The birth of Abraham-Louis Perrelet in Neuchatel, Switzerland heralded a new dawn for Swiss horology when he invented the automatic movement in 1777. 50 years later, his grandson Louis-Fr?d?ric Perrelet patented the split-second chronograph. To say the name Perrelet is synonymous to horological innovation would be an understatement. These timepieces are not mere time indicators. Watches such as the Perrelet Turbine represent centuries of technological innovation, astounding craftmanship, and design evolution. Clearly aviation inspired, the Perrelet Turbine with an approximate 40-hour power reserve features a double-rotor automatic movement with a turbine-styled dial. The concept is very well thought of as the singular face does not sacrifice legibility of its time and date functions. The Perrelet Turbine is available in two sizes of 44mm and 50mm and comes in gold or DLC treated steel or titanium.
