Temerario is the most daring and innovative interpretation of Chrono 4 with a completely original and unique shape. This chronograph boasts 3 exclusive patents developed by Eberhard & Co. One of these regards the movement, another concerns the access system to the crown, and the third relates to the safety clasp of the leather strap and the bracelet. Equipped with a mechanical automatic movement and an Eberhard & Co. patented device, Temerario features the four counters in a vertical row.
