The Rasputin Tourbillon is a watch of many secrets and concealed debauchery. To reveal its secrets, however, one must first break through a seemingly impenetrable fortress (the watch's case) that is composed entirely of baguette diamonds. The 47.6mm diameter case in 18-carat white gold is fully set with the lustrous stones, spanning from the case band and the bezel to the lugs and the crown. Jacob & Co. watch aficionados may recognize the slider that protrudes from the left-hand side of the case (also set with diamonds), which hints at just one of the timepiece's hidden features. Upon fully pressing the slider, the wearer is treated to an audible indication of the time, provided by the minute repeater function of the JCAM27 manually wound movement. However, when the slider is pressed only lightly, three baguette rubies set beneath it are revealed. After catching a glimpse of the baguette rubies, if the slider is released and pressed again fully, the true treasure of the timepiece is unearthed. The minute repeater chimes and the two swans in the upper half of the dial move. A sector that has been hand engraved with a motif resembling curtains then opens in the lower half of the dial to expose a hand-painted erotic scene that lies beneath. This articulated sector is one of the few components in the watch that is not composed of 18-carat gold and covered with diamonds. Height constraints required the featured material to be resistant, lightweight and as thin as possible, while still strong enough to support the hand engraving. Therefore, so a copper-beryllium alloy was used.
