Tips on how to set the time on a watch.
In most watch movements there are small gaps between the teeth of the gears.
The direction of their last motion will determine if the gears have a gap to fill before they push the next gear along.
When setting the time; if the last motion made is moving the hands clockwise, then a gear like this Third wheel will need to move forward and a few seconds before it engages with the driving wheel.
So for the second hand not to get ahead of the minute hand, the hands should be set by having them move anti-clockwise in the last motion.
