To me, a frankenwatch is a watch cobbled together from many different parts, that someone then tries to pass off as the genuine article. You are not doing that.
What you are doing is building a "kit watch" or a "project watch"; you're taking an old watch, and restoring it with as close as you can get to original parts, but with one or two compromises along the way. It's a custom piece. And having different hands doesn't devalue it; in fact, quite the opposite. Your watch is one of a kind. Lovingly restored by someone (YOU) who loves horology. There's nothing wrong with that; in fact, there's EVERYTHING RIGHT about that! 😀
