Ah, I didn't know Breitling made a tourbillon like that! When I scanned through pics on a google search, all I saw were cheap replicas with open hearts.:blush:
The bezel looks a bit different, but that could be a model variation, or even an option, as I see the Bentley line has several configurations possible.
The Mulliner Tourbillon is offered in platinum, yellow, rose, or white gold... so it could be in platinum or white gold. I can't see if the bar is straight or not, from those pictures. Guess it's still "up in the air" on authenticity.
