Purchased one of these synchronous motors which rotate at 6 RPM. (A synchronized motor synchronizes against the line current, which is kept at an accurate 60hz rate to allow its use to synchronize against time keeping devices.)

Built my first gear machine using my gear generation software.

This attaches to the synchronous motor using a specially designed 12 tooth 1mm pitch gear that attaches to the synchronous motor, and uses single-tooth counting gears to step down the rotation rate, so the last gear rotates at 1 revolution per day.

First attempt at designing a gear chain for a clock.

This helped me to resolve a number of bugs with the gear generation software, including bugs with the generation of certain gear shapes, and the generation of the STL files for the spacers that are used to hold the gears in place.
