Seiko Astron NEXTER Solar Radio SBXY027 (SBXY027). Current Prices, JDM Listings, Market Analysis

The Seiko Astron NEXTER Solar Radio SBXY027 is a GPS solar radio timepiece from Seiko's Astron line, positioned at the technology-forward end of the brand's domestic Japanese catalog. It surfaces regularly in JDM channels, which is why Tonbo tracks it as a candidate for cross-market sourcing. At roughly $982 on the US secondary market, it sits at a price point where Japan-to-US arbitrage can be meaningful, depending on condition and timing. The data below reflects what the market actually shows right now, not projections.

Current US Market Value

The current US median for the Seiko Astron NEXTER Solar Radio SBXY027 SBXY027 sits at $982, with a p25-p75 range of $982 to $982. That flat range is a function of sample size, not price stability. This SBXY027 price estimate is drawn from a single verified eBay comp, which Tonbo classifies as 🟢 Verified. One confirmed sale is enough to anchor a directional figure, but it is not enough to establish a reliable price distribution. Treat $982 as a reasonable working reference while understanding that a second or third comp could shift the picture. Anyone researching SBXY027 for sale in the US should monitor for additional transactions before drawing firm conclusions about the going rate.

Active JDM Listings

Japan is showing meaningful supply right now. Six listings appeared on May 30 alone, spread across Yahoo Shopping and Yahoo Flea Market, with prices ranging from ¥79,002 to ¥132,000. That spread is notable. The lower end of that range, at ¥79,002, appeared twice on Yahoo Shopping in unknown condition. The upper end, at ¥132,000, is likely a new or near-new example from a shop with higher margin expectations. For anyone looking to buy SBXY027 from Japan, the current listing environment offers genuine selection.

• ¥79,002 twice on Yahoo Shopping, condition unknown
• ¥98,000 three times on Yahoo Flea Market, listed as new
• ¥99,000 on Yahoo Flea Market, listed as new
• ¥132,000 on Yahoo Shopping, condition unknown

The cluster of new-condition flea market listings between ¥98,000 and ¥99,000 suggests these may be individual sellers clearing retail purchases. That is worth noting because new-in-box JDM stock at those prices, if condition holds up on inspection, represents the more attractive end of the current supply. Tonbo's signals feed tracks movements like this in near real time.

Recent Alert History

No strict or opportunity alerts have fired for the SBXY027 in the past 90 days. That is an honest read of the data, not a gap in coverage. It means that during this window, no individual listing crossed the thresholds Tonbo uses to flag actionable price events. The current JDM listings visible above may represent the early stage of a more active period, but as of now the model has not triggered a signal. Buyers who want to be notified the moment an alert-worthy listing appears can set up tracking through Tonbo's deals tracker.

Japan vs. US Price Gap

At a ¥/$ exchange rate in typical recent ranges, the lower JDM listings in the ¥79,000 to ¥99,000 band convert to roughly $500 to $650 USD before shipping, import fees, and any intermediary service costs. Against a US reference of $982, that gap leaves room for a positive outcome on a clean transaction. The main caution here is comp thinness on the US side. A single American sale is not a deep market, and the actual price a seller achieves on any given day can vary more than a tight comp range would suggest. Condition variance on the Japanese side adds a second layer of uncertainty, particularly for the listings marked with unknown condition. Standard JDM sourcing risks apply throughout.
