Grand Seiko Sport Collection SBGN027 Quartz GMT Black Dial Watch
The Grand Seiko SBGN027 is a Sport Collection quartz GMT watch powered by the high-accuracy Caliber 9F86. Its compact 39 mm stainless-steel case, black dial, fixed 24-hour bezel, and independent local-hour adjustment make it a practical travel watch with strong everyday versatility.
The watch features a black radial-pattern dial, LumiBrite hands and indexes, and a dual-curved sapphire crystal with inner anti-reflective coating. Its stainless-steel case combines hairline-brushed and Zaratsu-polished surfaces, while the screw-down crown is positioned at approximately 4 o’clock. The stainless-steel bracelet is secured by a three-fold clasp with push-button release.
The Caliber 9F86 provides an accuracy of ±10 seconds per year, approximately three years of battery life, a date display, and a 24-hour GMT function. With 20-bar water resistance and magnetic resistance of 4,800 A/m, the SBGN027 is built for dependable use while travelling or in daily wear.
