Sorry, Monkey zodiac animals come and go, but only a few creatures make for perennial motifs in the horological ecosystem. Sleek, beautiful and dangerous, the snake has long been a top choice for adorning timepieces, and Ulysse Nardin harnesses these qualities in one of its latest designs. The glamorous evolution of a watch first unveiled in 2014, the Royal Python Skeleton Tourbillon features a beautifully detailed hand-painted snakeskin finish on its bridges.

Coupled with a python strap, the snake-centric touches add an organic edge to a skeleton watch that, on its own, stands out with its architectural, avant-garde construction, as well as features like its silicon escapement components. The watch retails for $126,500 and is available in a limited edition of 18 pieces.
