I bought my Vertex watch from Exchange and Mart in the early 70’s, if I remember correctly for abut £5 10shillings and sixpence.
It is one of the dirty dozen watches. I also have a Cyma issue as well. These were the first wristwatches specially commissioned for the British Army during the Second World War. I do like Military or Aeronautical watches. My favourites being Heuer Pilot Automatic and a Marvin Flying Dutchman watch which were issued to KLM Pilots in the 1950’s.
I love the dirty dozen watches. My only reservation is usability (waterproofness etc.) that is why I suggest the modern re-issues like Vertex, Bremont and Smiths.
I had never seen that Marvin although I know of the brand! It looks a bit like the Universal Geneve Pole-Router, a watch designed for the S.A.S (airlines) to celebrate them flying over the North Pole I believe.
