Thank you for this! There is simply no other archive or institution with this kind of resource online! I'd been through the catalogs but no knowing what year it was from, the process was a little daunting.
The plot does thicken, however - It seems that I have a 12-hour GMT hand but a 24-hour case/bracelet? Is this correct? My GMT hand is also an arrow, which seems to be different. This is all very strange considering that the watch came with box, papers, etc.
Edit: The arrow hand appears from be from the 87/88 catalog, although mine is branded Heuer and still features everything but the 24 hour movement.
Not to mention, the case ref # is for the 24-hour version (895.413) - is it the same movement and an adjustment or what?
