This is a calibre 911 flightmaster from the 1970's. It was designed for pilots and feautures a number of really useful functions including a rotatable bezel, a GMT hand which can be set independantly (blue hand on pictures) and a chronograph function.
I have been after one of these for quite a while and gave up the chance to own one when 'The Master' offered me this particular piece which i turned down and another friend Torbjorn bought this piece instead. Well fast forward 6 months and Torbjorn had found another one, so offered me this one at cost price! finally a flightmaster in the collecton thanks to Torbjorn and the Master indirectly.
Here are the pictures:
