The Moon Phase is a pocket watch belonging to Mamoru Chiba in the Sailor Moon manga, marked with a moon emblem. It behaves oddly, running backward once Usagi awakens as Princess Serenity, and becomes a small keepsake caught between the two of them.
A plain-looking pocket watch adorned with a moon crest, the Moon Phase is owned by Mamoru Chiba in the manga. Usagi comes across it after Mamoru rescues her from a fall, and at first it seems broken. Only when she awakens as Princess Serenity does its strange nature appear, as the watch is seen ticking in reverse.
The watch anchors a small exchange between the two leads. Usagi means to hand the Moon Phase back to Mamoru, while he intends to return a handkerchief she had dropped, but the plan falls apart when the Dark Kingdom abducts him. The item never surfaces in the 90s anime, though the Orgel fills a loosely similar space in the plot despite serving a different function.
Mamoru Chiba is the watch's owner, with Usagi holding it for a stretch of the manga. It later returns in the live-action series, but there Mamoru simply buys it for Usagi as a gift from a shop, and its part in the story shrinks even further than in the manga.
