IWC Big Pilot’s Watch Constant-Force Tourbillon Edition “Le Petit Prince”

At the Salon International de la Haute Horlogerie (SIHH) in Geneva, IWC Schaffhausen will be presenting two “Le Petit Prince” models and an “Antoine de Saint Exupéry” special edition in the Pilot’s Watches collection. The Big Pilot’s Watch Constant-Force Tourbillon Edition "Le Petit Prince" is the first pilot's watch from IWC with a constant-force tourbillon. For the first time, the Swiss watch manufacturer has used hard gold for the watch case – a significantly harder and more wear-resistant version of red gold. IWC has combined for the very first time a perpetual calendar with a chronograph function with the Pilot’s Watch Perpetual Calendar Chronograph Edition “Le Petit Prince”.​
