As a long time Lemania collector and now a Heuer collector, it may be obvious that I am going to be looking for similarities and drawing comparisons to the two brands. The similarities in movements has been well documented on this forum. I picked up this Lemania recently and it is in an identical case to my Heuer Audi Sport. The bracelet is identical, so is the crown and pushers, apart form the obvious dial markigns, they are the same - the dial is from the same press with the same luminous markings, tach scale etc. The movements are both Lemania 5100, but the Heuer is the variant without the 24 hour hand or the day wheel. Interesting comparison, and I am sure these came out of the same factory at the same time.
