Citizen Series 8 880 Hi-Beat (NA1004, 880 hi-beat). Current Prices, JDM Listings, Market Analysis
The Citizen Series 8 880 Hi-Beat is a JDM-market mechanical watch carrying the NA1004 reference and powered by a hi-beat caliber 0950, a movement specification that places it firmly in the upper tier of Citizen's domestic lineup. Tonbo tracks this model because it sits at a price point where Japanese domestic availability and US resale demand can create meaningful spreads worth monitoring. The current US median of $634 positions it as an attainable but legitimate mechanical piece, not a throwaway grade. With verified comps and visible Japan inventory, it's a model worth understanding before you buy.
Current US Market Value
The NA1004 price on the US secondary market sits at a median of $634, with the middle 50% of recent transactions ranging from $598 to $777. That spread of roughly $179 between the 25th and 75th percentile tells you condition and configuration variance exist but are not extreme. The sample size is eight transactions, which is thin enough to treat directionally rather than as a high-confidence benchmark. Importantly, the comps underpinning these figures carry a verified status, meaning they come from confirmed eBay sale data rather than asking prices or estimates. For a JDM model with limited US awareness, verified comps at even a small sample size carry more weight than a larger pool of unvalidated listings. If you're researching NA1004 for sale options in the US, the $598 floor represents a realistic entry point on a cleaner example when the market is soft.
Active JDM Listings
Japan is showing active supply right now. As of late May, multiple listings appeared across Mercari Japan and Yahoo Auctions Japan within a 24-hour window, which suggests this is not a scarce model in its home market. Pricing varies meaningfully depending on condition disclosure and platform, from under ¥100,000 to over ¥200,000. That range is wider than you'd expect from a homogeneous pool, pointing to real differences in listed condition and possibly configuration. Anyone looking to buy NA1004 from Japan should expect to work through that variance carefully.
- May 24, Mercari Japan: ¥133,500, listed as excellent condition
- May 24, Mercari Japan: ¥140,000, listed as excellent condition
- May 24, Mercari Japan: ¥125,000, condition unknown
- May 24, Yahoo Auctions Japan: ¥99,000, condition unknown
- May 24, Yahoo Auctions Japan: ¥209,000, condition unknown
The ¥99,000 listings are the ones worth scrutinizing first. At current exchange rates, those translate to a price level where the US-to-Japan arbitrage math can work, assuming condition holds. The ¥209,000 listing sits at a premium that would compress or eliminate any margin after fees, shipping, and import considerations.
Recent Alert History
No strict-buy or opportunity-tier alerts have fired for the Citizen Series 8 880 Hi-Beat in the past 90 days. That absence doesn't mean the model is uninteresting. It means the Japan listings tracked during that period didn't clear the thresholds Tonbo uses to flag genuine price dislocations. Given that Japan supply appears active, the market has likely been fairly priced relative to US comps rather than offering the kind of one-sided gaps the alert system is calibrated to surface. Subscribers watching this model through Tonbo's signal feed would receive a notification the moment that changes.
Japan vs. US Price Gap
The US-Japan price gap on the NA1004 is driven by the typical JDM dynamic: a watch that was never officially sold in the US carries name-recognition friction that suppresses domestic buyer competition, while Japanese supply remains steady because it was a standard domestic release. When the yen is weak and JP listings appear at the lower end of the observed range, the landed cost after proxy fees and shipping can sit comfortably below the US p25 of $598. The main risk factor to account for is the hi-beat caliber 0950. Hi-beat movements run at elevated beat rates that place more stress on components over time, and service histories on grey-market JDM pieces are often undocumented. Buying from a listing with unknown condition and no service records on a hi-beat movement is a risk worth pricing in explicitly, not ignoring.
