Saw this Tissot Astrolon go through auction earlier. It has a bit of an interesting history in as much as it was gifted by a Tissot Director to Roger Horstmann ( deceased owner of Horstmann Gear, manufacturers of electrical timers, plumbing valves etc in the UK ) What caught my attention was i've seen these with " Idea 2001 " and "Astrolon" even "Research" written on them but not "Switzerland"
