So after about 2 years of buying reps, started with cheap reps from China town in New York to now getting the best of the best from TC, Angus, Toro, etc. I have decided to take the jump and start making some of my own repairs and band replacements. I have a decent GMT II Blue Dial with Blue Ceramic insert. It's probably the nicest rep I got from my days of buying reps in China Town NYC. I'd like to replace the movement as the watch has recently stopped working. I am looking for a bit help.
what movement should I replace it with?
Where is the best place to get movements?
is a friction ball good enough to remove the back and put it back on properly? Or should I invest in some proper case openers?
Any other help or guidance would be greatly appreciated.
