I believe the answer is:

digital

I'm a little stuck... Click here to teach me more about this clue!

'watch' is the definition.
(digital watch is a kind of watch)

I don't understand how the rest of the clue works.

(Other definitions for digital that I've seen before include "numerical information" , "Of data expressed as a series of 0 and 1" , "Like modern cameras" , "computerised?" , "Made up of numerals, a watch or other display" .)

I've seen this clue in The Globe and Mail.
