The whole set is extremely well designed, with very tight tolerances and good machining. The interlocking mechanisms are ingenious. Details are already cut and ready to assemble. The laser cut wood is beautiful and smooth.
Fits together like a puzzle without glue or special tools.
If you assemble the product correctly and use the provided wax inside to reduce the friction between moving parts, the clock will run for 1-3 hours.
