The Reactor Critical Mass is a more traditionally designed dive watch. With the unique shape of the case and an added unidirectional time bezel, it is a perfect combination of beauty and practicality. Reactor Critical Mass watches have solid 316L stainless steel construction, secure screw bar case-to-band interface, superluminova hands and dial markings, and a triple o-ring screw-down crown system, ensuring you a long-lasting, durable watch. Not only did Reactor build Critical Mass watches to be tough, but also function-packed. Date and day display, precise Japanese quartz movement and a shock-resistant movement holder add to the already feature-packed Reactor Critical Mass watches.
