As the title states, what non-metallic (plastic, ceramic, carbon fiber, wood, etc) watches are worth buying or knowing about? Probably going to be lots of adventuring stuff - so fake bonus points for non-sporting watches - but if a Pro-Trek, G-Shock, or Suunto is what you like and think every person should know about, post it up.
I’ll get things started with a classic, just to get it out of the way…
Right now, it appears to be a one off prototype some dudes are making to basically be a smartwatch in the body of an F91W. I just googled F91 Kepler like it says at the bottom of the picture.
