Seiko Prospex Speedtimer Solar Chrono White Panda SBDL085 (SBDL085, SSC813). Current Prices, JDM Listings, Market Analysis
The Seiko Prospex Speedtimer Solar Chrono White Panda SBDL085 is a JDM-market solar chronograph sold under the Prospex Speedtimer line, sharing its core DNA with the export-market SSC813. It moves consistently enough in both Japan and the US to generate regular arbitrage signals, which is why Tonbo tracks it. Right now the US median sits at $541 across a 135-transaction sample, and Japan is showing fresh listings well below that figure.
Current US Market Value
Based on 135 verified US eBay transactions, the SBDL085 price lands at a median of $541. The interquartile range runs from $450 at the 25th percentile to $599 at the 75th percentile, so there is meaningful spread depending on condition and whether a box and papers accompany the piece. A sample of 135 is solid for a JDM reference at this price tier and gives reasonable confidence in the median. Tonbo rates the comp quality 🟢 Verified comps, meaning the underlying transactions passed automated screening for outlier prices and non-watch listings before being included. Buyers researching SBDL085 price should treat $541 as the realistic center of the market, not a floor or ceiling.
Active JDM Listings
Six listings appeared on Japanese platforms on May 30 alone, spanning both curated shop inventory and flea-market sellers. The range is wide, which is typical when a model has both professional resellers and individual owners clearing stock at the same time. The lowest prices are coming from yahoo flea listings marked as new condition, which is worth noting for buyers considering buy SBDL085 Japan sourcing.
- ¥22,550 on Yahoo Shop (condition unspecified)
- ¥21,450 on Yahoo Shop (condition unspecified)

- ¥14,700 on Yahoo Flea Market (listed as new)
- ¥14,170 on Yahoo Flea Market (listed as new)

Recent Alert History
Four alerts fired across a four-day window in late May, a frequency that places this reference in Tonbo's active-tracking tier. Three of those alerts were classified as activity tier, with landed costs between $539 and $562 against a US median of $620 at the time of those alerts. One alert on May 24 reached the strict tier, with a landed cost of $472 and a 24% gross margin against that same $620 median figure. The fact that the US median in the current dataset reads $541 rather than $620 suggests the market has compressed somewhat since those alerts fired, so forward margins will be tighter than the alert history implies at face value.
Japan vs. US Price Gap
The SBDL085 is a JDM-exclusive reference, meaning it does not appear in Seiko's US retail channel under this number, and that supply gap historically supports a price premium stateside. When Japanese sellers list new or near-new stock on flea platforms to clear inventory quickly, the gap between acquisition cost and US resale value can be meaningful, though the current compression in US prices narrows the window compared to what the May alerts reflected. The main risk here is condition variance on flea market sourcing, since "new" on a Japanese flea platform can mean anything from factory-sealed to unworn but without original packaging, and that distinction matters when buyers in the US are pricing against the full range from $450 to $599. Deals with strong historical margins are catalogued in Tonbo's verified deals archive for reference.
