Guys just be aware! You've been warned! I ordered a rather expensive (for replica) watch from this site. Apart from the fact that it came from China, NOT from the UK... it didn't take 5-8 days to arrive but... 18 loooong days!
The watch (a Rolex Sea Dweller) looks pretty authentic. However, on the description states that it's water resistant to 100m and that the HE valve is functioning too...!
When I asked them whether I can take it diving with me, they replied NO, but that I could wear it in showering, surface swimming, wash hands and the like.
I put it under the tap the other day and it passed its first test successfully. Certainly I wouldn't take it to diving even if they'd claim so.
I also asked them whether the 1 year warranty would cover it, if I took it swimming and found that it's not that water resistant...! They replied that it would be covered by the warranty. It's some consolation afterall. Take care all.
