For the first time, Jacob & Co. merged two typical Swiss traditions: a mechanical music box and a watch movement. This 18-piece limited series is brought to life by installing two music box cylinders and combs on a specially developed manual winding JCFM02 movement, which uses titanium alloy components for ideal sound transmission.
When the button at 2 o’clock is pressed, a 20-second melody will sound over 120 notes. In addition to bringing pleasure to the ears, it is also a visual feast, as the cylinder and blades rotate 120° around the dial during performance. At the same time, the three-axis tourbillon completes its rotation. In order to keep the 12 in the correct position on the off-center hour and minute dial, it can also be rotated counterclockwise, driven by a patented differential gear. Jacob & Co. Opera
