Skeletonizing is an age-old tradition in watchmaking. The challenge is to remove enough material from the movement to make it nearly transparent, without impacting its performance, precision, or robustness.
Jacob & Co.'s watchmakers have been skeletonizing movements for decades, so they understand exactly where and how much to remove, and the result is a nearly see-through movement, set up to maximize the beauty of this little engine on the wrist.
Underlying all this beauty lies the legendary timepiece workmanship for which Jacob & Co. is famous. The tourbillon was originally invented to be a single-axis, rotating cage secured from above as well as below to carry the regulating organ of a mechanical pocket watch for improved timekeeping performance. The version in the Brilliant Art Deco D-Flawless presents this more than 225-year-old invention in a yet more spectacular way.
The one-minute tourbillon features a delicately decorated cage that encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important components. This open-worked cage not only features an elaborate web-pattern in its architecture, but allows for an unobstructed and full view at the ultimate refinement of its detailing and operation. It is a constellation of superbly finished components that, when assembled and fine-tuned expertly, allows the JCAM05 movement to keep accurate time throughout its 72-hour power reserve.
The movement uses sapphire crystal plates to make the movement even more transparent, and the bridges of this spectacular movement are set with 177 multi-colored brilliant-cut fancy pink diamonds.
