Pre-owned Grand Seiko Sport Collection ref. SBGN027 (2026) proves that a quartz watch can be every bit as impressive as its mechanical counterparts. At its heart is Grand Seiko’s renowned caliber 9F86, a high-precision quartz GMT movement capable of maintaining an astonishing accuracy of ±10 seconds per year. Designed with travelers in mind, the independently adjustable local hour hand allows time zones to be changed without interrupting the movement’s exceptional accuracy, while the dedicated GMT hand and 24-hour scale make tracking a second time zone effortless. The sporty stainless steel case features crisp brushed surfaces, a matching 24-hour bezel, and a radial-pattern black dial that gives the watch a bold, purposeful appearance. A screw-down crown and 200 meters of water resistance ensure it is ready for adventure, while the straightforward three-link bracelet keeps the design clean and versatile.
