    NOW ON HOLD PENDING FUNDS

    Hi All,
    Something has cropped up and I’ve decided to sell my small collection of four, all original Glycine ‘Airman’ watches.
    I originally listed these as a 'set' of four, but due to Forum rules, I will now be listing them separately over the next few days.
    They are all vintage watches from the 50's and 60's, not the re-issues.
    These are 24 hour watches, however the extended tail of the hour hand also points at the 12 hour equivalent during daytime – pretty neat.
    They are all automatic self winding movements with a date feature and all have ‘GMT’ rotating bezels which can be released and locked using the second ‘crown’ at 08.00 hours..
    Stainless steel cases just over 36mm without crowns with 20mm lug width which makes them ‘wear bigger’.
    All are in excellent condition for their age - Clearly they show signs of being worn, but no major dings or gouges.
    They all feature the remarkable ‘hacking’ seconds hand complication.
    For those new to Glycine Airman’, the hacking seconds is an astonishingly simple mechanism, unique to Glycine Airman, which allows for ultra accurate synchronisation for individual or multiple timepieces.
    There is a tiny hole in between the 2 and 4 digit at the top of the watch dial.
    When the crown is pulled out to the 1st position (time setting), a cam mechanism pushes an ultra thin wire (human hair thickness) up through the hole.
    The second hand continues to rotate until its extended tip comes into contact with this wire, and it stops. Once hours and minutes are set on the watch, the seconds hand is immediately restarted at zero, by pushing the crown back in to manual winding position (thus retracting the wire and allowing the seconds hand to start).
    For example, in a military context where ultra accurate synchronisation was essential - a large number of pilots during pre flight briefing could very simply synchronise all their watches by pulling out the crown, setting the time - and then after a countdown, simultaneously pressing the crown back in – all seconds hands would start in sync.
    This feature was used extensively during various conflicts including Vietnam.
    Unfortunately, many of the vintage Glycine Airman watches that come up for sale, have non working hack mechanisms, parts are no longer available so repairs are quite challenging.
    Although not a major target for ‘fakers’, there are a few out there – and quite a few ‘frankens’.
    Here are some links to more information on the Glycine Airman, much more info is available on the net.
