This is a terrific watch. Beautiful and tough.

I’ve owned my Critical Mass Reactor for more than 10 years. The performance has been exceptional. These watches are gorilla proof. Wore out the original rubber band & replaced the battery twice. Thanks to the superlative factory refurbishment my watch still looks great in a dress or sports application. Reactors Customer Service is the best !! Highly recommend Reactor Watches.
