Where can I buy a complete Apple Watch display assembly?

If you search on eBay for Apple Watch Assembly you can find some fairly easily. They tend to all come from China so in the UK it takes about 3-4wks to arrive. But the quality is very high and I can attest to that having used them a few times now. They're about £135 each at the moment incl delivery. You may or may not get a seperate vat bill through from customs. Depends on wether they've already met their quota ;)
