Why is the stopwatch made on the handler in android behind?

Question

Android

Made a stopwatch. The basis of his handler. The algorithm is like this.
handler.post(new Runnable(){
public void run(){
second++
//here I update the view by inserting the second variable into it
handler.postDelayed(this, 1000);
}
});
Essence of the question. As long as the interval is 1000 milliseconds, everything is fine. As soon as I do less than 500, the stopwatch starts to lag behind. At what on 100 milliseconds lags behind 1 second per minute. Broke my whole head. How to make accuracy normal? And if it is not possible to do this on the handler, what can be used instead?
