Clock part found in an op shop (6,4)
I believe the answer is:
second hand
'clock part' is the definition.
'second hand' can be an answer for 'part' (I have seen 'part of watch' mean 'second hand' so perhaps 'part' could also mean 'second hand'). I am not sure about the 'clock' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for second hand that I've seen before include "Watch component" , "Not new - part of watch!" , "going quickly on the clock?" , "Part of a timepiece" , "Pointer on dial" .)
