a nice solid watch
I've had this watch for a few weeks now and it appears to be a solidly built watch with a feel of accuracy and attention to details. I really like the the way it looks - bold but understated.
One improvement that I'd make is to make the hands more visible. Under certain conditions, usually interior lighting, they really blend in with the face forcing you to twist your wrist around until the right angle reveals the location of the hands. While you'll do better with a black face in this department, the silver face and black bezel, in my opinion, is still sharper in appearance.
As for authenticity, I compared the watch and its packaging (box, protective stickers) to that of the department store's and I feel confident about its origin. However, while I found all of the stickers to be intact, I noticed a few small strands of hair stuck on the inside of the band which indicated to me that the watch didn't come straight from Tag untouched. I decided to live with this as had I bought this from a department store, they'd likely have sold me a piece from the case tried on by numerous customers anyway.
