Hi [](https://www.reddit.com/r/watchexchange/), Long-time lurker, looking to jump in. First time, so let me know if I made any mistakes.   Up for sale is a Grand Seiko Spring Drive GMT ref. SBGE277.  The watch has a black and white bezel and a textured black "volcanic" rock dial inspired by the Hotaka mountain range in Japan.   Overall, the watch is in mint condition with virtually no signs of wear.  Watch has been resized but includes the 1 link that was removed.  The watch comes as pictured with papers dated June 2022 & inner/outer boxes.   Thanks to Grand Seiko’s unique Spring Drive caliber, the seconds hand glides silently and smoothly, with no ‘tick’, across the dial (see video in Image Gallery).  The power reserve is 72 hours when fully wound and is shown on the discreet indicator next to the eight o’clock marker. The GMT hand allows a second time zone to be shown and the hour can be adjusted without compromising the one-second-a-day precision of Spring Drive. **Images & Timestamp:** [https://imgur.com/a/siSdjkn](https://imgur.com/a/siSdjkn) **Price/shipping:** Asking for **$5,200 OBRO -** includes insured shipping with tracking info within CONUS.   I take bank wire, Zelle, Venmo, and PayPal F&F.   No Trades Please.   All Sales Final.   **Additional Watch Details** **Case** Case Material : Stainless Steel Case Diameter : 44mm Case Thickness : 14.7mm Case Length : 50.8mm Lug Width : 21mm Dial Color : Grey Crown : Screw Down Strap/Bracelet : Stainless Steel w. three-fold clasp Crystal : Dual Curve Sapphire Caseback : Stainless Steel **Movement** Caliber : 9R66 Type : Spring Drive Power Source : Automatic Jewels : 30 Accuracy : ±1 second per day / ±15 seconds per month (average) Duration : 72 Hours **Functions** Features : Time, Date, Power Reserve Indicator, GMT Water Resistance : 200m Magnetic Resistance : 4,800 A/m
