Magazine article that could be a wind-up (9)
I believe the answer is:
timepiece
'that could be a wind-up' is the definition.
'magazine article' is the wordplay.
'magazine' becomes 'time' (US magazine).
'article' becomes 'piece' (piece is a kind of article**).
'time'+'piece'='TIMEPIECE'
(Other definitions for timepiece that I've seen before include "Maybe hunter" , "Chronometer" , "non-striker?" , "Maybe watch" , "Watch, say" .)
