This watch has been my constant companion since 2018. My EZM 1.1 joined me on countless adventures in the watch community, and it feels like a part of me. It has been on my wrist for over 200 web shows, 2,500 watch reviews, SIHH(s), Watches & Wonders, Dubai Watch Week(s) and many more. I wore it during encounters with Philippe Dufour, Claude Sfeir, Rexhep Rexhepi, David Walter, and Max Büsser. It’s been to Dubai, Singapore, Thailand, and Geneva. This Sinn was supposed to be my last watch, and I swore I would never sell it. I’ll be sad to see it go. I hope the winner of this auction loves my Sinn as much as I did.
