The clock looks like an ordinary grandfather clock, with carvings of Triceratops, Sauropods, Therapods, a Pterosaur, dinosaur footprints and ferns. It has a gold clock face and a creature dial that both glow blue when activated.
The clock activates right before the Museum's opening time in Andy's Dinosaur Adventures and after closing time in Andy's Prehistoric Adventures, signaled by its Pterosaur cuckoo and chimes. Andy asks the clock "To the time of [the creature whose era he wants to go to]", he then gets sucked in by blue light and the clock travels in time and space to the creatures time period and location then Andy is expelled from the clock.
After about 15 minutes in ADA and several hours in APA, the clock starts chiming again indicating it is about to leave. Andy then has moments to get back to the clock otherwise it will leave without him. When standing in front, Andy gets sucked back in by blue light and travels forward in time back to the National Museum, right before opening time, and Andy is expelled again.
Sometimes on Andy's and the Clock's time travel journeys, the Clock has been involved in some incidents:
- To be added...
- When the clock landed on an island in the Late Jurassic, Andy used the clock as a raft to get to the main shore, however Predator X knocked Andy off it. As Andy retrieved his backpack from the ocean floor, the clock washed up on the beach. (Kimmerosaurus and Clamshell)
- Once in the Late Cretaceous, a Hatzegopteryx pterosaur picked up the clock and flew off with it but dropped it in a pond with a crocodile in it. (Magyarosaurus and Reeds)
- The clock once landed on a ridge near a waterfall in the Great Rift Valley, Africa, Late Pliocene, meaning Andy was stuck. He then used the clock as a bridge to get to the other side but the clock fell into the river. It washed up on a rock downstream. (Australopithecus and Tool)
- The time travel visuals of the clock is from the time travelling scenes from the Walking with Dinosaurs episode New Blood.
- The Clock can be seen at the actual National Museum- https://www.nhm.ac.uk/events/andys-clock.html
