Clock are my weekness… ;)
Some time ago I found funny clock on aliexpress. Try deal, I think and order this one. It was compelete kit, so easy to assemble. I gave a task to my old son to solder it. One hour later task was done. Really good work.
Btw, the clock is running accurately. No difference in a week.
