If this is like similar clocks I’ve seen, the pendulum is only esthetic and has almost no weight. The friction of the clock resting against the wall would be more than enough to counteract any forces the pendulum would exert. Two holes shouldn’t be necessary, but it will have to be pretty close to level for the tiny electromagnet to work.

Well, that seems like quibbling. Outside of legality, we’re talking 2 months.
But this reminds me of a joke.
A cop is doing his patrol on the night shift and notices a car parked at the local makeout spot a little before midnight. The interior lights are on and things seem pretty quiet. He pulls up and taps on the window. The driver rolls it down and asks how he can help. The officer sees a young man and woman sitting in the car, both reading a book. He asks if everything is okay and asks for ID. They both provide it. He notices the girl’s 18th birthday is tomorrow and the guy’s already an adult. He asks them what their plans are and the boy glances at his watch and says, “Well, for the next twelve minutes or so, we’re going to keep reading these books.”
