Crossword Genius

Observe item with a strap (5)

Ross

I believe the answer is:

watch

I believe this clue is a double definition.

'observe' is the first definition.
(I know that observe can be written as watch)

'item with a strap' is the second definition.
(eg a wrist watch has a strap)

(Other definitions for watch that I've seen before include "period of duty" , "Observe - timepiece" , "Observe - guard" , "Keep under observation" , "Timepiece - look out" .)

I've seen this clue in The Times.
