Orient Star Mechanical Moon Phase RK-AM0005A (RK-AM0005A, RK-AM0005S). Current Prices, JDM Listings, Market Analysis

The Orient Star Mechanical Moon Phase RK-AM0005A is a JDM complication watch tracked under reference numbers RK-AM0005A and RK-AM0005S. It sits within Orient's premium Star line, a segment that consistently draws attention from collectors looking for mechanical moon phase complications at accessible price points. Tonbo Market tracks this model because it appears in Japanese listings at prices that can differ meaningfully from US market values. Current US median pricing sits at $750, though active JDM sourcing shows a wider band worth understanding before buying.

Current US Market Value

The Orient Star Mechanical Moon Phase RK-AM0005A price in the US currently sits at a median of $750, with the middle 50 percent of transactions ranging from $675 to $990. That spread is wider than typical for a single reference, which reflects the underlying data quality. Comp quality for this model is rated 🟡 Limited comps, meaning the sample size feeding these estimates is small and should be read as directional rather than precise. If you are evaluating an RK-AM0005A for sale at the high end of that range, condition documentation becomes especially important given how thin the comparable sales pool is. As more transactions flow through the market, these estimates will tighten.

Active JDM Listings

Japanese marketplace activity over the past 14 days shows two active listings, both appearing on Yahoo Shop. The price gap between them is notable and likely reflects condition differences, which is typical for this type of JDM sourcing. Here is what the current data shows:

• May 30 listing on Yahoo Shop (used condition): ¥88,880
• May 30 listing on Yahoo Shop (condition unlisted): ¥129,800
• The spread between the two listings is roughly ¥41,000, suggesting significant condition or completeness variation
• Both listings appeared on the same day, which may reflect routine restocking activity rather than unusual supply movement
• No listings from other Japanese platforms have appeared in this window

For those looking to buy RK-AM0005A from Japan, the ¥88,880 used listing is the more relevant data point for Japan vs. US market comparison, though condition details would need verification before drawing conclusions.

Recent Alert History

No strict or opportunity alerts have fired for the Orient Star Mechanical Moon Phase RK-AM0005A in the past 90 days. This means the model has not triggered any of Tonbo's threshold-based signals during that period, either because Japanese prices have not dropped far enough below US market levels to generate a clear opportunity, or because listing volume has been too low to create a confirmed signal. The absence of alerts is not a negative judgment on the model. It simply means the gap between JDM and US pricing has not crossed the thresholds that Tonbo's system uses to surface actionable deals. You can review how those thresholds work at tonbomarket.com/signals.

Japan vs. US Price Gap

The US-Japan price gap for the RK-AM0005A is driven by the usual JDM dynamics. This reference is not widely distributed through US retail channels, which creates natural friction between supply and demand on the American side and tends to push US prices above what Japanese domestic listings show. At the ¥88,880 used price point, after factoring in shipping, import duties, and payment platform fees, the math may still work in a buyer's favor relative to the US median, but the margin is not wide.

The main risk here is comp thinness. With limited comparable sales on the US side, there is genuine uncertainty about where a specific unit will actually clear. Condition variance between Japanese listings compounds this, since a used piece described vaguely carries more uncertainty than a box-and-papers example. Anyone sourcing this model should treat the $750 median as a rough anchor, not a guaranteed outcome, and verify condition details carefully before committing. Typical JDM sourcing risks around returns, language barriers, and seller reputation also apply.
