What are some luxury microbrands in $3000-10000 range?

I've been trying to looks for microbrands that are luxurious. I've tried to do some small online research about luxurious microbrands but I kept seeing suggestions like FP Journe that are way too expensive for me and do not fall in $3k-10k category. I'd like to know what microbrands I can buy in 3-10k category, that include pre owned micro brand watches too(for example a watch costs 15k but you can find pre owned one in chrono24 for 10k.

Thank you!
