Any recommendations for more affordable 'Concept Watches'?

Hi OF,

I was looking for some recommendations, preferably more affordable alternatives, for what I think would be called 'concept watches'? Watches that may have some or all of these characteristics:

- made in 'non-traditional' non-metal materials (i.e. synthetic)
- on rubber/silicon straps
- 'non-traditional' in movement construction
- quite often open-worked-dials.

I personally really like the aesthetic of the AP concept watches, as well as:

- many of the De Bethune watches
- Ulysses Nardin Freak
- JLC Extreme Lab
- I'm not a huge of the Frank Muller and Richard Millle Tonneau shaped pieces
- Not a huge fan of Hublot in general

Does anyone have any experience with anything else similar? Some of the pieces I've listed above are just completely out of my price range, looking for something in the $10-20k ish range? I know seven friday is probably a good affordable comparison, but I was looking for something more high end, and also I know some of the entry level UN Freaks are actually cheaper now!

Thanks, some photos below

Singer or Ressence both have a different take

Look at the JLC Amvox line. Some of them have similar looks to the Extreme Lab. Or something like a Zenith 21.
