I'm actually quite curious about these brands myself, read a lot of good comments about Dornbleuth's workmanship and Habring winning numerous awards. The closest retailer I can think of for these 2 are define watches in australia, they carry quite a number of German brands besides these 2, can order online. I'm not sure about Habring2, but iirc Dornbluth's movements are heavily modified unitas 6497/6498 based manual winds, should be fairly straightforward for any reputable watch repair center to service.
