King Seiko 45KS 4502-7010 Hi-Beat 36000 (4502-7010). Current Prices, JDM Listings, Market Analysis

The King Seiko 45KS 4502-7010 Hi-Beat 36000 is a vintage JDM dress watch from Seiko's premium King Seiko line, produced during an era when the brand competed seriously with Grand Seiko for collector attention. The reference sits in the 45KS family, a designation that points to the 45mm-class case series Seiko developed for the domestic Japanese market. Tonbo tracks this reference because it surfaces regularly in Japan at prices that don't always align with what US buyers pay. At a current US median of $650, the 4502-7010 price represents a mid-tier entry into vintage King Seiko collecting.

Current US Market Value

The US median for the King Seiko 45KS 4502-7010 Hi-Beat 36000 sits at $650, with the middle half of transactions falling between $450 and $900. That's a wide interquartile range, which typically signals condition variance rather than model inconsistency. The comp quality here is rated 🟡 Limited, meaning this estimate is built on a sample of only four transactions. Four data points are enough to establish a rough baseline, but not enough to treat the median as a firm price anchor. Buyers using the $650 figure should treat it as directional guidance, not a validated market rate. As more transactions clear, the picture will sharpen. For a watch with this level of JDM supply, the US comp pool is thin relative to what's actually available if you know where to look.

Active JDM Listings

Japan is currently showing meaningful supply for the 4502-7010, with six listings appearing in the past two weeks across multiple platforms. Prices span a wide range, from very affordable examples with unknown condition to well-presented pieces priced closer to or above the US median. Anyone considering buying 4502-7010 in Japan should note that condition disclosure varies significantly by platform.

• ¥198,000 on Yahoo Shop (condition listed as excellent) , well above typical US pricing at current exchange rates
• ¥120,000 on Mercari (condition unknown) , roughly in line with upper US market range
• ¥88,000 on a Japanese platform (described as working) , condition language here is minimal, which warrants caution
• ¥54,300 on Mercari (condition unknown) , sits inside the US interquartile range depending on exchange rate and fees
• ¥14,300 on a Japanese platform (condition listed as excellent) , an outlier worth noting, though listings at this price often have undisclosed issues or are relisted quickly

The spread from ¥14,300 to ¥198,000 in a two-week window reflects how fragmented JDM pricing is for this reference. Platform, seller type, and condition description all drive significant price differences.

Recent Alert History

No strict buy signals or opportunity alerts have fired for the King Seiko 45KS 4502-7010 Hi-Beat 36000 in the past 90 days. That's an honest read of the data, not a gap in coverage. With a limited US comp pool and wide JDM price variance, the conditions for a high-confidence alert are harder to meet for this reference than for models with deeper transaction histories. Tonbo's alert engine is conservative by design , it doesn't flag something as an opportunity unless the pricing case is clear. Subscribers watching this reference via Tonbo's signals feed will be notified when a qualifying listing appears.

Japan vs. US Price Gap

The King Seiko 45KS 4502-7010 Hi-Beat 36000 is a JDM-only reference with stronger name recognition among Japanese collectors than US buyers, which historically keeps domestic Japan pricing higher on dealer and shop platforms while auction and fleamarket listings can undercut significantly. The ¥14,300 listing at excellent condition is the kind of outlier that drives arbitrage interest, though low-priced listings on Japanese platforms frequently carry undisclosed dial or case damage that only becomes apparent after purchase. The main risk here is condition variance compounded by thin US comps. With only four US transactions on record, a single transaction involving a rough example can pull the median down in ways that don't reflect what a clean piece would actually fetch. Buyers exploring 4502-7010 for sale listings in Japan should weight condition disclosure carefully and factor in servicing costs before comparing against US prices.
