The center of mass including the nuts and bolts occurs 0.07 m from the rotation point with a total mass of 72 g. Using the period equation for a simple harmonic motion, the period ends up being 0.531 seconds.
Include a diagram, equations and the numerical analysis to predict what the oscillation frequency or oscillation time is of your clock based on inertial analysis.
Based on the simulation graph, the oscillation time is 0.65 seconds since that is the x-distance between two concurrent peaks.
