Seiko - Chronos Brushed Silver Dial Tsunami Caseback - 8123-6730

This exceptionally crisp vintage sports-dress instrument is an authentic JDM artifact from February 1986, as definitively verified by the serial number 621145 stamped across the stainless steel screw-down caseback alongside the revered relief Seiko Tsunami Wave medallion. The caseback proudly features historical commemorative corporate provenance engraved for 25 years of service at Shinko Electric Co.Ltd. adding rich Japanese industrial heritage to the piece. Positioned in Seiko’s respected Chronos line, this reference delivers refined mid-1980s executive geometry backed by genuine tool-watch resilience. It houses the reliable Seiko Caliber 8123 quartz movement, an over-engineered multi-jeweled engine renowned for high accuracy, low maintenance, and a bilingual English/Kanji quickset day-date calendar complication.

The case architecture presents a solid stainless steel chassis defined by sharp angular hooded lugs, vertical brushed finishes across the top surfaces, polished side facets, and a smooth fixed bezel. The dial is a masterclass in clean minimalist balance, showcasing a fine vertically brushed silver surface appointed with applied faceted baton hour indices featuring black center accents, matching pencil hands, an outer minute track, and a framed quickset day-date window. Fitted to its original, period-correct factory Seiko-signed stainless steel bracelet with signed folding clasp and correct YA20A end-links, this 1986 JDM heirloom delivers cohesive, comfortable wrist presence.
