With the new MONOBLOC ACTUATOR Collection, Porsche Design sets new standards in the art and science of time measurement. The role model for this innovative mechanism is the racing engine of the new Porsche 911 RSR: a paradigmatic example of precision and performance on the highest level. The MONOBLOC ACTUATOR GMT-Chronotimer All Titanium comes in a 45.5 millimeter titanium case and achieves the unprecedented feat of literally engineering the chronograph’s buttons seamlessly into the case of the watch. A multiply borne rocker switch alternately sets into motion and halts the chronograph mechanism of automatic Calibre ETA Valjoux 7754. Like the valves in the racing engine of the 911 RSR, this mechanism provides absolute precision, dependability, and continual, reliable protection against moisture penetration throughout operation. This means the stopwatch function of this chronograph, which is pressure-resistant to ten bar, is operational underwater.
