A few months ago, Bas van Dorp wrote a small review on his Sinn EZM1 , which you can read here. Just a few minutes ago, I noticed that Hans Mennink wrote a Sinn EZM1 review as well, which can be found here. Hans has written some truely great articles on Christiaan van der Klaauw watches as well, but I am afraid these are only in Dutch.
