■ Buyer's comment
SBJG017 is a memorable piece that is the first reprint of the 1980s masterpiece "Rotocall." The unique operating feel of switching modes by turning the octagonal rotary bezel will be nostalgic for those who know the watch back then, and will seem fresh to younger generations. The compact 37mm size is unisex and can be enjoyed, and the retro digital font is new for today's times. As expected from Seiko, the design is multi-functional yet intuitively operable. Please experience the revival of a masterpiece that remains in watch history for yourself. by Fujimuro
