Up for sale is my Sinn 556a RS which I purchased here on [r/watchexchange](https://www.reddit.com/r/watchexchange/) a couple years ago. It is in excellent condition, case and crystal are clean. It’s currently on a hybrid nylon/silicone strap but comes with the original Sinn leather strap as pictured. No H-link bracelet for this particular piece. $995 shipped in the CONUS Payment via Zelle preferred Album [https://imgur.com/a/7Tt4SNy](https://imgur.com/a/7Tt4SNy) Timestamp [https://imgur.com/a/kNASDJc](https://imgur.com/a/kNASDJc)
