On our broken watch, the Hour and Minute hands meet every 65 minutes, which in a 12 hour period is 715 minutes (65*11).
On standard analog clock, the second hand and the minute had will meet every 65.45454545 minutes based on the (12*60)/11 formula; which for a 12 hour period is 720 minutes (65.45454545 * 11 ~or using our previous formula~ 12*60).
720 - 715 = 5 minutes for 12 hour period
In a 12 hour period our broken watch gains 5 minutes and will not be the same again for a long time to come.
