Ukrainian watchmaker Valerii Danevych has figured out to make watches completely made of wood.
The only exception present in each timepiece is a metal spring, which helps it move.
Since 2005, Danevych’s birch watches can store up to twenty hours of reserve power, which is an impressive feat.
He was even able to make a necklace watch which was 1.3mm in diameter, using a microscope to help him with his work.
