Billed one with German antique clock (9)
I believe the answer is:
goldeneye
'billed one' is the definition.
(type of duck, animal with a bill)
'with german antique clock' is the wordplay.
'with' means one lot of letters go next to another.
'german' becomes 'g' (abbreviation).
'antique' becomes 'olden'.
'clock' becomes 'eye' (both can mean to see).
'g'+'olden' is 'golden'.
'golden'+'eye'='GOLDENEYE'
(Other definitions for goldeneye that I've seen before include "Northern diving duck - 1995 Bond film" , "spy film" .)
