About This Timepiece
Pre-Owned 40mm Grand Seiko GMT 50th Anniversary (SBGN009)
This limited edition Grand Seiko GMT pays tribute to the watch that introduced high-precision quartz timekeeping to the world. The original Astron forever changed the industry, and this commemorative model celebrates that legacy with Grand Seiko’s latest high-accuracy quartz movement, the GMT caliber 9F86. As part of the Heritage Collection, it stands as both a technical and historical statement. The case features Grand Seiko’s signature distortion-free mirror polishing, giving it a beautifully crisp and refined presence. The deep blue dial is adorned with a subtle pattern inspired by the quartz crystal symbol long associated with Seiko’s quartz watches, serving as a quiet tribute to the Astron’s lasting influence. Gold accents highlight the seconds and GMT hands, the 24-hour numerals within the minute track, and the Grand Seiko name, adding contrast and warmth to the design. The case back is engraved with the Grand Seiko lion alongside the quartz crystal emblem and the inscription “Quartz Watch 50th Anniversary.” Limited to just 2019 pieces worldwide, each example is individually numbered, underscoring its collectible status.
