I just took delivery of my first Sinn, a (used) 656 on metal. I love the simplicity of the dial and the absolutely stunning contrast. I also appreciate that, in an industry where the trend seems to be toward strapping a wall clock to your wrist, Sinn (among others) still produces watches that don't overwhelm my average 7 in wrist. The Sinn comes to replace my daily wear for the last 8 years, a Citizen quartz chrono that finally gave in. Instead of throwing money at it to replace the o-rings and adjust the chrono reset position, I bought a new watch. A good change in my opinion and I expect that it will hold up well to continual use as they have a good reputation for being rugged. Anyway, you have all seen them before, but I will post a pic or two when I get the chance.
