King Seiko KSK Reissue Black (SPB279, SPB279J1, KSK SPB279). Current Prices, JDM Listings, Market Analysis
The King Seiko KSK Reissue Black is part of Seiko's ongoing effort to revive one of its most respected historical lines, the King Seiko KSK series originally produced during the competitive domestic watch era of the 1960s and 70s. The SPB279 brings that heritage forward in a modern format, with the black dial variant sitting at the more understated end of the reissue lineup. It carries enough name recognition to attract both collectors and general enthusiasts, which is why it appears across both the US grey market and Japanese resale platforms. At its current US median, it occupies a mid-tier price point within the broader King Seiko reissue family and is worth tracking for anyone evaluating the gap between domestic Japanese pricing and US resale.
Current US Market Value
The current US median price for the King Seiko KSK Reissue Black SPB279 sits at $1,150, with the interquartile range running from $974 to $1,318. That spread of roughly $344 across the middle of the distribution reflects a moderate degree of condition and listing variance, which is expected for a modern reissue that circulates across both private sellers and small dealers. The underlying dataset carries a sample size of four verified transactions, which is enough to establish a directional benchmark but not large enough to treat as a settled consensus. Comp quality is rated Verified based on sourced eBay sales data, meaning these are completed transactions rather than asking prices. As volume builds over time, confidence in the range will increase. For now, the $974 floor is the more useful number for buyers, and the $1,318 ceiling is a reasonable reference for anyone pricing a clean example to sell.
Active JDM Listings
Japan market activity for the SPB279 has been thin in the most recent two-week window, with one confirmed listing surfacing as of late May. That listing appeared on a Japanese platform at approximately ¥1,442, though the condition of that specific example is unconfirmed. Single-listing windows are not unusual for this model given its niche position, but they also mean the current Japan-side pricing data carries limited depth. Here is what the recent JDM data shows.
- One active listing recorded on May 30 on a Japanese resale platform
- Listed price approximately ¥1,442 (condition unspecified)
- No additional JP listings observed in the prior two weeks
- Platform attribution confirmed via automated monitoring
- Listing URLs are subscriber-gated through Tonbo Market alerts
Anyone looking to buy SPB279 Japan should note that inventory at this price point tends to move quickly when it does appear, and low listing frequency makes manual monitoring unreliable without an alert layer in place.
Recent Alert History
No strict or opportunity-tier alerts have fired for the King Seiko KSK Reissue Black SPB279 in the past 90 days. This does not mean the model lacks potential, but it does mean the automated monitoring system has not detected a listing that clears the threshold for flagging a clear arbitrage window. For a model with a limited comp pool and sporadic JDM inventory, this is not unusual. Alert frequency tends to increase as more listings enter the dataset and pricing patterns stabilize.

Japan vs. US Price Gap
The primary driver of any US-Japan price gap on the SPB279 is the combination of JDM-preferential pricing at Japanese retail and the relatively thin resale supply on the US side, which keeps grey market premiums in place even for modern reissues. When a clean example appears in Japan at a price like the ¥1,442 listing above, the math can look compelling on paper, but shipping, import handling, and PayPay or proxy service fees narrow that margin quickly. The main risk factor for this specific model is comp thinness. With only four verified US comps in the dataset, a single outlier transaction can shift the median meaningfully, which makes it harder to price with confidence on both the buy and sell side. Buyers evaluating SPB279 price expectations should treat the current range as directional and monitor for additional transaction data before committing at the upper end.
