This timepiece is a magnificent artifact from December 1987, as definitively proven by the serial number 701240.
he Chronos line was introduced by Seiko in the 1980s as a highly refined collection bridging daily wearability with high-end, geometric design cues. This reference houses the ultra-slim Caliber 9021, a technical soul engineered for a thin profile that allows the Tank style case to sit seamlessly against the wrist.
The architecture is outstanding, featuring a rectangular stainless steel case that frames a stunning rice paper textured dial. This intricate, micro-patterned finish provides an elegant, organic visual aesthetic deeply rooted in traditional Japanese craftsmanship. Flipping the watch over reveals the clean caseback engraved with the Seiko Quartz "S" emblem, confirming its status as a professional-grade instrument from the golden era of Japanese quartz development. Paired with its original, beautifully integrated mesh bracelet, it delivers an unmistakable retro-futuristic elegance.
