Ac the watch

Hi Guys,

I recently went on the AC4 THE WATCH and I have been trying to do the ''Master of Recruitment'' mission. When I click on it, it says ''you will now receive 3 unique codes for AC THE WATCH to give away to your friends.''

So my question is where do I receive these 3 codes? I can find them anywhere.

Please reply with a helpful answer.

Thank you.
