The Big Pilot’s Watch Annual Calendar Edition “Le Petit Prince” Story

For the world-famous poet and author of “The Little Prince”, Antoine de Saint-Exupéry, poetry and technology, writing and flying were two sides of the same coin. Now the Big Pilot’s Watch Annual Calendar Edition “Le Petit Prince” brings these two worlds together. On the dial, the annual calendar shows the month, date and day in three separate windows. Its advance mechanism automatically takes the length of individual months into account and requires manual correction via the crown once a year at the end of February. The reverse side shows the little prince gazing at the sky with wonder in his eyes, standing on his tiny asteroid, which forms the rotor and revolves eccentrically around its axis. The in-house 52850 calibre has two barrels to provide the higher torque required to drive the three display discs of the annual calendar. In addition, when fully wound, the twin barrels supply enough energy for a full 7 days’ power reserve.

Petit Prince

Petit Prince

Antoine de Saint-Exupéry’s story “The Little Prince” has been translated into over 300 languages and is considered to be the most famous work written by the French flying pioneer and author. In the book, he tells of the journey of the little prince to seven planets, and of the inhabitants of these planets: the king, the vain man, the drunkard, the businessman, the lamplighter, the geographer and the rose to which the little prince returns after his odyssey. As part of the cooperation with the descendants of Antoine de Saint-Exupéry, IWC has been creating exclusive special edition Pilot’s Watch models as tributes to the wonderful story since 2013. These models all feature a trademark blue dial. For Saint-Exupéry, writing and flying were two sides of the same coin, which makes these special editions – the perfect symbiosis of poetry and technology – fitting tributes to his life and work.

Calibre Family 52000

The twin barrels are the trademark feature of the 52000-calibre family. They supply the watches with sufficient energy for a 7-day power reserve and drive energy-sapping complications like the annual calendar and perpetual calendar.

Annual calendar

The annual calendar is an attractive complication that shows the month, date and day in three separate windows on the dial. This complication automatically takes into account the differing lengths of individual months. It took 5 years to design.
