How to Accommodate Large Clock Hands
Huge clock hands are those that are longer than about seven inches (talking the minute hand, not the hr hand). The reason big clock hands are so marked is that sizes above that cutoff size consider too much for a conventional motor to turn. Simply put, the conventional torque is insufficient, needing the developer of the watch to buy a high-torque motion rather.
Big clock hands are in theory unrestricted in size, however virtually speaking you will not see any type of longer than eighteen inches, indicating that the corresponding clock would go to least a backyard in diameter. Also then, the likeliest application for such a timepiece would be something installed straight to the wall surface (making use of the wall as the dial, so to speak) without being enclosed in a situation.
