Hi, I've owned a bb58 for 8 months and last night I noticed it stopped running on my winder (never happened before). In addition:
1. I tried to manually wind the watch but after 20 turns the watch was still dead. The winding feeling was also very different: it used to be smooth but it felt bumpy (it's like when you've reached maximum power reserve and it stopped you from overwinding).
2. I then gave the watch some shaking, this time the second hand started to move for about 5 seconds then stopped again.
I've been wearing this watch in rotation with others and I'm always careful with it (never dropped). Since I'm working at home recently the watch was on the winder for the most of the time (a Rapport London winder).
I'm in contact with the AD but not sure at this peculiar moment if Rolex/Tudor service centre is still open.
