Not a RSC issue per se but when I returned my Tudor GMT to the AD that I bought it from (new) for the all too common date issue, I was informed that it was out of warranty by a month (it was 25 months since I’d bought it & several months since it has started playing up, but with Covid etc, I’d been unable to get to the AD to hand it in), I then had to explain that any Tudor bought between July 1st 2018 - Dec 31st 2019 have an 18 month warranty extension (effectively a 3.5 year warranty) - they didn't really give me the impression that they believed me but said ‘we will send it to Tudor for you and they may well look on your warranty claim favourably due to the recent pandemic’ etc.
I wasn't overly impressed tbh - hoping to collect the watch this weekend so will see if they've fixed it...
