"Ŝi trovis la horloĝon kiun li rompis."

Translation: She found the clock which he broke.

Is this correct? Should this be tiun instead of kiun?

Yes, "Ŝi trovis la horloĝon kiun li rompis" means "She found the clock which he broke". This "that" can be misleading but it's just another way of saying "which".
