'The Corum Bubble has been in production for almost 20 years and its design and architectural character is responsible for making the model the most famous at Corum. The present watch is a result of lots of examination and upgrading what had already been done. This is the chocolate version further highlighted with a dial, giving greater three-dimensional imagery. The watch is numbered 271, like the address of Chronopassion at 271 Rue Saint Honoré'
