A purpose-built tool for critical search and rescue situations, the Roadmaster Rescue Chronograph delivers extreme accuracy, easy readability and high functionality. Engineered with a patented pusher locking system, the chronograph function works in unison with the pulsometer scale to measure heart rate, while two illuminated sub-dial counters track elapsed time. The two chronograph pushers on the flank of the case employ a new patented locking system to eliminate any unintentional manipulation. The pushers are engaged or locked by being turned. The constant operation indicator at 9 oclock is also a re-engineering of the standard subsidiary seconds with greater visual impact. Atop the robust 41mm titanium-steel case of just 14. 8mm thickness, the steel bezel features a virtually scratchproof ceramic insert. To ensure perfect time reading even in total darkness, self-powered micro gas tubes are not only adorned on the dial and hands, an inset has also been added to the ceramic bezel. T
