The only names you're going to find associated with the area (i.e. the Balkans) are for vintage/resurrected brands such as Darwil (Swiss, but had a facility in Trieste so in the Italian Balkans), clock (not watch) companies such as Insa (which mostly do gauges and dials now), and defunct brands such as Mestis (which appears to have used ebauches from Poljot and 1MWF).
