This $250,000 Girard-Perregaux Jackpot Tourbillon is one of the craziest expressions of luxury engineering ever created, with a fully mechanical slot machine hidden inside the watch case. Pull the lever and real gears engage, spinning three gold reels while tiny hammers strike a miniature gong to recreate the exact sound of an old casino slot, all powered by traditional watchmaking mechanics with zero electronics.
