Singer John Mayer is reportedly planning to buy a rare watch as a Christmas gift for his girlfriend and pop star Katy Perry.
The 36-year-old has taken help of an antiques dealer to buy the timepiece, reports contactmusic.com.
"He has asked a friend who is a rare watch dealer to email him photos. John is a great giver, who finds unique presents," a source said.
Mayer 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.
