استخدم الــ Timer هكذا :

import java.awt.BorderLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.text.DateFormat;
import java.util.Calendar;
import javax.swing.*;
import javax.swing.border.EtchedBorder;
import javax.swing.event.DocumentEvent;
import javax.swing.event.DocumentListener;

public class Montre extends JFrame implements ActionListener {

    private Timer minuteur = new Timer(1000, this);
    private JLabel horloge = new JLabel();
    private JPanel panneau = new JPanel();
    private Saisie heure;
    private Saisie minutes;
    private Calendar date = Calendar.getInstance();

    public Montre() {
        super("Horloge");
        setBounds(100, 100, 220, 100);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        horloge.setFont(new Font("Arial", Font.BOLD + Font.ITALIC, 32));
        horloge.setHorizontalAlignment(JLabel.CENTER);
        horloge.setBorder(new EtchedBorder());
        add(horloge);
        minuteur.start();
        panneau.add(new JLabel("Heure :"));
        panneau.add(heure = new Saisie("" + date.get(Calendar.HOUR_OF_DAY)));
        panneau.add(new JLabel("Minutes :"));
        panneau.add(minutes = new Saisie("" + date.get(Calendar.MINUTE)));
        add(panneau, BorderLayout.SOUTH);
        setResizable(false);
        setLocationRelativeTo(this);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        date.add(Calendar.SECOND, 1);
        horloge.setText(DateFormat.getTimeInstance(DateFormat.MEDIUM).format(date.getTime()));
    }

    private class Saisie extends JTextField implements DocumentListener {

        public Saisie(String libellé) {
            super(libellé, 3);
            setHorizontalAlignment(RIGHT);
            getDocument().addDocumentListener(this);
        }

        public void insertUpdate(DocumentEvent e) {
            changement();
        }

        public void removeUpdate(DocumentEvent e) {
            changement();
        }

        public void changedUpdate(DocumentEvent e) {
        }

        private void changement() {
            try {
                int h = Integer.parseInt(heure.getText().trim());
                int m = Integer.parseInt(minutes.getText().trim());
                date.set(Calendar.HOUR_OF_DAY, h);
                date.set(Calendar.MINUTE, m);
            } catch (NumberFormatException erreur) {
            }
        }
    }

    public static void main(String[] args) {
        new Montre();
    }
}
