Help please GMT-II perpetual not working

[funkyr]

Hi all,

A few days ago the perpetual function on my GMT-II stopped working. 116710LN

I usually wear the watch daily for 8 hours.

For about 4 days when I don't wear the watch for 4-5 hours (ie overnight) it stops completely. I've tried manually winding it up all the way and the same thing still happens.

Interestingly when I shake the wactch when it's discharged it ticks along so that tells me the perpetual winding thing works but maybe the spring that charges it is faulty?

Unfortunately out of 2 year warranty I've owned the watch for 2.5 years now.

Any suggestions would be welcomed thanks!
