I'm not really an accuracy whore since I change my watch out every couple of days or a couple times a day, but the Sinn seems to be right on the money everytime I check it and with the gloss dial and large white markers it's super legible. Actually it's probably the most legible watch I've owned. Quality wise I would rate it somewhere between Longines and Omega. The watch head is fantastically done and the movement is beautiful, but the bracelet clasp is a little thin and tinny feeling (where have we heard that before..cough, Rolex, cought). From what I've read, the movement can come decorated or not, so it's kind of a mixed bag on what you're gonna get. I've thought about selling it a time or two, namely right after I got it, but it's slowly finding its way into the collection because I just can't seem to take it off when I wear it. The outer ar coating hasn't been near the problem it seemed to be on the PO and U1. Not sure if it's the smaller crystal or what but it stays smudge free most of the time.
Anyways, I know I'm kinda rambling here, don't really do these at all, but the short of it is the Sinn 556 is a sweet little watch. At 38mm it's cool without trying to be cool
. I've worn this exclusively on the bracelet so far but when the weather cools down I may strap it on a leather I picked up from Gerry. Thanks again Gerry! Sorry for the sucky pics. For some reason ever since moving I just can't find a decent place in the house for pics. I even pulled the light box out and this what I get, sheesh. Anyway, thanks for reading and I hope this helps at all! 
i need to stay away.
