I have owned 2 TT Subs. Neither were very convincing so I traded them. But this Navitimer two-tone was much more convincing. Perhaps because the watch was really heavy (due to 7750) and the bracelet felt sturdy.
Gold plating was very well done, and I couldn't have told it was a rep (if I wasn't such a hardcore watch nutcase).
I understand Breitling isn't for everyone, but it was surprisingly well done. So two-tone reps CAN be good. Plated reps of full gold watches are completely different matter.
