High torque clock movements become important when the dimension of the watch grows than 12-- 14 inches in diameter, since the min hands are big sufficient as well as thus heavy enough that common electric motors can't turn them. Clock movements without high torque completely take care of every little thing smaller, capturing a lot of the market. The inflection factor was picked to make sure that the conventional layout reduces thrown away power, offering a bulk of clients the lengthiest feasible battery life.
However high torque clock movements are however essential and very valued, since otherwise the bigger clocks would not work at all. Consequentially, these significant versions expend wattage at a quicker rate than normal ones, needing a modification of batteries a little bit extra regularly, or maybe making use of a C-cell battery as opposed to the common AA battery.
