The clock is finished! I could barely be any happier with how it has turned out. I’m even pleased with the wood work.
The only exposed materials are wood and glass (excusing the wire out the back) and so far it hasn’t lost any accuracy, and it’s been running for 3 days.
Initially I did have some issues with it skipping time when touched but I traced that back to a loosely connected chip.
Time for a new project!
