The Royal Collection is inspired by the timepieces created in the early part of John Arnold's life, and pay tribute to the watches he produced for King George III and members of the royal court. The timepieces in the Royal Collection demonstrate the brand's prowess in traditional watchmaking and classical decorative arts.
