Function
The functions of a single push-piece chronograph are activated via the
crown only. To start the chronograph, press the crown once. When
you press the crown again, timing will stop and you will be able to read
the elapsed time. To reset the chronograph, press the crown again.
Important! Unlike a regular chronograph, once stopped, timing can
no longer be restarted / continued. Simple timing is the only option.
