A device in the setting of the game [[Counter:Side]], worn by humans who have become [i]Counters[/i].

It resembles an ordinary watch, but Counter watches function differently. The watch behaves more like the "Doomsday Clock":[https://en.wikipedia.org/wiki/Doomsday_Clock].
If the time "runs out", the Counter wearing the watch turns into a [i]Shadow[/i], the Counter-equivalent of a Corrupted Object (abbreviated as C.O. in-game).

To keep the watch from ticking down and raise the timer up, the counter must feed the device with a special rare element dubbed [i]Eternium[/i].
