Up for sale is my Sinn 857 UTC, neo-vintage circa 2007, ETA movement caller GMT movement, tegimented, anti-magnetic, and on tegimented bracelet. It's from a time when they didn't always print "Made In Germany" on the dial, or always include the tegimented symbol on the clasp. It comes with all boxes and papers, 7 3/4" of links, and, for some reason, a mini CD that Sinn apparently shipped with their watches at one point. Mechanically its service history is unknown, but it's the most accurate Sinn I've owned, always gaining less than a second a day when worn. I think there's something to be said for the ETA movements of this era. The copper sulfate capsule is somewhere between [25-50% saturation](https://www.watchuseek.com/attachments/copper-sulphate-jpg.8159578/), show in the last picture, and has stayed there for the months I've owned it. This means itwas serviced at a Sinn-authorized location and refilled with the correct inert gas. It also means the gaskets are all intact, I've taken it in the water plenty. It does show wear appropriate for its age, the bezel is mostly clean, I tried my best to capture the wear on the bracelet. I can't see anything too major though. I'm asking $1200 shipped and insured USPS Priority within the US, we'll need to discuss shipping prices otherwise. Thanks for looking :)
