For 3 years now, Swiss luxury watch manufacturer IWC Schaffhausen has taken up the theme of the little prince in special editions. With these, IWC pays tribute to one of the bestselling books in literary history, written by legendary writer, pilot and adventurer Antoine de Saint-Exup¨¦ry. It all started in 2013, when the Big Pilot¡¯s Watch Perpetual Calendar Edition ¡°Le Petit Prince¡± (Ref. IW502802) and the Pilot¡¯s Watch Mark XVII Edition ¡°Le Petit Prince¡± (Ref. IW326506) were launched in honour of the world famous story¡¯s 70th anniversary. A unique example of the Big Pilot¡¯s Watch Perpetual Calendar Edition ¡°Le Petit Prince¡± (Ref. IW502801) in platinum was auctioned by Sotheby¡¯s in Geneva. The record sum of CHF 173,000 it raised went to the Fondation Antoine de Saint-Exup¨¦ry, which used it to further the humanitarian heritage of the Frenchman. The series of special limited editions of ¡°Le Petit Prince¡± continued in 2014 with the Pilot¡¯s Watch Chronograph Edition ¡°Le Petit Prince¡± (Ref. IW377706) and the Big Pilot¡¯s Watch Edition ¡°Le Petit Prince¡± (Ref. IW500908). In 2015, IWC Schaffhausen presented the Big Pilot¡¯s Watch Edition ¡°Le Petit Prince¡± (Ref. IW500909) in red gold in a limited edition of 250 watches. That same year, IWC Schaffhausen launched the new Pilot¡¯s Watch Double Chronograph Edition ¡°Le Petit Prince¡± (Ref. IW371807) with an innovative day display in the form of a circle comprising seven stars.
