How satisfied are you with the quality? I looked at the watches of Sternglas some time ago and only the Kanton 2.0 appealed to me. For the price of the Hamburg, I would buy it, but since it costs twice as much, it's a bit too expensive for me.
Five years on my Hamburg Automatik, runs solid. Of course after loading up with shitters I wear it less often lately. FYI they show up used on Ebay for half price or less from time to time, set up a search alert.
