You might be too cool to wear a watch, but this wrist wizardry could make you reconsider that notion. The Louis Vuitton Tambour Mysterieuse Calibre LV115 watch appears to defy the laws of physics with its floating movement and suspended hour and minute indicators. How is this even possible?

The secret lies in two transparent sapphire disks supporting the hour and minute hands. Mysterieuse, indeed. The gold and steel masterpiece is completely mechanical, crafted of 115 hand-mounted parts, and runs for eight days on a winding.

Because the watch costs just over a quarter of a million dollars, Louis Vuitton lets you customize it however you want, and even includes a fancy trunk to store it when it's not adorning your wrist. Just be sure to hire an armed guard to accompany you when you wear such a precious thing.
