Watson, who played Hermione Granger in the "Harry Potter" film series, was caught for driving approximately 61 km/h on a road with a speed limit of 48 km/h in Oxford last summer.
England uses a "points system" for traffic offenses and Watson already had nine points when she was caught.
The actress, who did not appear at the five-minute court hearing, was also ordered to pay approximately 14,000 kronor in fines.
She appeared in a total of eight "Harry Potter" films before moving on to films like "Beauty and the Beast", "The Bling Ring", "The Perks of Being a Wallflower" and "Little Women".
