In addition to telling time, the Christophe Claret 21 Blackjack (www.manufactureclaret.com) watch features a blackjack game played by pressing pushers on the side of the case. The wearer can also try his hand at dice, which are visible through a side aperture. Claret, who has created a host of unorthodox time pieces for other brands, perhaps best demonstrates his mechanical skills with the roulette game that is displayed on the reverse side of the watch. The game features a ceramic pointer that indicates the number and appears to bounce around just as a marble does on a real wheel. The 21 Blackjack, which has a starting price of $225,000, will have a very limited production run—21, of course.
