High torque clock movements end up being important when the size of the watch grows than 12-- 14 inches in diameter, since the minute hands are large enough and thus heavy enough that common electric motors can't turn them.
Clock movements without high torque completely handle whatever smaller sized, catching the majority of the marketplace. The inflection point was picked so that the traditional layout lessens lost power, providing a majority of clients the longest feasible battery life.
However high torque clock movements are nonetheless essential and highly valued, because otherwise the larger clocks would not function whatsoever. Consequentially, these hefty variations use up electrical power at a much faster price than average ones, needing an adjustment of batteries a little more frequently, or perhaps using a C-cell battery instead of the usual AA battery.
Electrical power is a step of electric work and also consists of voltage increased by current. For clocks, the voltage is set at 1.5 volts, the amount provided by the significant batteries. Hence, to achieve a particular level of torque, or work capability, requires a corresponding level of existing, translating essentially directly into battery lifespan.
