Clock in Chinese / Japanese...

剱 is the modern Japanese way to write sword.

This Kanji character comes from original Chinese. This form would also be understood in Chinese (there are often several ways to write the same character) but I suggest this one only if your audience is Japanese (because they've settled on a slightly different form as the standard in China).

In Japanese, this character also means saber/sabre, blade, bayonet, stinger, and clock hand (clock hands are the “swords” of the clock).

The meaning of 復古 can vary depending on the context. It used to mean a return to the old ways.

It can also mean “to turn back the clock,” “retro” (fashion style based on nostalgia, esp. for the 1960s), “revival,” or “restoration.”

The return to “the old ways” was also an aspiration of Confucius about 2500 years ago. This proves that “going retro” or “old school” has been cool since at least 500 B.C.

千慮一得 means “1000 tries, one success,” or “[a] thousand tries [leads to] one success.”

This proverb is a humble way to express your success, ideas, or accomplishments. As if you are a fool who just got lucky in inventing or creating something.

Translations for this proverb include:
Even without any notable ability on my part, I may still get it right sometimes by good luck.
Even a fool may sometimes come up with a good idea.

Compare this to the English idiom, “Even a broken clock is right twice a day.”
