As others have commented, I used RWR's service due to a lack of other options during the Covid-19 lockdown, in my case due to a battery replacement being required for my Tag Heuer watch. I was really impressed with how quickly the service was completed and how RWR kept me informed by e-mail every step of the way. I've had my watch back for a few days now and everything seems to be fine; the battery replacement came with a two year guarantee but time will tell on that count! The service was a little pricey (especially adding the cost of having to send the watch out using Special Delivery, though the return postage was paid for) but I'm hoping the quality and convenience will prove this worthwhile.
