the US market got the 6105-8009.
In the Vietnam era the 6105 was one of the watches servicemen bought for themselves at the PX rather than wore as issue.
