The GLYCINE AIRMAN vintage military watch was used in Vietnam and was popular among military servicemen and pilots everywhere. From the 1950’s to the 1970’s pilots have relied on the AIRMAN due to their bold and easy to read 24 hour dial. These dials display both 24 hour time and conventional time at the same time. This 1960’s GLYCINE dial is very clean, all original The lume on the hands was updated many years ago. Notice the early and uncommon red date. The unpolished stainless steel case is in exceptional shape and retains the original turning bezel, along with the original (early 60’s version) screw-back. The lower crown locks the rotating bezel. The automatic winding, signed FELSA 892 was recently (expensively) cleaned. These watches are becoming hard to find in original condition. Many are not aware, GLYCINE AIRMAN watches have a hacking seconds feature. When the crown is pulled out a hollow tube shoots up a microscopic wire at 12:00 stopping the second hand when it reaches 12:00. This hacking seconds feature is working perfectly. Please also note. PARTS TO FIX SECOND STOP ARE NO LONGER AVAILABLE…they sold out 2007. Due to the desirability of the GLYCINE AIRMAN, there are FAKES out there… many are getting scammed-be careful, especially on eBay. This truly is a prime and hard-to-find example.
