Research in Internet key informations for 50 different brands and recap them in a unique document.
The 50 brands are watches brands (e.g Rolex, Omega, etc...) and for each of them I am looking for the following information:
1) Location of headquarter
2) name of CEO
3) name of CMO/head of marketing&communications
4) Turnover and growth over time
5) Number of watches sold a year
6) Who owns the company
7) Sources of information

Most of brands don't disclose information on size of business except in the form of approximate numbers while doing interviews.

This is to start - I might need more information a second brief.
