Glycine Airman

Vintage Glycine Airman history,Vintage Glycine Watches,Glycintennial

The letter that started it all: Glycine Airman

Samuel Glur and Ched Brown

In 1953 summer, Samuel Glur, Sales manager for Glycine was on a business trip covering Southeast Asia and Indian continent. He arrived from Bangkok to Calcutta and wrote a letter on 14th of July 1953 to Charles Hertig, the owner of Glycine Watch Company. His 5 pages letter was a sales/activity report and feedback from clients. What is important for us is in the 3rd page of the letter as pictured above. It contains feedback from Captain Ched Brown who flew a DC4 at Thai Airways, whose suggestion led to the birth of Glycine Airman. 

Glur wrote that the Chinese clients in Thailand want 1,500 ETA 7,3/4 size movements and that if ETA won't or can't supply, that they should find good movements after the holidays.  

Then he proceeds to write that during the flight from Bangkok to Calcutta in a DC4 type aircraft of Thai Airways he was able to travel in the cockpit. He was seated at the first officer's place next to Captain Ched Brown and was able to talk with him about watches ( Ched Brown's name is also mentioned in early Glycine Airman manual's service coupon where the Airman is illustrated in a birch-wood box, Brown's name of sender and his title is written on the box). Captain Brown told him that there is no watch that meets the need of pilots and shared some specifications what he believed pilots from all countries would love. Samuel Glur took note of captain's feedback:


  • Waterproof & Automatic & Calendar
  • 24 hours dial
  • Hour hand revolves 360 degrees once in 24 hours
  • Minute hand revolves 360 degrees once in 60 minutes
  • Seconds hand revolves 360 degrees once in 60 seconds
  • An external rotatable bezel that is divided in 24 hour units 


Captain Brown said that since more and more pilots were flying on GMT time that this watch would enable flying personnel to track both local time and GMT. Glur added a note at the side of the letter that Felsa 694 with 21 jewels may be a correct movement to work on.


Client feedback was taken serious back then, he returned to Bienne and the two, Charles and Samuel start working on the design and prototypes Ched Brown suggested. They decide on the name 'Airman' since the idea came from an airman and this would be the ultimate tool watch for pilots around the world. 

They obtained their dials, case and movements, modified and assembled the first Glycine Airman to test. In the meantime they kept Ched Brown updated of their progress since he and his colleagues would be the first clients. After initial successful testing they applied for the famous Airman patent CH 314050 on 2nd Dec 1953. The patent marking CH 314050 remains on the case-back of thousands of Glycine Airman watches manufactured since then. Glycine shipped the first batch of Airman watches before Christmas 1953. The manufacture parties were varying from 25 to 1,000 pieces due to export destination. Some military units wanted their own insignia on dial, so did retailers. Glycine met all their demands and gave them the joy of being part of this invention.

That's the story of this legend's birth, the Glycine Airman.

Glycine Airman in 1953 and 1954

Vintage Glycine Airman patent,Vintage Glycine Watches,Glycintennial

CH314050,the patent of Glycine Airman's rotating bezel and the clamp crown which locks the bezel in certain position.Late '40s and early '50s are full with inventions of universal or time zone watch patents,so they were called back then.It's an interesting period to study through the patents.Most companies including Rolex have focused on rotating discs with city names on it.Glycine got it right. 

Vintage Glycine Airman,Vintage Glycine Watches,Glycintennial

The very first Airman were simple 24h watches with a rotating 24h bezel,enabling the user to read two time zones with the hour hand at a glance. This was much more practical rather than having a 12hour watch with 24h rotating discs with city names on it.It fixed a problem in the market, that's why became so popular. It cased a Felsa 692/N movement. It retailed for USD 51,95.

Patent markings on case-back indicate the Swiss patent of Airman. Earlier models have 'Model Depose 'mark indicating that it's applied for but pending it's registration. The Glycine Airman until March 1955 had no hacking mechanism and no magnifier on the date window. The hands were also generic from its time dauphine or pencil style hands without any tail-ends.

Stopping the seconds hand at any needed time to synchronize time was and is important especially in coordinated military exercise. Every second is important to start, to stop, to drop, to attack...Many companies already had patented ways to hack the seconds. When something was patented it was exclusive for the patent owners to use it. Glycine found this very unusual way of stopping seconds with a pin popping up onto the dial when crown was pulled-off. This spec has been used only by vintage Glycine Airman and Glycine Combat watches, no other company has it, making it another unique touch-point.

In March 1955 the patent for seconds hacking has been implemented on Glycine Airman watches and improved on Dec. 1955 with another patent.

The hacking seconds wasn't the only change: Airman got a modification on the hands, extending a tail-end on the minute hand and a date window magnifier. New features were shared in the manuals of the watches.

