Year-old Rolex keeps stopping

[SusieB30]

I bought a new Rolex in August 2019, since when it’s been either worn or kept in a watch winder. Last time I had it out to wear was in July 2020, when it worked fine. Went to get it out of the winder today, and it wasn’t running. Wound it up, it went for about 30 minutes and stopped again. Same thing has happened about 10 times since, it never goes for longer than about an hour, and usually for a lot less. I’ve had a good few Rolex watches and have never had this problem before. Another watch kept under similar conditions is going fine, and even the ones that I keep in a safe and don’t wear often always wake up quite happily.

Obviously I’ve contacted the very exclusive watch shop who sold me the watch, but I’m not keen on having to pay for service and repair on what’s basically a brand new watch, so I hope they’ll agree to sort it out for free. Was just wondering if anyone had any ideas what the problem might be.
