I don't know if Edward Green is a net importer or exporter. However, regarding its import of raw materials, it will be considering more than just the recent weakness in sterling. It has to consider potential future currency downside and the real prospect of import (and export) tariffs being imposed in the event of a "hard" Brexit. The business environment is rather uncertain at present. Risks don't always pay off.
Furthermore, I doubt that production is as easily scalable...
I have never been drawn to the minimalist aesthetic of Nomos. It tells no story to which I can relate. I don't like Skagen watches either. Or Ikea furniture. Somehow these things don't seem REAL, as if they are empty models of reality instead of reality itself.
^ I don't think it's silly at all. Clean, simple design, avoiding unnecessary fuss. Chunky brushed gold, wide milling on the bezel, solid and straightforward lugs. The black strap and dial work well with the gold. It's what Rolex would have made in a steampunk parallel universe. A keeper.
