Seiko Astron NEXTER Solar Radio SBXY081 (SBXY081). Current Prices, JDM Listings, Market Analysis

The Seiko Astron NEXTER Solar Radio SBXY081 sits in Seiko's GPS solar line as a Japan-domestic release, meaning it circulates primarily through Japanese retailers and auction platforms before finding buyers overseas. Tonbo tracks this reference because the JDM supply chain creates genuine price differentials worth monitoring for informed buyers. The SBXY081 price in the US currently anchors around $904, based on verified comp data sourced from recent eBay transactions. That single data point reflects a thin US market rather than an illiquid one, and the active Japanese listings suggest meaningful inventory exists for buyers willing to source directly.

Current US Market Value

The current US median for the Seiko Astron NEXTER Solar Radio SBXY081 SBXY081 sits at $904, with the interquartile range running from $904 to $904. That flat range is a direct reflection of a sample size of one verified US comp, not a signal that the market is unusually stable. The comp carries a green verification status, meaning the underlying transaction data passed Tonbo's sourcing filters and represents a real completed sale rather than a listed ask. Buyers should treat $904 as a reasonable reference point while recognizing that a single data point cannot fully characterize the US market. As more comps accumulate, that spread will widen and sharpen into a more reliable benchmark. For a model with active JDM supply, the US comp thinness is worth noting before drawing firm conclusions about value.

Active JDM Listings

Japanese inventory for the SBXY081 is active right now. Six listings appeared on Yahoo Shopping within a single day on May 30, spanning a meaningful price range and several condition grades. That volume suggests this is not a scarce model in Japan, which matters when evaluating whether patient sourcing could yield a better entry price than the current US comp implies.

• ¥173,200 on Yahoo Shopping, listed in excellent condition
• ¥132,000 on Yahoo Shopping, condition listed as unknown (multiple listings at this price point)
• ¥109,780 on Yahoo Shopping, listed in good condition
• Price spread across active listings runs from roughly ¥109,780 to ¥173,200
• Four of the six listings carry unknown condition grades, which is a material consideration for buyers evaluating buy SBXY081 Japan options

The clustering of listings at ¥132,000 may reflect retailer pricing rather than organic secondary market activity, which would place the good-condition unit at ¥109,780 as the more interesting data point from an arbitrage standpoint.

Recent Alert History

No strict or opportunity alerts have fired for the Seiko Astron NEXTER Solar Radio SBXY081 in the past 90 days. That is an honest read of the signal history, not a gap in coverage. The absence of alerts means no Japanese listings have crossed Tonbo's pricing thresholds during that window, either because the JDM prices have held above alert trigger levels or because the US comp baseline is too thin to generate reliable differential signals. Buyers watching this reference can review the broader Tonbo signals feed to see how comparable Astron references are behaving in the meantime.

Japan vs. US Price Gap

The gap between JDM list prices and the US comp is partially a function of the SBXY081 being a Japan-domestic model with limited English-language retail exposure, which keeps US supply thin and secondary prices elevated relative to what patient buyers can access directly through Japanese platforms. At ¥109,780 for a good-condition unit, the landed cost after proxy service fees and shipping would need careful calculation against the $904 US reference to determine whether a real spread exists. The main risk factor here is condition variance. Four of the six current listings carry unknown condition grades, and without clear disclosure, buyers absorbing that uncertainty are taking on meaningful downside that the nominal price gap may not cover. Tracking active JDM deals over time gives a clearer picture of where condition-verified units typically price out.
