Example of Complicated Systems Star Caliber Patek Phillipe mechanical watch. We understand: how it is constructed, the required tolerances, the order of assembly. Each component works in unison to accomplish a global function: keep time precisely. We can take a reductionist path to define the smallest required parts and can further write equations of motion to predict the performance and functionality of the watch.
