The Superior line, eventually with multiple calibers, launched in 1976. It had a movement with an accuracy rating of 5 seconds per year at its peak, among the best Seiko has ever produced.

From Seiko V.F.A to Superior

Seiko's quartz V.F.A. (Very Fine Adjusted) and the Superior line were the leading Quartzes of the Seventies. In 1971 calibers 38SQW V.F.A. (or 3823) and 39SQW V.F.A. (or 3922/23) were the true heirs of the Quartz Astron which debuted in 1969 (these were only produced in 100 pieces costing JPY 450,000).

Right after the limited run of the Astron Quartz Seiko ran development in two parallel competing streams, with the Suwa factory initially producing the 35SQW series and the Daini factory the 36SQW series. However, these developments turned out to be a very expensive and complicated production, so the 35SQW was soon replaced by the 38SQW series running at 5s per month. Daini replaced the 39 series with 36SQW.

Pricing was insane initially, at the introduction in the catalogue of 1974 the 18 karat gold 38SQW V.F.A. would bleed you dry for 1.3 million JPY or the price of a small affordable yacht. It would be about 34000 dollars nowadays. But then, Seiko did not spare any expense in the design of the watch. It has the individually assembled minute markers, which later became famous on any Superior. It also uses the very thin (probably lacquered) black pencil hands that were common on the high end Seikos of the period.

Fortunately, the stainless steel 38SQW became available to the general public at a comparatively affordable price of just 150000 JPY or 4000 dollars. Later on – somewhere in 1976 - the 3823 was to be replaced by the 3883 and 4883 calibers, these demanded (again) the premium price at almost double the value at 220000 JPY. (While the 3823 was reduced to a much more affordable JPY 135,000.) This meant that the 3823 achievement was beaten price wise and spec wise at a 2s per month rating. Sadly this got beaten again after just a year at the top by the 1s per month 4883 Superior.

Twin Quartz 9980/9983

However, as the fanatics at Seiko still sought room for improvement, the Seiko 1978 JDM catalogue debuted the twin quartz caliber - symbolized by the double honeycomb, proudly showing this embossed on the crown and applied on the dial. And if that was not enough, there were (eventually) at least three different design technologies behind these models. The rationale was that while quartz based watches are extremely accurate compared to mechanical watches, they are still not perfect, one of the main reasons for the inaccuracy in a quartz model is that temperature fluctuations change the oscillation of the quartz crystal to vary ever so slightly. This change in oscillation will cause the slight drift in timing. To compensate for these changes quartz watches will employ some kind of temperature compensation.  

In all five different superior and non-superior calibre series were introduced in less than two and a half years. The Superior 9980 and -83 series, first released in August 1978, the 92 Grand and King Quartz series released in December 1978, closely followed by the 97 King Quartz series released in October 1979 (9722A, 9723A).

Just under a year later the 96 Superior and Quartz series were released in September 1980 as caliber 9641A and 9642, the latter in the inconspicuous Seiko Quartz - a true wolf in sheep’s clothes. Hot on its heels was the 94 Superior (9481/83), but also the Grand, King and Quartz series were released in November of 1980 (respectively 9461, 9443 and 9441). And yes, there was also the maverick Lassale 9442.

The Superior line however, caliber 9983, was a movement with an accuracy rating of 5 seconds per year, among the best Seiko has ever produced. At that time, the Grand Quartz line from Suwa also benefits from this twin quartz innovation with the twin 9943 and the 9940 Grand Quartz caliber - retiring the caliber 4843 (likewise the 4883) that had just been selling for two years (1976-1978). The most expensive models however, still are and always were in the Superior line. With a price tag of 235,000 JPY for the 9983 you would be paying about 4700 dollars nowadays.
