The Monobloc Actuator is the latest innovation from Porsche Design. In this model, titanium, which has been  used successfully in engine construction for over 50 years, is given an entirely new form. In addition, the new watch model revolutionizes the traditional stopwatch function. In place of the familiar push-piece, the chronograph has a single rocker switch, drawing inspiration from  racing car engines. The innovative concept not only makes it very easy and precise to use but also increases the chronograph’s durability and lifetime significantly. Full Porsche performance – optimized for long distances. The technical appeal and surprising appearance of the single rocker switch, which is integrated into the   casing, give the Monobloc Actuator its unique character. Intelligent additional functions such as the two-zone mechanism make this sports chronograph the ideal companion at any 24-hour race. Design and function  at the highest level of performance.CASING: Diameter: 45.50 mm, Height: 15.60 mm, Material: Titanium, Finishing: Black titanium carbide coating, Crown: Screw-down, Glass: Sapphire crystal with hard coating, scratch-proof and with sevenfold anti-glare properties on both sides, Additional indication: 24-hour scale, Case back: Screw-down with tinted sapphire crystal, Chronograph actuation: Multiple-mounted rocker switch integrated into the casing, Water-resistant: Dynamically water-resistant up to 10 bar.
