Seiko Presage Classic Series Dark Green 40mm SARX123 (SARX123). Current Prices, JDM Listings, Market Analysis
The Seiko Presage Classic Series Dark Green 40mm SARX123 is a Japan domestic market release from Seiko's Presage lineup, a range known for its enamel dials, dress-oriented proportions, and positioning above the standard Seiko catalog. The SARX123 specifically draws attention for its dark green dial treatment, which has found consistent demand among collectors who track JDM-exclusive colorways unavailable through Seiko's international distribution. Tonbo tracks this reference because the Japan-to-US price gap can create real purchasing opportunities when sourced carefully. At present, the US market shows a narrow data footprint, so buyers and sellers alike should weigh that context before transacting.
Current US Market Value
The current US median for the SARX123 price sits at $738, drawn from verified eBay comp data flagged at 🟢 Verified quality. The honest caveat here is that the sample size is one transaction, which means the $738 figure reflects a single data point rather than a trend. The interquartile range runs $738 to $738 for the same reason. This is a watch where the US secondary market is thin enough that one outlier sale in either direction could shift the picture materially. Until more comps accumulate, treat the $738 figure as a directional reference rather than a settled market price. If you are researching SARX123 for sale in the US, that number is the best verified anchor available right now, but confirmation from additional sales would strengthen confidence considerably.
Active JDM Listings
Japan is showing meaningful supply on the SARX123 right now. As of May 30, six listings appeared on Yahoo Shopping, ranging from ¥93,280 at the low end to ¥132,000 across five separate listings at the higher tier. The clustering at ¥132,000 suggests that is where Japanese sellers have anchored the retail or near-retail ask, while the single ¥93,280 listing may represent a discounted or used condition unit. Condition grades on the lower listing are rated "good," while the ¥132,000 listings carry unknown condition designations. Anyone looking to buy SARX123 in Japan should treat the condition unknowns as a due-diligence item before committing.
- ¥93,280 on Yahoo Shopping, condition rated good (May 30)
- ¥132,000 on Yahoo Shopping, condition unknown, five separate listings (May 30)
- Price spread between lowest and highest ask is approximately ¥38,720
- All active listings sourced from Yahoo Shopping platform
- No listings observed outside Yahoo Shopping in the current 14-day window
Recent Alert History
No strict buy alerts or opportunity signals have fired for the SARX123 over the past 90 days. That absence is worth naming plainly. It does not mean the watch is uninteresting, but it does mean the automated thresholds Tonbo uses for flagging high-confidence arbitrage moments have not been met in that window. Buyers who want to act on the current JDM supply should do their own spread calculation rather than relying on a triggered alert as validation. You can track live signal activity for this reference and others through Tonbo's signals dashboard.
Japan vs. US Price Gap
At current exchange rates, the ¥93,280 low listing converts to roughly $620 to $640 USD depending on the rate used, which sits meaningfully below the $738 US median. The five listings at ¥132,000 convert closer to $870 to $890, which would invert the spread and make US sourcing more competitive at that price point. The practical opportunity, if one exists, is concentrated in that single lower-priced listing, assuming condition holds up on inspection. The main risk factor for this model is what applies to most JDM sourcing at thin US comp volumes: condition variance and the difficulty of asserting a defensible resale price when only one US transaction anchors the market. Buyers should also factor in typical JDM acquisition costs including proxy fees, shipping, and potential import duties when modeling the actual landed cost.
