In 2000, Corum released the Bubble - a whimsical and lighthearted timepiece created during the era of Severin Wunderman. Its most notable feature is the large sapphire crystal, resembling a bubble, which drew inspiration from the classic Rolex Deep Sea watch. After taking a break, the Bubble returned to the spotlight at the 2015 BaselWorld exhibition. As part of the Art-series, the L082/02996 model boasts a striking green python dial and strap.
