The NFC Chip works well, I always pay with my watch. The Strap fitts well. But, the leather already looses small parts around the thorn close, only after a few Days of wearing. It looks as it is years old already. Another bad issue is that the Strap came with only one small leather "thing" where it has to be push into after closing. On the pictures in the shop the Strap has two of them. I only recognized it now, when i was leaded to this review.
