Citizen Promaster Mariner (NY0085, Mariner). Current Prices, JDM Listings, Market Analysis
The Citizen Promaster Mariner is a mechanical diver from Citizen's sport-oriented Promaster lineup, tracked here under reference NY0085. It sits in an accessible price band that draws consistent attention from buyers who want a legitimate mechanical dive watch without the premium attached to European alternatives. The US market currently places this model just above the $230 range, which makes NY0085 price comparisons against Japanese listings a reasonable exercise. Tonbo tracks it because JDM supply occasionally surfaces condition-graded examples that undercut the US median by a meaningful margin.
Current US Market Value
Based on 15 verified US sale comps pulled from eBay, the Citizen Promaster Mariner NY0085 carries a current median of $232. The interquartile spread runs from $197 at the 25th percentile to $274 at the 75th percentile, giving buyers a realistic window of about $77 between a good deal and a fair-market transaction. The sample size of 15 is workable for directional pricing but sits on the thinner side, so individual condition factors carry more weight here than they would on a model with 50-plus comps. Comp quality is rated 🟢 Verified, meaning the underlying sales data has passed Tonbo's review process rather than relying on unfiltered noise.
Active JDM Listings
Japanese listings captured on June 11 show a wide spread in both platform type and asking price, which is worth paying attention to before you move on any single listing. Yahoo Flea Market is carrying most of the current supply, and the range across those listings is striking enough to warrant careful condition review on each one. The ¥39,700 Yahoo Shop listing is the clear outlier on the low end and may reflect a specific variant, condition issue, or aggressive pricing from a dealer moving inventory.
- ¥39,700 on Yahoo Shop, condition unspecified
- ¥49,800 on Yahoo Flea Market, no noticeable scratches or stains
- ¥160,000 on Yahoo Flea Market, no noticeable scratches or stains (two separate listings at this price)
- ¥109,800 on Yahoo Flea Market, listed as new
- ¥268,000 on Yahoo Flea Market, no noticeable scratches or stains
The ¥160,000 and ¥268,000 listings in particular suggest sellers may be pricing for a different variant or configuration than the base NY0085 reference. Anyone looking at NY0085 for sale in Japan should treat the upper listings with some skepticism until the specific reference is confirmed.
Recent Alert History
No strict buy alerts or opportunity signals have fired for the Citizen Promaster Mariner in the past 90 days. That is an honest read of the data rather than a gap in coverage. It means no individual listing crossed Tonbo's thresholds for a verified below-market transaction during that window. For a model at this price point, alerts tend to be infrequent by nature since the absolute dollar spread between a good and a great deal is narrower than on higher-value references.

Japan vs. US Price Gap
At current exchange rates, the ¥49,800 clean-condition listing converts to roughly $320 to $340 depending on sourcing fees, which actually puts it above the US median rather than below it. The lower ¥39,700 shop listing is the only one that, after fees and shipping, might land near the US p25 of $197, and that one comes with unknown condition. The core risk factor flagged for this model is condition variance on what Tonbo categorizes as an updated mechanical diver, meaning different production runs or configurations can carry meaningfully different values, and buyers should confirm exact reference alignment before treating any Japanese listing as a direct comp to US sales data. The deals feed filters for listings where the gap is confirmed to be in the buyer's favor.
