A masterwork of watchmaking, skeletonisation, and jewellery, this watch is an impressive 48mm in diameter but incredibly thin, with its elegant profile matched only by the barely-there movement. Despite having been open-worked to an astonishing degree, the calibre 17’’’170 inside has been richly hand-engraved with an elaborate motif that continues into the front and back of the case, including the bow. The case of the watch is set further set with diamonds on its front and back bezels, as well as the bow. A dozen rubies sit around the front bezel as hour markers, accentuated by a large ruby cabochon inlaid into the crown.

Most unusually, the case band set with an uninterrupted procession of pearls. Two crucial details set this particular watch apart from others like it, rendering it most probably a unique creation: Firstly, this example is fitted with has crimson hands that match the rubies perfectly, in contrast to the usual black hands fitted on other examples. The red hands are exactly the size, shape, length, and profile as the black hands found on the standard models, and are likely a custom order.

The other unique characteristic of the watch is the diamond setting. A similar example that sold at auction in 2006, with a movement number just one digit away, was set with 244 diamonds totalling 1.87 carats. This watch, in contrast, is set with 177 diamonds of 1.71 carats, signifying that the stones on this watch are likely larger in size.
