In October 2012 for the first time ever a man broke the sound barrier outside a vehicle when he jumped from a balloon that was floating on the edge of outer space. That man, Felix Baumgartner, was the inspiration for Zenith in creating the Christophe Colomb Tribute watch. Wearing the El Primero Stratos Flyback during the jump, it paid homage to an amazing feat.
The most spectacular aspect of this watch is the self-regulating gyroscopic module. This is the first time for this type system to be used on a timepiece, and it basically holds the escapement in a horizontal position no matter which way the watch is placed. This might not seem critical, but it happens to bring perfection to this watch, allowing the balance wheel and the hairspring to remain horizontal consistently, which results in almost perfect regulation.
