This website and business is pretending to be based in the UK. In fact is in Singapore. No problem unless there is a problem. You're unlikely to get a refund (I didn't) if there's an issue. The watch will take longer to get to you and you don't have the same consumer protection. Beware. You may lose money.
Amazon allows chinese sellers that flog terrible quality items. Once you've waited a month for an item to arrive, if you want to send it back, you'll have to pay for shipping to China. In my case the dodgy seller gave a fake UK address for a return. Amazon don't step in to take action. Instead the dodgy seller can get away with doing nothing. No refund, no action. Beware!
