Not superb! It does function right!!! Omkarsing did not consider the typical problem on the two different cycles a 12 h clock comes up with. The first cycle goes up to ten. The second cycle goes up to two 2 PLUS the next turn starts with one and not with zero zero!!! This circuit does the first cycle right. But on the second cycle it goes up to 11 only. That's wrong! Then it starts with zero zero the next cycle...that's wrong too. Although this clock is badly made it shows the right time except 2 hours around noon and 2 hours around midnight. This clock has to be modified with logic gates for the second H display. See solution on my page.
