With an oversized case and huge domed crystal, the Bubble introduced in 2000 by Corum was the brainchild of Severin Wunderman. Among the first Bubble watches to make their debut was a watch with a stylized skull on the dial. Wunderman was obsessed with life, death and the concept of Dia de Muertos, a celebration where friends and family gather to honor the dead in a festive manner. Now, Corum is launching the new Bubble with the new Skull X-Ray watch, inspired by early designs.
