Introduction Offered here is a discontinued Seiko Grand Quartz, an iconic high-grade quartz watch from Seiko’s golden era of precision engineering. Distinguished by its sharp decagonal (10-sided) stainless steel case and refined silver dial, this model reflects the confident design language and technical ambition of late-1970s Japanese watchmaking. Historical & Collector Value The Grand Quartz line was introduced as Seiko’s elite quartz series, positioned just below Grand Seiko and produced entirely in-house. During this period, Seiko led the global quartz revolution, setting new standards for accuracy and reliability. This reference is now out of production, and surviving examples are increasingly scarce on the market. Particularly noteworthy is the Kanji / English day-date display, originally intended for the Japanese domestic market. Today, Kanji calendar models are highly sought after by international collectors, adding both cultural and collector value to this piece.
