The Christophe Claret Blackjack 21 has three casino games built-in to the movement. The first game, Blackjack, takes place on the dial and is controlled via pushers. The cards shuffle behind the transparent smoked dial and appear through apertures when cards are dealt. The second game, dice, is on the side of the case in a clear compartment that has mini dice, allowing you to basically shake the watch and play dice on your wrist. The third game is roulette, just flip the watch over and the rotor acts as a working roulette wheel. $170,000. via
