Seiko Superior 4883-8100

The Seiko Superior 4883-8100 is a very special and technologically advanced quartz wristwatch model from Seiko, created 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-level and more precise quartz processes. The watches in this series generally have more advanced mechanisms, better workmanship and more stylish designs. "Twin Quartz" technology was separated by Seiko in the late 1970s and was a technology that significantly improved the features of quartz watches. In this technology, there are two separate quartz crystals in the mechanism. One of these crystals is used to report timekeeping errors caused by temperature changes. This allows the watch to keep much more precise time. The product you are reviewing was manufactured in 1978.

PROFESSIONAL FULL SERVICE. Since the mechanism is completely disassembled, every part is cleaned, lubricated and its temperature is adjusted, your watch works without any negative surprises. (No maintenance for 3 years unless exposed to death.)
