Defined by its classical lines and timeless elegance, the Palatial collection combines restrained, yet powerful aesthetics with outstanding horological prowess. The fully exposed flying tourbillon, the exceptional finishing of all components inside and out and the mysteriously semi-translucent dial safeguard the Palatial Flying Tourbillon Hours & Minutes' position among ultra-high-end timepieces.

Whereas 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 Palatial Flying Tourbillon Hours & Minutes presents this 224-year-old invention in a yet more spectacular way.

The one-minute flying tourbillon of this Palatial model features a delicately decorated cage that encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important components. This openworked cage not only features elaborate, handcrafted decorations, but is only secured from underneath, allowing 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 194-component JCBM01 caliber to keep accurate time throughout its exceptionally long, 100-hour power reserve.

The case of the Palatial Flying Tourbillon Hours & Minutes measures 43 millimeters in diameter and just 12.70 millimeters thick between the top of its anti-reflective sapphire crystal and the lowest point of its case. Its case is crafted from 18K Rose Gold or Grade 5 Titanium and is finished with a combination of circular satinated, polished gadroon and high polished surface treatments, all executed to the highest possible standard.

The Palatial Flying Tourbillon Hours & Minutes is further characterized by the vivid colors and mysterious translucency of its dials. Available with semi-transparent blue, red or green mineral crystal dials, it curiously reveals the exceptionally finished dial-side components of its JCBM01 caliber, allowing for a closer look and appreciation of their functioning and execution. Hours and minutes are indicated by elaborately skeletonized hands.
