Citizen Attesa GPS (2022-) (AT8240-55E, AT8240, GPS Attesa). Current Prices, JDM Listings, Market Analysis
The Citizen Attesa GPS line represents one of Citizen's most technically serious solar GPS timekeeping platforms, built for the Japanese domestic market and carrying reference numbers including the AT8240-55E. Tonbo tracks this model because it regularly surfaces at favorable entry points in Japan while carrying meaningful value on the US grey market. The current US median sits at $809, and recent alert data suggests the spread between landed cost and US asking price has been wide enough to flag multiple opportunity-tier signals in a short window. For buyers researching AT8240-55E price and availability, the picture right now is reasonably active on both sides of the Pacific.
Current US Market Value
Based on Chrono24 asking prices, the Citizen Attesa GPS AT8240-55E currently sits at a US median of $809, with the middle 50% of listings running between $645 and $811. That's a fairly compressed interquartile range, suggesting reasonable price consistency among the listings that do exist. The important caveat here is sample size. This analysis draws from 7 comparable listings, which Tonbo flags as limited comp quality (🟡). That means the median is a directionally useful number but shouldn't be treated with the same confidence you'd apply to a model with 40 or 50 active comps. Anyone tracking AT8240-55E price over time should check back as liquidity builds. Thin comp pools can shift quickly when a few listings move or new ones appear.
Active JDM Listings
Japanese marketplace activity for the AT8240 has been notably clustered, with several listings appearing on the same date across both flea market and shop platforms. Prices span a fairly wide band depending on condition, which is typical for a model that moves through both individual sellers and established shops. Here's a snapshot of what's live as of the most recent pull:
- ¥93,000 on Yahoo Flea Market, listed as new condition
- ¥93,280 on Yahoo Shop, listed as excellent condition
- ¥87,780 on Yahoo Shop, listed as used condition
- ¥82,280 on Yahoo Shop, listed as good condition
- ¥65,780 on Yahoo Shop, listed as good condition (also a second listing at the same price with condition listed as unknown)
The spread from ¥65,780 to ¥93,280 across listings on the same day is meaningful. Entry-level good-condition pieces are sitting roughly 30% below the top of the range, which matters when you're modeling landed cost against a US median. For anyone looking to buy AT8240-55E from Japan, the lower-end shop listings represent the more interesting starting point for value analysis.
Recent Alert History
The Citizen Attesa GPS AT8240-55E has been generating consistent opportunity-tier alerts through Tonbo's signal system. Four alerts fired within a single day in mid-May, all at the opportunity tier, with landed costs ranging from $669 to $726. At that time, the system was referencing a US median of $1,400, producing gross margin estimates between 48% and 52%. It's worth noting that the current page shows a US median of $809 rather than $1,400, which likely reflects an update to the comp pool or methodology. The alert history should be read as a record of signal conditions at the time they fired, not a projection of current margins. What the pattern does confirm is that this model has been surfacing at competitive Japan prices with enough regularity to trigger repeated flags in a short period.

Japan vs. US Price Gap
The US-Japan price gap on the AT8240-55E is driven by a combination of factors that are fairly standard for JDM Citizen pieces at this tier. The Attesa GPS line doesn't see heavy grey market promotion in Western markets, so US inventory stays thin and asking prices remain elevated relative to what shops and private sellers in Japan are moving units for. Sourcing cost, shipping, and any import handling narrow the raw spread, but the gap has been wide enough to support opportunity-tier classifications at landed costs well below current US asking prices. The primary risk factors here are the ones common to most JDM sourcing. Condition descriptions vary between sellers and platforms, the comp pool on the US side is thin enough that a few outlier listings can distort the median, and currency movement affects landed cost in ways that aren't always visible until the deal closes.
