Contemplated minute and second hand (5)
I believe the answer is:
mused
'contemplated' is the definition.
('muse' can be a synonym of 'contemplate')
'minute and second hand' is the wordplay.
'minute' becomes 'm' (abbreviation).
'and' means one lot of letters go next to another.
'second hand' becomes 'used' (I've seen this before).
'm'+'used'='MUSED'
(Other definitions for mused that I've seen before include "Reflected or pondered" , "Thought (to oneself)" , "'Meditated, mulled (5)'" , "Reflected in silence" , "Was absorbed in thought" .)
