CHALLENGE DESCRIPTION :

I love this watch. It's been with me all over the world, from Istanbul to Shanghai to Macau.I wear it with suits quite a lot. My boss liked it too. I remember wearing it when she died. What is her successor's name?

After reading the challenge description how the heck one can find watch wearing by dead person. It was quiety guessy like being an OO7 fan I cracked it it was just talking about James Bond movie (a little research will also lead you to flag). I just search successor of M in James Bond movie I got this.
