Verified Owner Comments: I had a 556i several years ago. It was a great watch, but this is a step up in every department. The chunky bezel works better in 40mm format, the silky deep black dial even more satisfying sans the 'automatik' text, and the same great satinized case has been hardened and packed with Sinn's tech.
Even the strap is great. When I first saw the design I thought the 4 o'clock date placement was an odd choice, but it actually works really well. This watch is pretty close to prefect. Love it.
