From what I have read these were given away if you made a $29,000 donation to the charity and although there were only 50 made there seem to be a lot of them on the secondary market at even less than the initial donation asked.
I am not surprised, although the watch is very nice 48mm cannot be worn by many. The Jules Audemars Chronograph from the late 90's with a similar case and 39mm probably had much more success
