A while back I posted about a mystery logo and had a few very helpful replies - thanks especially to Hartmut for telling me about Guba watches, a brand I'd never heard of. I suspect the the mystery logos must be some evolution of the Guba logos - perhaps a son? There's the 'B,' pretty plainly, but then there seems to be another letter, which variously and 'S' or maybe a 'W' or 'E.'
But looking deeper into the mystery, little seems to be out there. There's Ranfft's page. There's Christoph Lorentz' page. There's Mikrolisk. But in all of this, there's hardly a word about the actual company. Anyone know anything more about them?
