Pause to look at timer (9)
I believe the answer is:
stopwatch
'timer' is the definition.
(I know that stopwatch is a type of timer)
'pause to look at' is the wordplay.
'pause' becomes 'stop'.
'to look at' becomes 'watch' (I've seen this before).
'stop'+'watch'='STOPWATCH'
(Other definitions for stopwatch that I've seen before include "Timepiece for exact timing" , "Timing device, for sports perhaps" , "Timer for races, etc" , "instrument" , "Timepiece for recording speed of racers" .)
