1979 when the quartz crisis was in full bloom SEIKO released the 9983 movement, a HAQ (high accuracy quartz) with double quartz crystals and thermo compensation. Specs are +-5 seconds/year and this model cost about 3 times as much as a Rolex Submariner the same year. +-5 spy is still 2016 the best spec available for a quartz watch.

The 9983-8000 is one of the two original models released 1979 and it is of course very rare to find today .
The integrated bracelet and the coarse surface makes it a real stunner imho. The all applied markings of the dial look great and the dial structure resembles paper.









During the 60s there were accuracy competitions in Switzerland, mainly for Swiss made watch brands but SEIKO started participating since the competitions were open to all brands. Late 60s SEIKO started winning the competition which ultimately led to the death of the competitions and the start of COSC which is Swiss made exclusive. What makes it even more impressive is that SEIKO used their general production watches while many brands only entered with special watch movements made for the competitions.
I received this watch today and was worried that the crystal wasn’t original since its domed and not flat like on my other KS. Well guess what, my son smashed it and it turns out it’s plexi. SEIKO crystals are hardened and don’t shatter like this. Bad timing but forced me to buy an original crystal for it.
