One Man's Dream to Build a Better Watch. In 2003 Reactor Founder Jimmy Olmes set out on a mission to design a line of sport watches that would exceed the demands of the action sports athlete, while creating a style uniquely different from the norm. In short, he wanted to push well beyond what the watch industry had to offer and create a product that would truly set a new standard. Bold components, uncompromising quality and unconventional styling have combined to create REACTOR. REACTOR truly represents the best of what the world of watches has to offer.
