a7750 / tag aquaracer playing up :(

[scoobyc]

I've had my aquaracer day/date from pt since september and worn it most days with no probs but had a couple of probs recently and would appreciate any help! After 3 months, it would only work if i wound it rather than wearing it so took the back of and found the rotor screw had fallen out and so had the rotor. Reattatchd this and seemed well for last 6 weeks (this bits only added for completeness). Now over the last week it seems to stop for no apparent reason. The first time i checked the rotor and all was fine, hand wound it an nothing. I then pressed the chrono start button and it started to work again! It was then fine for a couple of days. Its now playing up again, keeps time for a while then stops, small shake for rotor to move and it sometimes starts again, sometimes winding it makes it start again

Has anybody any ideas or anything i can check? Just seems odd how it still sort of works so hoping its nothing to serious, if not might have to try and get it serviced. Many thanks for looking and all helpfull comments appreciated.

To me it really sounds like a dirty movement, or perhaps just a need for servicing. You would think that since it will run fine, that nothing is broken.
