Overview
A skeleton movement made to carry gems
The Jacob & Co. Billionaire III, reference BL115.30.AC.UA.A30AC, in an 18-carat white gold case, 54 x 40 mm and 11 mm high. Case, inner ring, movement bridges and bracelet are set with natural, no-heat multicoloured sapphires and one white rose-cut diamond, on an 18-carat white gold bracelet with a folding clasp.
Jacob & Co. developed the movement of this watch to suit extensive gem-setting. Its bridges are thin and laid out in a geometric pattern that Jacob & Co. compares to the facets of a diamond. The skeleton calibre is hollowed out wherever a part allows it.
Hand-wound calibre JCAM39 was developed for the Billionaire collection. It has 167 components and a 72-hour power reserve. Jacob & Co. says its one-minute tourbillon is aligned vertically with a large barrel. This version is a pièce unique.
