For sale is my lightly used Sinn 103 St A. I purchased this piece secondhand and have owned it for little over a year. I wore it a few times, as did the previous owner, but you can tell this watch has never been worn heavily. The condition of the case is in very good condition. The acrylic crystal is in great shape, no major dings or scrapes. I always kept it clean with polywatch. This watch was built in 2016 so it should have the ETA 775 inside. But I have not had the caseback off to check. Watch is running well and all chronograph and day/date functions are working perfectly. I will update this ad with a 24hr test on accuracy. The warranty card is dated 2016. The current model sold by Sinn/watchbuys is identical to this watch (except that the current offering is probably not ETA anymore). Here are some links on this model: https://www.sinn.de/en/Modell/103_St.htm https://www.watchbuys.com/store/pc/Sinn-103-St-Acrylic-on-Bracelet-103p291.htm The watch comes on the original H-link bracelet from Sinn. Bracelet shows more scratches and wear than the watch, it was previously used on a Sinn 104. Still in great used shape. It comes with the normal Sinn tool as well as the hex wrench for the links. The extra links are included as well as an extra 103 end link. Both the inner and outer box are included. Asking $1550 shipped and insured to CONUS. Not interested in international sales at this time. Please no trades. Zelle or Venmo preferred, Paypal with great references, or in-person deal in/near CT. I have bought and sold through WUS and on WatchExchange (same username). More pictures, videos, references or details on request.
