Watches made from Bone and Wood

Found this amazing image of a pocket watch made entirely of Bone. The only things in the watch that aren't bone, are the metal springs. Apparently the Bronnikov family from Vjatka, Russia made these watches back in the 1800s. The watches today can command up to $25,000 at auction. Each watch was hand carved and painstakingly put together.

Here is the blog where I found the original story Watchismo
