Awesome!
I've heard that sometimes dials are attached with sticky pads, but I'd hazard a guess that soldering is more effective. I've never had either done, so maybe talk to someone who has done it? I think there is some negligible risk of damage to the face of the dial.. but really, you want to talk to someone who has done it.. maybe Archer, Horlogerie, Christian (who did the work in that link).
