I’d go with Kari. This isn’t an easy decision. Rexhep will undoubtedly become a legend in horology and having one of his early pieces will go a long way. I vote for Kari because you can design the entire watch. He also will work with you and give you ideas as well. It is truly artisan. I believe his finishing is comparable to Rexhep, but Rexhep has a slight edge. However, the dial options and customization creates the separation and gives Kari the advantage. I should also state that I do own a Rexhep piece. I held an AK-06 in my hand nearly 2 years ago. I didn’t like it, but it has grown on me and now I do. The case is an acquired taste, but it is distinctive. It was actually the dial that I wasn’t excited about. The AK-06 is a hot item and there will only be 50. One might argue, with Kari, there is only one! The one YOU design. Kari has proven himself as a legend and one of the top watchmakers of our time. Good luck with your decision!
