I recently bought a Tag f1 Indy 500 from Watch33. Admitedly, it did take 3 weeks to arrive, having been imported from USA. However, after being assured ( by Anthony) that it would be dispatched on a certain date, I was able to track the watch on the FedEx site and followed it's progress from New York via Indianapollis, Gatwick, Carlisle then to my home address in Scotland. On arrival, my watch was well packaged with genuine Tag Heuer case and manual. There was no Tag warranty card with it but Watch33 did say in the advert that it is covered by their own guarantee. This is because they aren't registered Tag dealers. I have since taken the watch Watts watches of Switzerland in Edinburgh who confirmed it as the genuine article.
I'm very pleased with my purchase and saving of £250.
