It just boggles my mind that back in the 1840s such design technology could build a clock so high, with four 7 m diameter clock dials, and with around 2 seconds accuracy per day. To also know how to add or subtract a penny to the pendulum to adjust the accuracy, is also just a testament to the ingenuity of that age.
This video is one of the best explanations I've seen of how all the technology works together, in easy to understand animation.
