In numbers

Bob has wound the clock around 1,564 times over the past 30 years.

He has clawed back around 26 hours from the clock, which gains a minute a week.

He has turned the internal clock and bell mechanisms almost 220,000 times.

In the process he has climbed up and down 172,000 steps.

It takes Bob around an hour to leave his home, complete the weekly clock winding process and return.
