Greetings Katt- I have a pretty high-quality Rolex Explorer II replica. I have had the watch for about 6 years and about a month ago it stopped working, assuming the movement needs service/cleaning. General question - which is why I post for board as well - since it is replica would a person be better off to just purchase a new rep (with newer movement) in the $500 range or if you service the older movement (which I think is 3186) would that give another 5+ years life to a watch that is 6 years old? Thank you!
