The Circus Watch is a 'monster drop' that was introduced during the Nightmare Boss Update, an extension of the Ratboy's Nightmare Update. It is one of the many collectibles that are needed by the players in order to complete the entries of the Itempedia of the Nightmare. The Circus Watch can be obtained as a possible reward from the Ratboy's Nightmare Dungeon.
In appearance, the Circus Watch is nothing more than a simple brass pocket watch with a brass chain attachment. Other than that, not much can be said about its overall looks.
Similar to the Skip Tickets' functionalities, the Circus Watch will be activated to bring the player(s) straight to the 'Circus' phase of the Ratboy's Nightmare dungeon, effectively skipping previous instances needed to defeat the boss of the Nightmare.
- Unlike most collectibles of the Nightmare, the Circus Watch are stackable, enabling players to bring in a large stack of Circus Watches whenever they want to do a dungeon session in Ratboy's Nightmare.
- It is one of the two items to receive a black-purplish hue as its outline. The other item to receive this 'special' outline is the Honoring Blade.
