Kraken Watch is a division of LEPrecon which monitors 6 of the 7 Krakens which still exist. The watch consists of 100 Opal Koboi-class transmitters, which monitor the Krakens. If the transmitters reveal something wrong, an operative flies in such as in The Time Paradox, where Holly Short flew into Finland. The seventh Kraken was found when Artemis Fowl II shot it in The Time Paradox. Coded Radiation Tracers are also used to help locate the underwater boxes that monitor the Krakens' health.
