1970s Glycine Airman automatic. This is a very collectible watch which shows 24 hour time. The hour hand makes only one revolution per 24 hours. The dial is divided to am and PM hours. The pumpkin color inner bezel can be set by turning the smooth crown. This watch has an interesting hacking ( stopping the second hand ) feature. When the crown is pulled out for setting the time, the second hand will be stopped when it reaches 24 HR position. This is accomplished by a very thin wire which comes out through a tiny hole above 24 numeral. The bracelet is aftermarket. LOT#3S5
