Watch perhaps for American magazine article (9)
I believe the answer is:
timepiece
'watch perhaps' is the definition.
(watch is a type of timepiece)
'american magazine article' is the wordplay.
'american magazine' becomes 'Time'.
'article' becomes 'piece' (piece is a kind of article).
'time'+'piece'='TIMEPIECE'
'for' acts as a link.
(Other definitions for timepiece that I've seen before include "alarm, perhaps" , "Watch, say" , "non-striker?" , "Clock, for example" , "Chronometer" .)
