Munich it was, and yes they were very spicy indeed!
Congratulations on your watch! It looks very good. Of the two styles of the P Sub featured, I prefer the case and dial that you got (the one on left in my picture).
However, I did not notice the odd spacing between the letters you refer to while in the shop but now that I see it I also think that it is remarkable that something like that would pass quality control (at least it would be unacceptabel in todays' market, but I do think QC was slightly more loose back in the 50-60'ies). Also, from the previous post that I refer to in my post above, I get the feeling that UG's from that period are not amongst the most consistent of models as there appear to be several different seconds hands applied and also the inner bezel is sometimes with lume on the first 15 mins and sometimes not - and I believe that both versions are correct.
Your watch looks ok to me - but I am not an expert (which is why I posted on this subject in the first place )
All the best
Nikolaj
