Minute repeaters, the complication, came out of necessity for night policemen. At night, the town square would have its noisy clock turned off - since you don't want the clock to chime in the middle of the night affecting the citizens from sleeping. Policemen who had to be able to tell time in the dark generally had minute repeating pocket watches (wristwatches weren't popular yet). By the time the world transitioned to wristwatches in the 1930s - mainly because soldiers in WWI in trench warfare thought pocket watches were cumbersome - minute repeaters had become rare in wristwatches. Towns had electric lamps and gas lamps so most towns didn't need these expensive wristwatches. Towns without gas lamps nor electric lamps may have still employed the pocket watches for night policemen.
