Most of the common free e-mail providers do not have a block feature. You can mark the unwanted e-mails as spam or create a folder for all e-mail addresses that you do not want to receive communications from to be sent to. It's easiest to just mark them as spam. You will not see them in your inbox after that. 

I've always been very sensitive to the way a watch's movement and its habillage were conceived. By understanding those, you can interpret the link rationale and reason behind the creation of a specific watch. What I try to do is make each link watch that I study talk so that link I can make sense of its origin. My job is about understanding the story of a watch, and then relating it to how people interacted with it both during its conception and after its creation.And this watch provides plenty of clues.
