Los Angeles - John Mayer is considering getting Katy Perry a watch for Christmas.
The acoustic singer is mulling over his options for what to get his Unconditionally hitmaker girlfriend this year, and is reportedly interested in finding a rare timepiece.
A source said: "He's asked a friend who's a rare watch dealer to email him photos of options. John's a great giver, who finds unique presents."
The Your Body is a Wonderland star will have to go a long way to beat last year's gift, when he got her a custom designed guitar covered in intricate designs, including her initials and the date they first met.
A source said at the time: "Since they met he has been trying to prove he isn't the guy everyone says he is.
"This should definitely prove that - every little detail on the guitar shows how much he thinks of her."
Since he started dating Katy in summer 2012, John appears to be a changed man and to have put his womanising days - which saw him date stars including Jennifer Aniston, Cameron Diaz and Jessica Simpson - behind him.
