I'm looking for someone Europe based that can do my tri-compax as well. We should start a pinned service listing post
The watchmaker nearest to me (North Portugal) used to have a Tri-Compax or two so he should know his way round them. I haven't needed to take mine to him yet, but I'll ask him. He's been working on a few other watches for me, so I'm still finding out about the quality of his work. 3rd-generation watchmaker, FWIW. I'll keep you posted.
