Watch \Watch\ (w[o^]ch), n. [OE. wacche, AS. w[ae]cce, fr.
wacian to wake; akin to D. wacht, waak, G. wacht, wache.
[root]134. See {Wake}, v. i. ]
1. The act of watching; forbearance of sleep; vigil; wakeful,
vigilant, or constantly observant attention; close
observation; guard; preservative or preventive vigilance;
formerly, a watching or guarding by night.

Shepherds keeping watch by night. --Milton.

All the long night their mournful watch they keep.
--Addison.

Note: Watch was formerly distinguished from ward, the former
signifying a watching or guarding by night, and the
latter a watching, guarding, or protecting by day
Hence, they were not unfrequently used together,
especially in the phrase to keep watch and ward, to
denote continuous and uninterrupted vigilance or
protection, or both watching and guarding. This
distinction is now rarely recognized, watch being used
to signify a watching or guarding both by night and by
day, and ward, which is now rarely used, having simply
the meaning of guard, or protection, without reference
to time.

Still, when she slept, he kept both watch and
ward. --Spenser.

Ward, guard, or custodia, is chiefly applied to
the daytime, in order to apprehend rioters, and
robbers on the highway . . . Watch, is properly
applicable to the night only, . . . and it begins
when ward ends, and ends when that begins.
--Blackstone.

2. One who watches, or those who watch; a watchman, or a body
of watchmen; a sentry; a guard.

3. The post or office of a watchman; also, the place where a
watchman is posted, or where a guard is kept.

He upbraids Iago, that he made him
Brave me upon the watch. --Shak.

4. The period of the night during which a person does duty as
a sentinel, or guard; the time from the placing of a
sentinel till his relief; hence, a division of the night.

I did stand my watch upon the hill. --Shak.

Might we but hear . . .
Or whistle from the lodge, or village cock
Count the night watches to his feathery dames.
--Milton.

5. A small timepiece, or chronometer, to be carried about the
