This example is obviously acelerated for practical pourposes.
We have to conditions when using 24 hours system. 
The first one is reset unit hour when we reach Hex A and go one ten up.
The other one is to reset both hours counter when we reach 24.
Since unit hour reset is shared we need to use a XOR gate so we avoid a short circuit.

Good work. You can use only 3 logic gates too: 2 "AND" and 1 "OR" :)

Use AND when display Hex A and more one AND, in node C in top counter and in node B in bottom counter.
