Citizen Promaster Marine Titanium BJ7110-89E (BJ7110-89E, BJ7110). Current Prices, JDM Listings, Market Analysis

The Citizen Promaster Marine Titanium BJ7110-89E is a dive-oriented JDM release from Citizen's Promaster line, built around the brand's reputation for lightweight titanium construction and professional-grade water resistance. It carries reference numbers BJ7110-89E and BJ7110, and sits in the segment of tool watches that hold steady collector interest without chasing hype. Tonbo tracks this model because it surfaces regularly in Japanese secondary markets at prices that can undercut US retail, and understanding that gap requires consistent data. Right now the US median sits at $380, though the sample behind that figure is thin enough to treat with some caution.

Current US Market Value

The current US median for the BJ7110-89E price is $380, with the middle half of transactions falling between $320 and $460. That spread is wider than you'd want for high-confidence sourcing decisions, and the reason is straightforward: this analysis is built on a sample size of four comparable sales. Comp quality is rated 🟡 Limited comps, which means the median is a reasonable directional signal but not a precise anchor. If you're evaluating a specific piece, condition and completeness will move the needle more than the market average does at this sample depth. Check back as the dataset grows, because thin comps on a model like this can shift meaningfully with just a few additional data points.

Active JDM Listings

Japanese market activity on the BJ7110-89E for sale has been light over the past two weeks, with one listing surfacing in the most recent 14-day window. That single appearance is worth noting for what it tells you about pricing floor and condition variance in the current market.

• Jun 15: Listed at ¥35,800 on Yahoo Flea Market, described as a little damaged and dirty
• At a mid-June exchange rate, ¥35,800 translates to roughly $230 to $245 USD before fees and shipping
• The condition disclosure is honest by Japanese platform standards, which typically means visible cosmetic wear rather than functional issues, but verification matters
• No box-and-papers listings appeared in this window, which is common for workhorse tool watches that see actual use
• Platform coverage is currently limited to Yahoo Flea Market. No Mercari or dealer listings were flagged in this cycle

Recent Alert History

No strict or opportunity alerts have fired on the Citizen Promaster Marine Titanium BJ7110-89E in the past 90 days. That absence reflects two things working together: listing volume in Japan has been low, and the comp base on the US side is too thin to generate high-confidence signal triggers. It does not mean the model is overpriced or unattractive. It means the data hasn't yet produced a moment where a Japan listing price was unambiguously strong relative to a reliable US benchmark.

Japan vs. US Price Gap

The ¥35,800 listing from mid-June, even after typical proxy fees and international shipping costs of $40 to $70, lands well below the US median of $380, which is the pattern Tonbo is built to surface. Titanium Promaster models tend to trade at a discount in Japan relative to their US secondary market value because domestic supply is higher and collector competition for tool watches in this tier is lower there than it is among US buyers seeking JDM exclusives. The primary risk here is condition variance: that single recent listing was explicitly flagged as damaged and dirty, and with only four US comps to reference, there's limited data on how much a non-pristine example actually discounts in the American market. Anyone looking to buy BJ7110-89E Japan should weight condition disclosure heavily and factor in the usual sourcing risks around authentication and return options when using proxy services.
