In 2000, Corum released the Bubble watch - a playful and fun timepiece created during the late Severin Wunderman's reign. The watch's standout feature is its oversized bubble-shaped sapphire crystal, reportedly inspired by the Rolex Deep Sea. After a brief hiatus, the Bubble made a comeback at BaselWorld 2015. At the 2016 show, the L082/02999 Bubble Game Casino Chip was unveiled. Its dial mimics a $100,000 casino chip and the time is told by the iconic feuille hands.
