• I understand most watch faces do something like

    setInterval(drawSeconds, 1E3);

    to show the seconds and there is a queueDraw in some.

    I still don't get how to syncronize seconds and minutes - and using setInterval is a bit laggy.
    When I set the interval to 1 second it will be executed sometime between the beginning and ending of the second. How can I execute just at the beginning of the second of the internal clock? Is there some kind of trigger for that?
