Citizen Attesa AT8186 (AT8186-51L, AT8186): Current Prices, JDM Listings, Market Analysis
The Citizen Attesa AT8186 is a JDM-market solar radio-controlled dress watch from Citizen's flagship Attesa line, tracked here under references AT8186-51L and AT8186. Tonbo monitors it because the US-Japan price gap creates periodic arbitrage windows, and the model surfaces regularly enough on Japanese platforms to make sourcing practical. At a current US median of $735, it sits in a tier where gross margin can be meaningful when the right Japan listing appears. Comp volume is limited, so that figure should be read as directional rather than definitive.
Current US Market Value
The AT8186-51L price in the US currently sits at a median of $735, with a middle-50% range running from $600 to $880. That spread of roughly $280 between the 25th and 75th percentile is wide relative to the median, which tells you condition and channel are doing a lot of work here. The underlying sample size is six verified transactions, flagged at 🟡 Limited comps quality. That means the median is a reasonable starting reference point, but it can shift meaningfully with a handful of additional data points. Treat the $600 to $880 range as the realistic trading band for now rather than anchoring too hard to any single figure.
Active JDM Listings
Japan listings for the AT8186 have been active in the past two weeks, with six separate postings appearing on Yahoo Shop storefronts on May 30. Pricing clusters at two levels, which suggests multiple dealers are holding inventory at structured price points. Condition details were not available on these listings from public data, which is a routine limitation with JDM storefront pulls.
- ¥52,800 on Yahoo Shop (May 30) , notably below the cluster, potentially representing a different condition tier or configuration
- ¥107,800 on Yahoo Shop (May 30) , appears twice, suggesting at least two units at this level
- ¥123,200 on Yahoo Shop (May 30) , appears three times, the most common ask price in this batch
- Listings are concentrated in Yahoo Shop storefronts rather than auction format
- No auction-format listings surfaced in this window, which limits downside price discovery from Japan
Recent Alert History
Four opportunity-tier alerts fired on May 25, all within the same sourcing window. Three of those landed at strong margins. Two units came in at landed costs of $457 and $459 respectively against a US median of $735, producing approximately 38% gross margin on each. A third landed at $513 for a 30% gross margin. The fourth unit in that batch landed at $880, which was above the US median and logged at negative 20% gross margin , a reminder that not every unit from the same sourcing event prices the same way. No strict-tier alerts have fired in the past 90 days. The signal pattern here is episodic rather than continuous, meaning the model goes quiet and then surfaces a cluster of opportunities. If you want to catch the next one, passive monitoring through Tonbo's signal feed is the most reliable method.
Japan vs. US Price Gap
The AT8186-51L for sale in Japan can land materially below US market value because the model has limited visibility among US buyers relative to globally distributed Citizen references, and Japanese dealers price to local demand. When Yahoo Shop storefront prices compress toward ¥52,800 to ¥107,800 and the dollar is reasonably strong, landed costs can fall well inside the US p25 floor of $600. The main friction on execution is condition variance , JDM storefront listings frequently lack detailed photographs, and box-and-papers status is inconsistent. The limited comp base (six US transactions) also means one bad resale outcome has outsized weight on your realized margin. Anyone looking to buy AT8186-51L from Japan should factor in a conservative condition discount until they can verify the piece.
