Overview
A skeleton tourbillon under a diamond case
The Jacob & Co. Brilliant Tourbillon Art Deco, reference BT545.40.RD.AA.A, in an 18-carat rose gold case, 47 mm across and 14.35 mm high. The case is set with 237 brilliant-cut white diamonds, on a white alligator leather strap with an 18-carat rose gold clasp.
Jacob & Co. introduced the round Brilliant collection in 2017, with no lugs and the strap attached directly to the case. This Art Deco version takes its movement from Art Deco architecture: geometry, symmetry and clean lines. The pebble-shaped case has rounded edges, which Jacob & Co. gives as the source of the Brilliant name.
Hand-wound calibre JCAM05 is an open-worked skeleton movement built along strictly horizontal lines. It has 172 components, 19 jewels and a one-minute flying tourbillon. Jacob & Co. describes the movement as designed to match the case in its dual nature of jewellery and watchmaking. This version is limited to 18 pieces.
