Thank you for viewing. "SEIKO/Seiko Superior 4883-8000, Working Condition" This item belonged to my grandfather and was part of his collection. It has been used sparingly, and for a vintage item, the crystal and case have very few noticeable scratches, making it an extremely beautiful piece. The belt is a third-party mesh belt from Maruman. The battery was replaced in May of this year, and its operation has been confirmed. It keeps time almost perfectly, and is still running accurately. (Although I haven't measured it precisely, the time has been correct, so it's probably off by only a few seconds over six months.) Please refer to the images for details and purchase if you understand the item. 【Description】 The Quartz Superior was introduced in 1974. While typical quartz watches of the time had a monthly accuracy of 15-20 seconds, this model boasted a high-precision of ±1 second per month. It also had a battery life of over two years, improving practicality compared to previous Superiors. It was popular as a high-spec model that achieved high accuracy. The dial is a silver dial with a guilloché finish to prevent light reflection. The indexes are applied every minute, and onyx is used every five minutes, making it a high-end specification. It has a day-date display at the 3 o'clock position, and is equipped with a quick-change function via the crown (date: forward, day: backward). The day of the week can be switched between English and Japanese. Time adjustment is possible by pulling the crown one more step, and the hacking (seconds hand stop) function has also been confirmed to be working. The case material uses "VFA (Very Fine Adjusted)" grade hard stainless steel, enhancing its magnetic resistance. It is equipped with non-reflective coated glass, and both its specifications and details are excellent. This 4883 Superior has a slightly more substantial form compared to the 9983 Seiko Superior Twin Quartz. Since the battery has been replaced, you can use it immediately upon arrival. It is a gem recommended for daily use, as well as for those looking for high-precision Seiko quartz watches or vintage watches. At the time, Grand Quartz, which followed the names of GS (Grand Seiko) and KS (King Seiko), cost 84,000 yen, and King Quartz cost 74,000 yen. This watch, however, was a dedicated timepiece that cost 180,000 yen. 【Size】 Case (approx.): Diameter 36 x 45mm Weight (approx.): 84g (including belt) Belt length: Adjustable * It still has room to spare, adjusted to my wrist size of 18cm. 【Shipping】 It will be wrapped in bubble wrap and shipped via Rakuraku Mercari courier service, Takkyubin Compact.
