Clock occasionally found in Sweden (3)

I believe the answer is:

see

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

'clock' is the definition.
(clock can mean to see or realise)

'occasionally found in sweden' is the wordplay.
I cannot really understand how this works, but
'sweden' could be 's' and 's' is located in the answer.
The remaining letters 'ee' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for see that I've seen before include "Perceive with eyes or mind" , "Visualise" , "Three points" , "Witness; ensure" , "responsibility of a bishop" .)
