Having owned both a GMT II and a Navitimer 01 LE which I still own, I would easily put it as the same quality as the Rolex. IMO, the dial work on the Navitimer 01 is better than the Rolex I owned. I've only owned a Navitimer 01(only Breitling I like) so I can't speak for the other Breitlings. I think Breitling as a brand gets bashed too much...mainly by snobs. Many of whom have never handled one!.
I understand their designs might not suit everyone but the quality is definitely there based on the one I own and the few I handled such as my cousins Unitime. This is coming from someone who had owned over 50 watches from Rolex to Breitling to more than a dozen Omegas etc!. Again, this is my opinion. Don't know much about movements but the B01 movement from what I have read and experienced is a good movement. Keeps excellent time. What I like is the 72 hour power reserve!.
