The 1970s Glycine Airman ‘Pumpkin’ SST vintage pilot’s watch was a premier choice by jet pilots in the era. These SST watches are less common than the earlier Glycine Airman models. This watch allows the owner to keep time in two different time zones. The hands only rotate once a day and display military time. These watches are large in size, measuring a massive 42mm across. The two-tone (A.M.-P.M.) dial is original, as are the hands. The case is in very fine shape overall, with both crowns being original. The original bisected black-and-grey dial has the original hands and lume, which are very clean. The movement with the (pull out crown) hacking function is working perfectly. The Glycine Airman SST was used by many jet pilots throughout the world, due to its easy-to-read dial and handsome looks. This watch comes with the original bracelet.
