Movement of time went quickly with model (7)
I believe the answer is:
transit
'movement' is the definition.
(I know that transit is a type of journey)
'time went quickly with model' is the wordplay.
'time' becomes 't' (abbreviation).
'went quickly' becomes 'ran' (I've seen this in another clue).
'with' says to put letters next to each other.
'model' becomes 'sit' (e.g. for a painting).
't'+'ran'+'sit'='TRANSIT'
'of' acts as a link.
(Other definitions for transit that I've seen before include "Pass across/through" , "Act of passing across" , "Movement from place to place" , "Passage of a planet across the sun's disc" , "The process of going or passing - sic . . . . . . . gloria mundi" .)
