Orient Open Heart (2018-) (RA-AG0017S10B). Current Prices, JDM Listings, Market Analysis
The Orient Open Heart is a dress-casual automatic from Orient's modern lineup, distinguished by its skeletonized dial aperture that exposes the movement below. The RA-AG0017S10B reference is among the more visually accessible open-heart designs in the sub-$300 bracket, drawing consistent interest from buyers looking for mechanical character at an entry price point. Tonbo tracks this model because JDM supply occasionally creates pricing gaps worth monitoring. The current US market sits at a median of $200, though the data behind that figure carries meaningful uncertainty.
Current US Market Value
The US median for the Orient Open Heart (2018-) RA-AG0017S10B is currently $200, with the middle half of observed transactions falling between $150 and $280. That spread is wider than ideal, which reflects the thinness of the underlying dataset. This price estimate is drawn from a sample size of five transactions and is sourced from a category-level estimate rather than model-specific sale records. The comp quality rating is 🟠Estimate only, which means any RA-AG0017S10B price you see here should be treated as a directional benchmark rather than a precise market clearing figure. Buyers researching RA-AG0017S10B for sale in the US should weight recent individual listings heavily alongside this estimate.
Active JDM Listings
Japanese marketplace activity for this model in the past two weeks shows a notable concentration of listings on Yahoo Shopping, with prices spanning a wide range. Several listings are clustering around the ¥298,000 to ¥358,000 band, which sits well above what the US median would imply even after conversion and fees. A few lower-priced outliers appear as well. Condition grades are not available for any of these listings in the current data pull, which limits direct comparison.
- ¥158,550 on Yahoo Shopping (lowest observed, condition unknown)
- ¥238,460 on Yahoo Shopping (mid-range outlier)
- ¥298,450 on Yahoo Shopping (near the cluster floor)
- ¥333,120 on Yahoo Shopping (two listings at this price point)
- ¥358,040 on Yahoo Shopping (current ceiling)
The concentration of listings at similar price points on the same platform suggests either a single seller with multiple units or coordinated retail pricing rather than organic secondhand supply. That distinction matters when evaluating whether buy RA-AG0017S10B Japan searches are likely to surface genuine arbitrage opportunities or simply retail inventory.
Recent Alert History
No strict-buy or opportunity-tier alerts have fired for the Orient Open Heart (2018-) RA-AG0017S10B in the past 90 days. This can mean a few different things. The JDM listings appearing right now are priced above the threshold where the model would represent a clear arb opportunity at current US values. It may also reflect the thin comp base making it harder for the alert engine to validate a signal with confidence. Either way, buyers watching this reference should not interpret the absence of alerts as absence of activity. The Japan-side listings are live; the economics just haven't aligned recently.

Japan vs. US Price Gap
At current exchange rates, the lower end of the Japanese listings translates to roughly $1,000 or more after conversion, which is far above the US median of $200. That gap almost certainly reflects a mismatch between what these Yahoo Shopping listings represent and where the actual gray market trades. The listed Japanese prices may reflect new or near-new retail positioning, while US comparables are tracking older or pre-owned units at lower price points. The primary risk here is comp thinness: with only five US data points underlying the $200 median, a single outlier transaction in either direction can shift the benchmark meaningfully. Anyone evaluating this model for resale or personal import should build in a wider margin of error than they would on a watch with deeper transaction history.
