Laid-back face (4)
'face' is the definition.
(dial is a kind of face)
'laid-back' is the wordplay.
'back' says the letters should be written backwards.
'laid' back-to-front is 'DIAL'.
(Other definitions for dial that I've seen before include "feature of old phone?", "Select a telephone number", "Part of old telephone", "Watch face", "Calibrated face".)
