Many pendulum clocks are capable of well under 1 ppm accuracy, which is better than many quartz oscillators. Here is a tour of clock precision by orders of magnitude:

Here is a world record setting pendulum clock from a few years ago:

Precision pendulum clocks are a very deep rabbit hole.

Shortt clocks achieved accuracy of around a second per year If my math is right, thats about 30ppb
