I inherited a Rolex similar to the GMT Master above from my father in law who had been a pilot all his life. According to what I read, it was the first Rolex “pilot’s watch” and the result of collaboration between PanAm and Rolex to develop a watch to help with jet lag. The result was (ta daaa!!) the rotating bezel, so the pilot could keep track of the time in his own time zone. Seems laughable now!!
Anyway, I have been wearing the watch for a good few years but now it has started losing so much time that it really is just jewellery – and right how I can’t find the 500 quid to stump up to get it serviced, which is a pity.
