INFINITE unveiled the first photo teaser for "Clock."

Last week, Woollim Entertainment confirmed INFINITE is making a full group comeback with all members (except Sunggyu, who's currently in the military) in February. 

The boy group will be returning with the digital single "Clock" which was first revealed at their year-end fan meeting. This is INFINITE's full group comeback in about a year. 

The official release of "Clock" will be on February 13.
