Cumberbatch managed to beat last year's sexiest man alive, Ryan Gosling, who only came in at number 4, and also overcame Jude Law, fellow Brit Henry Cavill, and James Bond star Daniel Craig, who finished at number 24 in the Empire magazine conducted poll, reported E! online.
Watson also beat an impressive list of Hollywood bombshell's which included Mila Kunis, Cameron Diaz, Emma Stone, Olivia Wilde and star of upcoming comedy "Don Jon" Scarlet Johansson, who came in at number 2.
Cumberbatch was highly amused by the poll's outcome and said, "It puts a bit of a spring in your step. It's nice, you swagger a little bit, it's enjoyable. I've punched well above my weight this year... I find it hysterically funny... It's a giggle. I wield it with a massive smile."
Watson and Cumberbatch have had a busy and successful year in 2013.
