So I bought a 2 tone A21j rolex sub from an RWG member. Worked fine for the first couple days I owned it. Now I have a bit of a perplexing issue, hopefully you guys can point in the right direction with.
If I wind the watch or turn it a few times to get it started and I have the crown all the way screwed down, the watch will work for between 10secs and a minute before the second hand stops ticking. However, if I do the same to get it started and I leave the crown completely unscrewed down, then the watch works fine like it is supposed to. What kind of issue am I looking at here?
I am a relative newb to this, so would it be worth fixing (by either myself or someone who knows how to operate on it), or better to just buy another?
