John Reardon first became interested in clocks and watches while interning at the American Watch and Clock Museum in his hometown of Bristol, Connecticut. While completing a degree in history and languages, he worked as a curatorial assistant at the Willard House and Clock Museum in Grafton, Massachusetts. His passion for all things horological brought him to Sotheby’s New York where he became a noted expert in watches and clocks. In 2001, he joined the Henri Stern Watch Agency (Patek Philippe USA). Most recently, he rejoined Sotheby's Watches as Head of the Department and International Senior Specialist.
