aP DoWatch "Everyone"?
hehehe
You could make a script, now that I think about it...
Make 4 game logics, named "North1", "South1", "East1", and "West1"
Then...in your script, make a loop...
#loop
<nameofunit> DoWatch (getpos North1)
~10
<nameofunit> DoWatch (getpos East1)
~10
<nameofunit> DoWatch (getpos South1)
~10
<nameofunit> DoWatch (getpos West1)
? (StopWatchin) : exit
goto "loop"
This will make your unit spin about in the space of 40 seconds. Combine this with your binocular command, and he'll scan the horizon in a clockwise manner. Alternatively, if you wanted to just have him watch a certain "cone" of the horizon, just make two game logics and place them where the edge of the cone lies. He'll look between the two points, going back and forth. Try messing around with the delay I put there ("~10") until it suits your needs.
Also, I put that IF statement there at the bottom of the script so if you wanted him to stop looking around (such as when he sees an enemy), just set StopWatchin to true.
