This is the Vintage 1945 Jackpot Tourbillon watch, made by esteemed Swiss watch makers Girard-Perregaux, and costing a cool $650,000 (about €444,000). What's so special about it? It contains a fully functioning slot machine and is entirely mechanically operated.

At the top of the face are 3 spinning reels, and when you pull the arm at the side (gold of course) each reel stops on one of 5 symbols giving 125 possible combinations. Attention to detail is exceptional down to the symbols on the reels which mimic those on the very first slot machine ever - the Liberty Bell.

With 501 moving parts, its a wonder of engineering and with an 18-karat rose gold finish, its understated looks are elegant rather than tacky.

In fact it's so complex, the second watch out of production will take another year.

To complete the package, the watch comes in a specially designed sleek black carrying case which opens to reveal curtains and the watch under LED lights, with cards and chips alongside. If ever a watch was to become a collectors piece, this is it.
