Citizen Attesa Eco-Drive Radio (2020-) (AT8181-63E, AT8181, Attesa). Current Prices, JDM Listings, Market Analysis
The Citizen Attesa Eco-Drive Radio is a solar-powered atomic timekeeping watch from Citizen's upper-tier Attesa line, produced from 2020 onward under reference AT8181-63E. It sits at the more accessible end of the Attesa range while still carrying the solar radio-controlled feature set that defines the lineup. Tonbo tracks this model because it moves with reasonable frequency across JDM platforms, and recent alert activity suggests enough price spread between Japan and the US to be worth monitoring. The current US median lands at $508, which positions it as a mid-range target for buyers sourcing from Japan.
Current US Market Value
The AT8181-63E price on the US secondary market currently sits at a median of $508, with the middle range of transactions falling between $491 and $611. It is worth being direct about the data here: this estimate is built on a sample size of three verified comps sourced from eBay, which means the figures are directionally useful but not statistically deep. Comp quality is rated 🟢 Verified comps, meaning these are confirmed sales rather than asking prices, so the numbers reflect what buyers are actually paying. Treat the median as a working benchmark rather than a firm floor. Anyone searching for AT8181-63E for sale in the US should expect pricing within that $491 to $611 band for examples in typical secondary-market condition, with outliers on either side depending on box, papers, and overall state.
Active JDM Listings
Japan is currently showing a wide spread of AT8181 listings, which is one of the more telling signals when evaluating whether a model is worth pursuing. As of late May, Mercari Japan and the main Japanese auction platform both have multiple active examples, ranging from deeply discounted to near-retail asking prices. That range alone tells you condition and seller expectations vary considerably. A few highlights from the past 14 days:
- ¥33,000 on Mercari (condition unknown) , the low end of current Japan supply
- ¥41,000 on the Japanese auction platform (condition unknown)
- ¥50,380 on the Japanese auction platform, listed in excellent condition
- ¥119,999 on Mercari , toward the upper range, likely reflecting box and papers or near-new status
- ¥146,800 on Mercari , the ceiling of current asking prices, possibly NOS or dealer-listed
The gap between ¥33,000 and ¥146,800 is significant. Buyers looking to buy AT8181-63E from Japan need to be selective. The lower-priced listings may represent real value or may reflect undisclosed wear. The ¥50,380 excellent-condition listing is the most transparently priced of the recent batch.
Recent Alert History
Alert activity over the past 90 days has been meaningful. Tonbo's system flagged four transactions at the activity tier, which tracks deals that cleared rather than strict or opportunity-level signals. The spread in outcomes across those four alerts illustrates how much execution and condition affect actual returns. One landed at $934 against a US median of $1,150, producing a 19% gross margin. Another came in at $266 landed against a $450 median, generating 41% gross margin. Two others came in at $520 and $486 respectively against a $450 median, both showing negative gross margin at the time they fired. The lesson from that pattern is straightforward: the AT8181-63E can work, but buying at the wrong price or in the wrong condition erases the spread quickly. Consistent tracking of live signals matters more here than one-time opportunism.
Japan vs. US Price Gap
The US-Japan price gap on the Citizen Attesa Eco-Drive Radio (2020-) exists primarily because Japanese domestic supply is deep and fragmented across multiple platforms, while US buyers who want this specific reference have fewer places to find it at volume. That supply asymmetry creates periodic opportunities, particularly when Japanese sellers price to move rather than to maximize. The main risk on this model is condition variance compounded by thin US comps. With only three verified US sales in the dataset, a single below-average condition piece can distort your read on what the market will actually pay. Anyone evaluating current deal flow on this reference should weight the ¥50,380 excellent-condition listing differently from the unknown-condition examples at ¥33,000 to ¥41,000, and factor landed cost carefully before committing.
