Watches that can be read backwards (4)
I believe the answer is:
sees
'watches' is the definition.
(seeing is a kind of watching)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sees that I've seen before include "Observes the bishops' domains" , "Clocks" , "Gets sight of" , "Dioceses; views" , "Spots" .)
