For sale is my beautiful Sinn 903 St HB II Limited Edition number 496/500 watch in immaculate condition as you can see from the images and video. The watch is part of a large 20+ collection and has been worn in rotation only a handful of times. Purchased new upon release from CW Sellors it finally arrived in March 2025, these sold out pretty quick so are very hard to come by, this is also the only recently released 903 with no date complication. I am selling due to shrinking my collection and have numerous pieces currently for sale, I am not in a rush to sell but open to reasonable offers. If you have any questions or would like any further images do not hesitate to contact me. I am located in Preston and more than happy to arrange an in person inspection of the piece.
