Hi

Consider that the clock in question *could* be one of these:

http://www.simonsdialogs.com/2016/09/a-precision-pendulum-clock-and-an-even-more-precise-time-interval-counter/ <http://www.simonsdialogs.com/2016/09/a-precision-pendulum-clock-and-an-even-more-precise-time-interval-counter/>

They are quite a step up from what most of us think of when a pendulum clock is discussed. Still 
something that “grandfather” might have owned and used for years and years. There are even 
better versions out there. Running the vacuum pumps on them gets a bit noisy though ….