This model was the outcome with added features in mid-1955. It came in beige and black dial. Bezel numbers configuration was also varying and could be tailor made while ordering. You could have 2*12 hours, even and uneven numbers....These models surface very seldom in the market, but are still around. Glycine, during their manufacture from March 1955 to 1972 of mechanical Airman watches have always used this seconds hacking mechanism. The only model which doesn't have this spec is the vintage Glycine Airman with A.Schild 2163 movement which was manufactured in '70s, the movement itself had a seconds hack mechanism.   

The hacking mechanism

Vintage Glycine Airman hacking mechanism

If you intend to buy a vintage Glycine Airman make sure the hacking mechanism is working. The hacking pin pops onto the dial at 24 o'clock position between the digits 2 and 4 when the main crown is pulled-off. You will need to wait until the seconds hand reaches 24 o'clock position to stop . At this position the watch will 'still marche' for a few ticks and will stop. Balance wheel will stop also. Once the crown is pushed back in, the pin is lowered and the seconds hand is moving again. That's how the airman synchronized their watches with the signal from the air-base. The pin is attached to a lever which is in the watch-case and operates through the main crown. A simple but efficient solution. Having something unique in your watch is wonderful but it has some down sides. Many watchmakers are not aware of this specification and therefore can't make a sense of it and damage it. Many Airman watches have damaged hack mechanisms, some have been even removed by incompetent service centers. Today we are able to re-store this mechanism.

    Tailend moves to hour hand

    In 1957 the tail-end has been switched to the hour hand. The tail-end is enabling the wearer to read the time in 12h format when it's PM. Until 1961 all vintage Glycine Airman watches have triangle hour markers at 12 and 24 o'clock. Airman with 23 Jewels is retailed for USD 96,80 for AOPA members, USD 121 for non-members.

    Glycine Airman crowns, jewels and movement

    This period vintage Glycine Airman watch crowns are plain without any patterns. 'Special' models are manufactured in this period to export to the US in order to pay less taxes due to ' the more jewels, the more tax' regulation. The 23 jewels Felsa 692N has been reduced to 17 jewels in these models. Airman Special at this time is USD 79,20 for AOPA members and USD 88 for non-members.

      There are several changes from 1964 and onward. With Glycine and Altus merging in 1963, opening a service center in the US in 1964, Charles Hertig Sr., the owner of Glycine passing away in 1965, Glycine evolved into the situation. With the experience of Vacuum and Compressor watches in the meantime, Glycine also applies the success of compressor cases to Airman models. The way of numbering on case-back is also changing. Vintage Glycine Airman is retailing at 99 USD in 1964 and at USD 100 in 1967 with stainless steel bracelet.

      Cases have been switched to EPSA compressor cases. Ervin Piquerez SA was a casing partner for Glycine. He had his hey days in the '60s and '70s with his compressor method which gave the aviation and dive watches durability.

      Vintage Glycine Airman SST watches

      Glycine Airman SST was introduced in 1967. Supersonic Transportation  ( SST ) became a goal for humanity. Glycine took an orange approach as the color of future. These watches were still EPSA cased and would have the hacking mechanism at 24 o'clock. SST cases are larger than classic Airman watches while the shape has taken an aerodynamic design. The movement utilized in SST is A.Schild 1902/03. Airman SST has a two tone black dial for AM and PM hours. When it was introduced, it retailed for USD 82 with leather strap and USD 89 with stainless steel bracelet.

      Future with SST was fast and sophisticated as in the video most below. Glycine as a trendsetter in aviation timepieces has introduced these bold designed Glycine Airman SST chronographs in 1969. It was a limited run and only 100 watches were manufactured. This timepiece is powered by Valjoux 724 manual wind chronograph movement. If you have one hold onto it since it's very rare to surface. While the crown and pushers at the right side of the case operate the totalizers and hour recorder, the left crown operates the rotating internal bezel.

      Glycine Airman and the Supersonic age

      The Supersonic Transportation stimulated future life. That's how they imagined it in 1975 ( custody of Braniff & Popular Science ):

      Glycine manufactured its first Airman Quartz timepieces in on 11th Mar 1979. These were powered by ESA/FHF 960.111 movements. The manufacture was for 3,000 pieces. Interest was high and it was sold out pretty quick. But for some reason Glycine didn't want to make another manufacture party. This led Werner Siegrist to negotiate with Glycine to produce further Airman Quartz watches under his own brand ' Falcon'.

      Within the new-er herd of Airman watches most were tribute models and differentiated in size and movements. However some had its own specs like never before Airman Double D 24 with a complicated ETA 2893 movement and a Soprod 2424 module on it to power 5 center hands., Airman 7 with three movements in watch-case and three separate dials, Airman Airfighter with an innovative sliding button are some of them. Glycine manufactured in 2013 Airman AM/PM tribute model, than in 2016 came Airman 1 in its original size 36mm of vintage Glycine Airman. After 2017 it looks like Combat has the focus and is being diversified.
