For sale is my 2020 GS SBGW231, complete and under Factory warranty. This is a manual wind, 37.3 mm case, absolutely beautiful, only worn a handful of times. Really no marks I can see, sets, winds, and runs like butter. OEM GS strap is super comfortable, and shows very little wear. I love this watch, and have had zero issues with it, just a bit to small for me. Price: $3650 net. Overnight/insured shipping in the United States only is included in the price. Payment: Bank wire, Paypal with strong references, and I always welcome a FTF at my office in the Chicago area for cash.
