I bought a refurbished Apple Sport Watch 38mm for 200 dollars last week.  I have been pleasantly surprised how useful it is.  I love using it to send a quick reply to a text message with either a canned response or a dictated voice recognition text response.  I love the ability to quickly capture a dictated voice recognition note to Evernote.  I love the Do button app from IFTTT to quickly send things to different apps.  I have been finding new uses daily.  I am not sure it is worth full price but it is definitely worth 200 dollars.
