Antikythera mechanism

>The first commutator DC electric motor capable of turning machinery was invented by British scientist William Sturgeon in 1832.

There were some pretty cool automatic sawmills, power looms, wool machines, and agricultural machines. A horse/steam powered hay press or steam locomotives are surprisingly complex. But, I'll go with time keeping mechanisms & calculators. It isn't just that they are complex, but that the support system, tools, calculations, and methods required to create such precision mechanisms is what is most complex.
