How it's used
Originally derived from the gambling world where someone would monitor the surroundings for police raids, this term is now used for any situation requiring a lookout. It implies a sense of secrecy or illicit activity, even if the context is just a harmless prank or a minor rule-breaking event. It is rarely used in professional or formal security contexts.
Examples
You keep watch for me while I go in to get my stuff back.
Who was supposed to be keeping watch earlier? How come you didn't know someone was coming?

Common phrases
to be in charge of keeping watch
Common mistake
Do not use this to describe a lifeguard or a security guard, as those roles are legitimate and public. Using 睇水 implies the activity being watched is something that should not be seen by others.
