i have the option to purchase a 5722 at what appears to be a very favourable price. However there is always in the back of my mind some self doubt as to whether the watch will stack up long term as a reasonable investment given the size of the outlay and wondered if anyone out there has any views on this particular piece. I appreciate its not all about the investment but if the sky fell in one day it would be nice to know i wouldn't take a bath on it either.
