They were designed by Louis Cartier and master watchmaker Maurice Couët, who at the time was only 18 years old. In 1911, he became the exclusive supplier to the Cartier house and was inspired directly by the celebrated conjurer Jean Eugène Robert-Houdin who was also an illusionist and manufacturer of automatons and watchmaker.

In 1912, Maurice Couet invented the very first mysterious pendulum, which he labelled model A. In 1920 he worked in collaboration with Cartier to develop the pendulum with a single central axis, unlike model A which had discs actuated by two axes located on each side of the base.

This single central axis allowed for great aesthetic innovations, such as the introduction of a central piece of citrine. The production of this ''mysterious'' pendulum model lasted about a year, making this piece incredibly rare.

The piece remained in the family, passing on to the hands of the Yturbe family, related to the collectors Carlos and Charles de Besteigui who had their Parisian hotels decorated by the Russian painter Alexander Serebriakov.

Presented in its original case and dating from the very beginning of the production line, this mysterious pendulum is today a rare testimony of the innovative spirit of the Cartier house and a tribute to France's master watchmakers.
