Specifications from SBGA283G | Grand Seiko

Selling my Grand Seiko Heritage Spring Drive SBGA283 to free up some room in my collection. Bought new in 2020 from a gray-market seller and have all the boxes, papers, hangtag, and some of the original stickers. Sparingly worn and usually on straps, so the bracelet is like new, and the case has some scratches that can be seen in the photos. Shipping is included for CONUS, may be willing to meet in person if you're in the northeastern US.
