First, congratulations for conceiving of a clock which ceases to function during the dark hours, therefore about half of the day in an average season. The makers of ancient sundials would like a word.

Second, you've indeed created a novel interpretation of "still working... without adjust... still running" for such a lousy timepiece.

If you choose to write those claims without qualification, then indeed I would say you epitomize the cliché that "even a stopped clock is correct twice a day."
