After releasing a teaser music video for "Time Machine", now Girls' Generation launched a full version of the clip. The music video full version is made different from the previous teaser. If the teaser comedy actors they involve Japan, Imada Kouji, then this music video starring entirely by the personnel.

In this music video, Girls' Generation is required to act melancholy. Their expressions tell a girl who was waiting for someone very precious to him.

Different from the "Gee" and "The Boys", the song is nuanced ballad. Lyrics of the song itself tells the person who did wrong to make amends by using a time machine.

"Time Machine" is taken from the Japanese repackage album "Girls' Generation" was released in December last year. The song was also used as the theme song ad Nodoame Perman E-ma in Japan.
