For the world-famous poet and author of The Little Prince, Antoine de Saint-Exupry, poetry and technology, writing and flying were two sides of the same coin. Now the Big Pilots 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.
