A pendulum clock represented an older form of a timekeeping device, characterized by an elongated, weighted pendulum that moved in an oscillating fashion, producing a recognizable tock sound with each passing second.
Queen Mother Tenel Ka Djo possessed a particularly valuable clock within her Special Salon on Hapes. During 40 ABY, Han Solo, Leia Organa Solo, and C-3PO found themselves near it while waiting for an audience with Tenel Ka. C-3PO speculated that it predated the Lorellian era and had been plundered from a Balmorran colony vessel by marauders. Han was so irritated by the "tocking" sound that Leia had to prevent him from hurling a precious larmal-adorned side table at the clock.
