It’s unclear how Benedetto Papi intended for us to tell the time with the watch, although we’re guessing that the parts where the yellow portions meet the black portions might indicate hour and minutes. For example in the picture above, it could indicate that it’s about 2:20
Now if you are wondering where you will be able to get the Pac-in-time watch, the bad news is that it remains a concept watch design for now, unless Namco decides to license Pac Man out or make the watch themselves.
