Speaking of the chronograph, one of the words that is often heard is the "column wheel", which is a rotating cylindrical gear in the movement, which looks like a petal with 5 to 9 lobes. The function of the column wheel is to realize the transmission and disconnection of the timing power by the two different states of the engagement or separation with the clutch lever, thereby triggering the timing module to stop and stop the timing, and controlling the timing accuracy http://popularwatchesonline.blogspot.com/.
In the chronograph movement, the invention of the "column wheel" was earlier than the modern "leverage cam", but today it is not as widely used as the cam. Because the structure of the column wheel is more complicated, there are fewer brands with the column wheel technology, and the production itself is not much. In addition, many manufacturers do not have the ability to produce their own chronograph movements, and the purchased movements use lower cost cam technology. So we can think that the use of column wheel timing is a sign of fine watchmaking.
