Quartz
As a pioneering company that always remains faithful to its philosophy of excellence, Patek Philippe was among the very first watchmakers to explore the potential of electronic timekeeping in 1948. It has every reason to be proud of its high-precision quartz movements whose plates, bridges and wheel trains comply with the same high quality standards that apply to its mechanical movements.
