This pocket watch is an item of Levi own invention, using both his skill for music box craftmanship and clock making. Jack made it so that a melody that Celia had composed, named Lacie, would play whenever the watch opened. While Celia composed the song, her twin sister, Lacie , had added lyrics to the tune, making the melody embody herself.
Jack had crafted the pocketwatch as a reminder of his beloved Lacie , who was taken away from him when he was eleven. Whenever the watch is opened, it plays the sad tune with a light undertone that Lacie always used to sing.
