Paradive Type I Class B

The TR-50717 (“Paradive, Class B”) is Tornek-Rayville’s evolution of the military watch specification MIL-W-50717. After a survey of end users, we identified issues and weak points with the first generation contract watches and re-engineered the design to enhance and extend performance in challenging environments. The monocoque case of the first Class As and Bs minimized the number of water ingress points, but in practice the design was challenging to service and crystals developed stress fractures over time rendering them illegible. The two-piece stem the construction required was another vulnerability, usually revealed when the crown came off in one’s hand while hack setting the time.
