Gains 10 minutes each day.

In 12 hours, there will be 11 overtakings.
That means 11 * 65 = 11 * 60 + 11 * 5 = 11 hours and 55 minutes
Thus, when the clock measures an interval of 12 hours, it actually is an interval of 11 hours and 55 minutes.

Thus the clock gains abt 5 minutes every 12 hours, or 10 minutes every day.

In a correct clock, The minute hand should overtake the hour hand in abt 65 minutes and 27.16 seconds.
