Sebastian Packer, a London-based clockmaker, has spent 30 years searching for a specific antique known as the Judas Clock. This Italian-made clock operates only when the 30 silver coins paid to Judas Iscariot are placed in its weights. Legend holds that the clock brings violent death to its owners. Sebastian's obsession stems from a traumatic event in his youth: at 14, he witnessed his father's death, which he attributes to the clock's curse.
