I think the B-1 is a fantastic watch, and from what I've read, many many Breitling fans agree. If you look at the Breitling brand forum at TZ you will see most have one in their collection. I've heard that the B-1's replacement is considered a step back in beauty. I have handled the new one and I would agree, the dial is a little too flashy for me. If I had to guess, I would say the B-1 will be sought after by collecters as they become more and more scarce. I know I will be looking for one if I ever get plenty of extra cash around (I can dream). As far as if they will ever really appreciate in value, I really am not familiar enough with Breitling resale to say, but given what I have seen with it's popularity, it seems possible to me. If its that good a deal, and it is something you would enjoy owning and wearing, go for it!
