Here is a short video to show how the stop seconds function works on the Aero CS. To set the watch against a known time source, simply pull the crown out. When the seconds hand reaches the 12 o’clock position, it will stop. You can then set the minute and hour hands as needed, push the crown in to start the watch, and you are set.
