Citizen Promaster Mariner Black (NY0086). Current Prices, JDM Listings, Market Analysis
The Citizen Promaster Mariner Black is a dive-oriented automatic from Citizen's JDM-focused Promaster lineup, tracked here under reference NY0086. It surfaces regularly in both the Japanese secondary market and US resale channels, making it a useful model to watch for cross-border arbitrage. At a current US median of $205, it sits in a price band where small condition differences matter more than usual. Tonbo tracks this model because the Japan-to-US price gap creates periodic buying windows worth monitoring.
Current US Market Value
Based on verified eBay comps, the Citizen Promaster Mariner Black NY0086 is currently trading at a US median of $205. The interquartile range runs from $185 at the 25th percentile to $243 at the 75th, giving a spread of roughly $58 across typical transactions. That spread is meaningful on a $200 watch. The sample size of 16 comps is workable for directional pricing but not large enough to smooth out outliers entirely, so individual condition grades can move a specific listing outside this range in either direction. The comp quality is rated 🟢 Verified, meaning these are confirmed sold listings rather than ask prices, which makes the NY0086 price data here more reliable than models tracked on thinner data sets. If you are researching NY0086 for sale options, this range gives you a grounded baseline before you start comparing listings.
Active JDM Listings
Japan is showing consistent supply for this model right now. A cluster of listings appeared on June 11, spread across Yahoo Flea Market and multiple Yahoo Shop storefronts, with prices ranging from ¥29,800 on the low end to ¥59,800 at the top. The Yahoo Shop entries tend to carry some degree of retailer markup and occasionally reflect new or near-new inventory, while the flea market listing at ¥29,800 is the more aggressive price point. At current exchange rates, several of these land below the US median after accounting for proxy fees and shipping, though the condition mix is not uniform.
- ¥29,800 on Yahoo Flea Market (listed as new)
- ¥37,620 on Yahoo Shop (condition unknown)
- ¥36,650 on Yahoo Shop (condition unknown)
- ¥38,030 on Yahoo Shop (condition unknown)
- ¥41,030 on Yahoo Shop (condition unknown)
The concentration of listings on a single day suggests either a retailer refresh or aggregated sourcing. Either way, supply looks healthy for anyone looking to buy NY0086 from Japan at the moment.
Recent Alert History
No strict buy alerts or opportunity signals have fired for the NY0086 in the past 90 days. That is not a red flag, it simply means no individual listing has cleared Tonbo's threshold criteria for a verified underpriced comp or a notable arbitrage gap during that window. Models with lower transaction volume and mid-range pricing sometimes go through quiet periods where listings are priced at or near fair value rather than at actionable discounts. Checking the Tonbo signals feed directly will show you the current status and let you compare alert activity across similar models.
Japan vs. US Price Gap
The JDM supply visible right now in Japan is largely priced in the ¥29,800 to ¥41,030 range, which at roughly 155 yen to the dollar translates to approximately $192 to $265 before proxy and shipping costs. After those are factored in, the gap versus the US median narrows significantly and, at the higher Yahoo Shop prices, disappears or inverts. The more competitive entry point is the flea market listing, where a new-condition unit at ¥29,800 could still represent a modest opportunity depending on import costs and the buyer's landed cost math.
The primary risk factor flagged for this model is condition variance on the black dial. Black dials on dive watches show scratches and wear differently than lighter dials, and condition descriptions in Japanese secondary listings are not always granular enough to assess dial condition remotely. That makes photos essential and introduces uncertainty that the comp range alone cannot resolve. You can review how Tonbo evaluates condition risk across JDM models on the deals methodology page.
