If so, some that the others have mentioned like Urwerk and MB&F stand out, as do several other higher end manufactures like Akrivia (the AK-06). Coming down a little in price point how about Ressence? And then lower price points again Azimuth, Gorilla or Seven Friday.
You could always look back, to the 60s, 70s etc when Seiko, Omega, JLC and many more has more unusual cases and dial colours. Plenty that might meet your hurdle there too.
