Ok, i’ve got the perfect solution;
Take a leave of absence from work, go to Swiss land, then establish yourself as a plausible ‘visiting business man’.
Flash a bit of cash around, be seen in all the night spots, then, when your character is firmly established, attempt to befriend the CEOs PA.
When you have gained her confidence, find out what his favourite TV programme is, and check when the programme is being shown.
At a crucial point in the show, knock on his door and run away.
They really hate that, them CEOs.
Then go back home, and resume your former life as if nothing has happened, and e-mail him again, suggesting that he should attend to your dodgy watch or you’ll do it again.
