Found this handy document in my 1995 Fossil Collector's Club kit the other day. Forgot it was there and it's a nice listing of all the limited edition watches Fossil did from their first limited edition (SK 5038) in March 1992 up until LE 9457 Rodeo Watch done in December 1994. Anything after that we'll have to amend this as we go!
Amendment in 2012 - In our Facebook group is an ex-Fossil employee. He graciously helped us put together a new version of the limited edition check list below with many, many additions. Happy collecting!
