So, I've posted recently about a nice wooden wrist watch. In the more distant past I've also posted about a pocket watch with a wooden mechanism. Taking this to the next logical step, here is a wrist watch with wooden wooden works. That's right, those tiny pivots, pinions, wheels, levers, and balance wheel are all made of wood. The only non-wood part are the metal springs needed to power the movement and cause the balance wheel to oscillate. Many of the parts are made from birch and other woods such as juniper and bamboo. Some of these watches will run for a full day and and are accurate to withing five minutes a day.
These remarkable creations are the work of Valerii Danevych -- a talented Ukrainian man with no formal watchmaking experience. Granted, this achievement required a certain genius, but it should still make each us question if that the limits we place on ourselves exist only in our minds.
Here is where you can see the full article, titled Carpenter carves functioning watches entirely from wood.
