For sale is a Sinn 556i in excellent condition (no dings, scratches, and crystal is in flawless condition) for $685 which includes shipping within CONUS. Comes on the original Sinn leather strap and boxes/papers. I bought this secondhand from watchuseek member Clarvonn and literally wore it only once. It was originally purchased in December 2014 from Watchbuys. Haven't done a ton of sales on here, but a couple references below:
