Not exactly useless. Wooden clocks used to be mass produced as an affordable option for the middle class.
Even though wooden clocks were once useful, this was not designed to accurately keep time but more to just be beautiful.
They were more accurate than people think.
If anyone comes across a wood movment, don't use oil on the pivots, and bushing (usually just a smooth hole in a piece of hardwood.).
Just dust, and use graphite.
