Collector’s Note: Why This Watch Is in High Demand
Direct Precursor to the Grand Seiko 62GS: The Caliber 6218 is celebrated among Seiko collectors as the direct structural foundation for the movement used in the iconic 62GS (Cal. 6245/6246)—Seiko’s first-ever automatic Grand Seiko.
High-Grade 35-Jewel Architecture: Unlike standard Seikomatic models of the era, the 6218 features a high jewel count (35 Jewels), hacking seconds mechanism, fine adjustment micro-regulator, and manual winding capabilities.
Symmetrical & Timeless Dial Layout: The full day-of-the-week window at 6 o’clock paired with the date at 3 o’clock creates one of the most balanced and aesthetic dial designs in 1960s horology.
1964 Tokyo Olympics Era: Manufactured in October 1964, this piece dates directly to the historical epoch when Seiko introduced its finest mechanical Innovations to the global stage.
