Brief description: Stainless steel barrel-shaped men's self-winding wristwatch.
Round black metal dial with white painted Arabic 24-hour numerals every second numeral (starting at "2" marked with a luminous (tritium) dot for hours chapter; below that is a minute/seconds track marked at 5-minute/second intervals; there is an additional orange 24-hour adjustable revolving outer track that can be set to a second time zone by the crown at 2 o'clock, date window at 3 o'clock, dial marked, GLYCINE AIRMAN, SST, AUTOMATIC.

Producer name: Glycine Watch Company
Production date: Circa 1970
Made in: Europe, Switzerland
Dimensions: 41 millimeters (case)
Dial: GLYCINE AIRMAN, SST, AUTOMATIC. T SWISS T.
Movement: 17 jewels, ZERO ADJUSTMENTS
Case (inside): Patents 314 050 323 1219 (Curator's note: 31450 is the 24-hour bezel patent by Glycine, 323 identifies the movement as "A Schild 1903 caliber, and 1219 identifies the case reference number.)
The Glycine Airman SST-06, sometimes called the "Pumpkin" was first introduced in the 1960s and was a favorite among helicopter pilots during the Vietnam War.
"SST" stands for "Super Sonic Transportation" being developed by Boeing 733; the Glycine Airman was inspired by Boeing 2707, which was inspired by the British/French Concord, and the Russian Tupolev, the first 1 Mach passenger jet.
This watch uses a modified A. Schild 1903 movement, with a real 24-hour movement; the hour hand makes one full turn every 24 hours.
The hacking function is somewhat odd. When you pull the crown, a very, very tiny hairspring is pushed through a very small hole between the 2 and 4 of the 24 marker, thus stopping the second hand! Patent No. CH323890 was applied for in 1955 and granted in 1957.

With the lilt of Irish laughter
Every day and in every way
Now forever and ever after."
