 Rare, unusual looking 1978 Daini twin quartz Seiko Grand Quartz high end high accuracy watch in good condition. 

Caliber 9256 was short lived, only 3 years, Daini developed twin quartz caliber, similar to Suwa 9943. Both use dual quartz to compensate for changes in temperature that affect accuracy. Both were rated at +/- 10 secs per year. 

This model was quite expensive in 1979 with a price tag of 110,000 yen. 

Bold looking case has very strong, sharp lines and angles with a nice mix of brushed and polished surfaces.

Under the sapphire crystal lies expensive looking white brick dial with applied how markers, Seiko logo and twin quartz logo. 

There are few very small scratches here and there but overall condition is excellent. 

Full size original bracelet is also in very good visual condition, however there is little extra wiggle room between 2nd and 3rd link from the bottom end of the watch. Nothing is broken, just little loosend, so the braclet folds rather than curves on that section. 

Calendar has weekday in Kanji and English. 

Watch has been disassembled and cleaned.
