A clean, understated dress watch from Seiko's quartz era, the 7123-8340 pairs a crisp white dial with classic Roman numerals and dauphine-style hands for a timeless, formal look. The slim round case and mixed-finish five-link bracelet give it an elegant presence on the wrist. The dial and crystal are in excellent shape, making this a very wearable piece of late-1970s or 1980s Seiko history.

ConditionOverall this watch presents in good to very good condition for its age. The dial is remarkably clean with no spotting or discolouration, and the crystal is largely free of visible scratches. The case and bracelet carry light to moderate surface scratches and swirl marks consistent with regular vintage wear — no dents, gouges, or significant damage. The case back shows some tool marks from previous battery changes, which is entirely typical. Please review the photos carefully as they form part of the description.

Service & Working ConditionThe watch has been tested and is running accurately. A fresh Renata 390 silver oxide battery has been fitted and the movement appears clean with no signs of corrosion or leakage. Ready to wear straight away.
