Poor Mr. Clock, he is always at risk of being hammered or damaged in so many different ways, just because he is doing his job every morning.
Extremely useful but utterly hated at the same time, he is facing the same routine every single day.
Right after announcing that it is 7 a.m. he has to run for it, because Hammer's only desire is to see him smashed.
It is very likely that the previous clock ended under the fury of Hammer, which is probably why he got the job in the first place.
And, apparently, he is not willing to quit just yet, having one more clock to take care of.
