It makes collecting other brands difficult as I always see a Breguet I would rather have. I would love to own a 7787 but my wife thinks I should get the Lange1. I will decide by the end of the year but the Breguet aesthetic evokes emotions in me that no other watch brand can. With ALS it is more of an intellectual appeal.
613 Breguet listings are live on the eBay market and 169 collector listings on the WatchProSite marketplace.
