A blue sphere occupies the left-hand portion of the case, magnificently showcased by a sapphire crystal with a small dome, attracting everyone’s attention. It features twelve engraved numerals and rotates on itself through three rotation axes to reveal the current hour. This hypnotic dance, which initially appears totally random, actually follows a strict choreography, dictated by four conical gears that move around two crossed spindles inclined at an angle of 21 degrees. Two polished titanium cases featuring a blue PVD treatment adorn this conical differential to create a yin and yang watchmaking composition that forms a sphere.
To the right of the sphere is a retrograde minute display with a hand that travels along a fine and elegant minute track that opens onto the movement and partly reveals the balance. This aperture brings the gear train into view, which slows down the course of the minute hand when it returns to zero, regulating its speed so as to reduce impact forces. The differential and snail used to trigger the jumping hour can also be seen beneath the minute hand. The minute track and the applied silvered diamond-polished minute numerals are fixed to an intermediary sapphire crystal dial with a smoked metallic finish that adds to the piece’s transparency.
