Orient Star Sun & Moon RK-AT0006A (RK-AT0006A, RE-AT0006A). Current Prices, JDM Listings, Market Analysis

The Orient Star Sun & Moon RK-AT0006A is a JDM-market watch from Orient's premium Star line, tracked here under both reference numbers RK-AT0006A and RE-AT0006A, which commonly appear interchangeably across Japanese and international listings. The Sun & Moon complication has built a steady following among collectors who want mechanical depth at an accessible price point, and the RK-AT0006A sits at a range where JDM sourcing can offer genuine value over domestic retail. Tonbo tracks this model because the US-Japan price gap is real but variable, and buyers benefit from knowing where the market actually sits before committing. Current US median pricing places this watch firmly in the $300 range, making RK-AT0006A price transparency genuinely useful for anyone considering a purchase.

Current US Market Value

The current US median for the Orient Star Sun & Moon RK-AT0006A sits at $320, with the interquartile range running from $250 at the low end to $450 at the upper end. That $200 spread is wide relative to the median, which tells you condition and seller type are doing significant work here. Watches toward the bottom of that range are typically pre-owned pieces from private sellers or auction closings, while the upper end reflects dealer-priced examples or near-new condition units. It is worth noting that the comp pool for this model is limited, and Tonbo rates the data quality as 🟡 Limited comps, meaning the median is directionally useful but should not be treated as a high-confidence anchor. As more transaction data accumulates, that picture will sharpen. For now, the $320 figure is a reasonable baseline for calibrating what you see listed, not a precise floor or ceiling.

Active JDM Listings

Japanese market activity for the RK-AT0006A is light but present. A single listing appeared in the past 14 days, priced at ¥64,240 on Yahoo Shopping Japan. At current exchange rates that translates to roughly $415 to $430 depending on conversion costs, which places it toward the upper end of the US interquartile range before any shipping or import fees are factored in. That pricing does not immediately suggest a discount opportunity, but the condition of this specific listing is unknown, and Yahoo Shop listings in Japan often carry a degree of seller accountability that private auction listings do not.

• May 24 listing on Yahoo Shopping Japan at ¥64,240
• Condition grade for the active listing is unconfirmed
• Only one listing observed in the past 14-day window, indicating thin inventory
• No Mercari, Rakuten, or Yahoo Auctions Japan listings recorded in the same period
• Thin JDM supply can mean pricing power sits with sellers, which compresses arbitrage potential

Recent Alert History

No strict or opportunity alerts have fired for the Orient Star Sun & Moon RK-AT0006A in the past 90 days. This means Tonbo's signal engine has not detected a listing that clears the threshold for a meaningful undervaluation relative to the US market benchmark. The absence of alerts is not a red flag on the watch itself. It reflects the combination of thin JDM supply and a comp pool that does not yet produce tight enough bounds to generate high-confidence buy signals. Collectors watching this reference can track live signal activity for similar Orient Star models through the Tonbo signals page, which updates in real time as new listings come in across Japanese platforms.

Japan vs. US Price Gap

The US-Japan gap for JDM Orient Star models generally exists because the domestic Japanese market has more supply and lower brand premiums than the US, where Orient Star distribution is more limited and buyers often pay a convenience premium through authorized or grey-market dealers. For the RK-AT0006A specifically, the current single active listing at ¥64,240 does not represent an obvious discount once sourcing costs are included, but that picture can shift quickly if additional listings appear at lower ask prices. The most honest risk to flag here is comp thinness. With a limited sample size and 🟡-rated data quality, any individual transaction you make carries more model-specific uncertainty than it would for a watch with dozens of documented comps. Cross-reference any purchase against recent sold data, not just asking prices, and check the Tonbo deals feed for confirmed transaction context when it becomes available for this reference.
