Frequency: 21,600 vibrations/hour (3 Hz).
See-through case back, fastened with 4 screws.While modern barreled watches like Jean Dunand's Shabaka and the vintage rollers of the Patek Cobra incorporate timekeeping to this inventive display, the GP Jackpot represents what one-armed-bandits do best, taking lots of your money. When the arm on the side is pulled, the spin also activates a striking mechanism of chiming gongs - for those vintage casino sounds. Each roller has five symbols, hearts, diamonds, spades, horseshoes, and three liberty bells for jackpot. Just introduced this week at the Geneva SIHH show, this hautegadget has an actual miniaturized mechanical slot machine just above the hands and tourbillon. Well, since the Opus 5 concept watch ' Time Bandit' was never made, I guess I'll have to settle for this Girard Perregaux '1945 Jackpot Tourbillon'.
