Since 1839, Patek Philippe has been designing and manufacturing timepieces synonymous with reliability, accuracy and precision. In the late 17th and 18th century, pendulum clocks known as regulators, illustrious for their precision, served as reference timers in a watchmaker’s workshop. The new rose gold reference 5235 Annual Calendar Regulator pays tribute to the early regulator clocks. #PatekTime #PatekRegulator
