This timepiece is a magnificent artifact from September 1974, as definitively proven by the serial number 492789.The 38-series stands as one of the most historically significant families in horology, representing Seiko's first full-scale commercial success following the 1969 Astron. It houses the legendary Caliber 3863, a high-grade mechanical soul from an era when electronic movements were hand-soldered and over-engineered with robust metal trains to maximize longevity.
The architecture is outstanding, featuring a solid stainless steel cushion-style case with sweeping polished lugs that integrate cleanly into its original multi-link bracelet. The dial is an absolute work of art, sporting a rare olive green sunburst finish accented by thick, three-dimensional faceted indices and a bilingual English/Kanji day-date window. Notably, it displays the rare, early applied 3D "Cube" quartz crest at 6 o'clock Seiko's elite internal badge of electronic mastery before the standard honeycomb logo was adopted. Turning the watch over reveals a prominent external coin-slot battery hatch engineered for quick, seamless power cell swaps.
