King Seiko 45KS 4502-7000 Hi-Beat 36000 (4502-7000). Current Prices, JDM Listings, Market Analysis
The King Seiko 45KS 4502-7000 Hi-Beat 36000 is a vintage JDM dress watch from Seiko's premium King Seiko line, beating at 36,000 bph and built for the Japanese domestic market during an era when Seiko was producing some of its most technically serious mechanical work. It sits in the collectible mid-tier of the vintage Seiko market, where condition and dial integrity drive value more than almost any other variable. The 4502-7000 is tracked here because it surfaces regularly enough on Japanese platforms to generate useful pricing data, and the US-Japan spread creates occasional acquisition opportunities for buyers willing to source direct. At a current US median of $650, it occupies a price point that attracts both entry-level vintage Seiko collectors and more experienced buyers hunting specific references.
Current US Market Value
The King Seiko 45KS 4502-7000 Hi-Beat 36000 carries a current US median price of $650, with the interquartile range running from $450 on the low end to $900 at the top. That spread is wide relative to the median, which tells you condition variance is doing most of the work here. It is worth being direct about the data quality on this reference: the comp set is built from five recorded transactions, which earns a 🟡 Limited comps rating. That means the median is a reasonable orientation point rather than a statistically confident benchmark. If you are researching the 4502-7000 price for a purchase or sale decision, treat the range as directionally useful and weight recent Japanese listings heavily when calibrating expectations. Additional sales data will sharpen this picture over time as more transactions are recorded.
Active JDM Listings
Japan is currently showing active supply for the 4502-7000, with four listings appearing across multiple platforms in the past two weeks. Prices in yen span a meaningful range, and at least one listing explicitly notes condition issues, which is worth flagging for buyers considering import. Here is what the recent JDM market looks like for this reference:
- Jun 03, Mercari Japan: ¥57,000 (condition unknown)
- Jun 03, Yahoo Japan: ¥76,780 (condition unknown)
- Jun 01, Yahoo Flea Market: ¥93,500 (listed as a little damaged and dirty)
- May 21, Mercari Japan: ¥79,100 (condition unknown)
The spread from ¥57,000 to ¥93,500 across these listings reflects both condition differences and seller pricing variability rather than any single clean market price. The lowest-priced listing on Mercari is worth particular attention for buyers comfortable with the sourcing process, assuming condition holds up under closer inspection. If you are looking for the 4502-7000 for sale from Japan, Mercari and Yahoo Flea Market are the two platforms generating the most recent supply.
Recent Alert History
No strict or opportunity alerts have fired for the King Seiko 45KS 4502-7000 Hi-Beat 36000 in the past 90 days. This does not mean the reference is inactive, as the JDM listings above confirm it is moving through the Japanese market. It simply means that recent prices have not crossed the thresholds that would flag an exceptional deal or a below-floor buy. For a reference with limited US comps and moderate trading frequency, alert signals will be less frequent than for higher-volume references. When one does fire, it is worth acting on quickly.

Japan vs. US Price Gap
The gap between Japanese platform pricing and the US median on the 4502-7000 is real but not dramatic. At current exchange rates, the lower-end Japanese listings convert to roughly $370 to $500 USD before shipping, import fees, and any service costs, which leaves workable margin against the US market median of $650 if condition is solid. The main risk on this reference is not sourcing logistics but condition variance. With only two of the four recent listings offering any condition description at all, and one of those flagging damage, buyers sourcing blind from photos need to price that uncertainty into their offers. The limited US comp sample also means that a watch in genuinely excellent condition may command closer to $900, while a tired example could settle well below the $450 floor.
