The Mondaine stop2go is a unique timepiece with its electronic switch in place of a conventional crown which serves as a function control for the model's specific movement for setting the time and resetting the sweeping seconds hand. To set the time on a Mondaine stop2go, you simply pull the switch out, turn it to the correct time, and push it back to its normal position.
In the event that the seconds hand is no longer stopping at the 12 o'clock mark, there is an easy solution for realigning the movement. Do not pull out the switch but rather push the switch inward for 3 seconds. Once the seconds hand stops after the 3 seconds, turn the switch until the seconds hand reaches the 12 o'clock position. With the seconds hand now stopped at the 12 o'clock mark, press the switch in once to confirm the reset.
Watch the video below to see how to set the time and reset the seconds hand on your Mondaine stop2go.
