Seiko Superior 9983-8000

The Seiko Superior 9983-8000 is a very special and technologically advanced quartz wristwatch model that Seiko produced in the late 1970s. This watch is especially known for its "Twin Quartz" technology and reflects Seiko's pursuit of technological perfection at that time. Seiko Superior is a series that includes Seiko's higher-end and more precise quartz watches. The watches in this series generally have more advanced mechanisms, better workmanship and more stylish designs. "Twin Quartz" technology was a technology developed by Seiko in the late 1970s that significantly increased the precision of quartz watches. In this technology, there are two separate quartz crystals in the mechanism. One of these crystals is used to compensate for timekeeping errors caused by temperature changes. This allows the watch to keep much more precise time. The product you are reviewing was produced in 1978.
