Devon Works Tread 1. I don't know what to make of it but certainly interesting to say the least: https://www.hodinkee.com/articles/a-week-on-the-wrist-the-devon-works-tread-1
Yup. Super neat I've seen them in person. I wouldn't wear one but neat execution super high quality. More here http://www.ablogtowatch.com/watch-brands/devon/
Haute Horology to me is a very strange area - most of the creations are ludicrously expensive, very limited editions that often times have very limited appeal in their appearance, though technically interesting. There are evidently lots of people out there with a large amount of discretionary income to purchase "watches" with an extremely limited market.
