The kanji 旧旧 is a phono-semantic compound (形声文字, けいせいもじ). The left side is a radical (偏, へん) representing "old" or "used." The right side is 臼 (kyuu), which originally depicted a mortar. The overall structure combines the sense of something used or old with the phonetic component to suggest an association with age and the passage of time. The right side's original meaning is now very different and doesn't affect the modern meaning of 旧旧 directly.
