In 2017, Jacob & Co. created a new ladies’ collection that looked like no other. Round, without lugs, with a strap directly attached to the case, Brilliant was designed to be versatile, precious and to embrace the entire range of gems Jacob & Co. loves. Brilliant Mystery is the ultimate evolution of Brilliant in creativity, gem-setting and technique. Brilliant Mystery is a tribute to one of the greatest achievements of high watchmaking : Mystery Clocks. First invented by 19th century watchmaker and illusionist Jean-Eugène Robert-Houdin, they amazed the crowds with their intriguing and apparently impossible mechanisms. An island sits in the middle of the ring-shaped case, with two floating black triangles telling the time. Instant puzzling follows the amazement created by the all-around gem-setting. Brilliant Mystery is entirely covered in gems, from central island to case. Jacob & Co. exclusively selected the baguette cut. In order to recreate the smoothest surface, Jacob & Co. only works with the invisible setting technique. No prongs, no metal appears that would break the continuous array of gems. White diamonds. Emeralds. Rubies. Sapphires. Tsavorites. Rainbow color arrangements. Brilliant Mystery is Jacob & Co.’s ultimate expression of playfulness and gem-setting.
