Inspired by the timepieces produced during the second part of John Arnold's life and later, by his son, John Roger, the constant search for absolute precision in horlogerie is clearly reflected in the Instrument Collection. Each and every timepiece is a complex navigation instrument on its own, with the difference between a timekeeping piece and a professional instrument being barely noticeable. One such impressive piece is the DTE Dual Time watch with its 18carat red gold case, one timekeeping dial being marked with Roman Numerals and the other with Arabic ones, a double tourbillon, 90 hours power reserve, fine circular graining and Cote de Genevre rayonnates finishes. The instrument collection is dedicated to truly pretentious horlogerie aficionados.
