Mid Range to High End Watchmakers For Microbrands?

I am looking to start my own microbrand. I have been so far unable to find a watchmaker online that makes good quality watches for microbrands. All I have been able to find is cheap garbage on places like Alibaba. And places that do make better quality stuff are microbrands themselves and aren't interested in making watches for what will essentially end up being their competition. Could someone tell me where microbrands who don't do the manufacturing in house get their watches made? I'm looking for something specific like a company name not something vague like Switzerland or China. Thank you for your time helping me with this.
