Overview

Two flying tourbillons under a diamond dial

The Jacob & Co. Billionaire Double Tourbillon, reference BL140.30.BD.AA.A30BD, in an 18-carat white gold case, 54 x 40 mm and 11 mm high. Its 18-carat white gold dial is set with 169 emerald-cut white diamonds (≈11.12 ct), on a black alligator leather strap with an 18-carat white gold deployment buckle set with 30 emerald-cut white diamonds (≈13.50 ct).

The skeleton movement is kept out of sight. A dial set with diamonds in a brick-wall pattern covers it, with two round openings that show the tourbillons. Jacob & Co. describes it as the first Billionaire with a full dial.

Hand-wound calibre JCAM50 has two barrels, each connected to a flying tourbillon. The two tourbillons work together, and a differential system combines their timekeeping to drive the hour and minute hands. This version is limited to 18 pieces.
