I’ve have gmt I purchased pretty cheap, I’m wanting to do my 1st build a 126710blnr Batman gmt, I believe the movement is a dg3804 in the watch I have. I’m wanting to get a custom dial made and use some gen parts on it like bezel, hands, whatever else I can afford. from my understanding with that movement that’s not really possible. So my question comes down to the case what other movements can I use in the case?
