The shoot took place in Westminster, close to Burberry's headquarters at Horseferry House in Pimlico, and the images capture Watson in a collection inspired by Virginia Woolf and the Bloomsbury set.
"Emma has a classic beauty, a great character and a modern edge. Her charm, intellect and brilliant sense of fun made the whole shoot feel like a picnic on the Thames," Baily told the Evening Standard.
He added: "I felt Emma would be strong enough to hold the campaign as the only girl, and I loved the idea of her being surrounded by these young, cool British guys."
Watson first appeared as Hermione Granger alongside Daniel Radcliffe and Rupert Grint in Harry Potter And The Philosopher's Stone in 2001. The sixth film Harry Potter And The Half-Blood Prince is released on 15 July.
