Citizen Series 8 Slim 39mm Green NB6080-51W (NB6080-51W, NB6080). Current Prices, JDM Listings, Market Analysis

The Citizen Series 8 Slim 39mm Green NB6080-51W is a JDM-market dress watch that attracts buyers in the US primarily because it does not appear in standard retail channels stateside. Tonbo tracks it because the Japan-to-US price gap creates periodic sourcing windows worth watching. At the current US median of $1,100, the model sits in a price tier where condition and sourcing discipline matter considerably. This page reflects live market data and is updated as new listings and transactions surface.

Current US Market Value

The current US median for the NB6080-51W price sits at $1,100, with the middle 50% of transactions falling between $1,071 and $1,249. It is worth noting that this estimate draws from a sample size of three verified US comparables, which is thin. The comps are rated 🟢 Verified, sourced via eBay scrape, meaning they reflect actual completed sales rather than asking prices, but three data points do not establish a deep or stable price floor. Treat the range as directional rather than definitive until more transactions accumulate. If you are researching NB6080-51W for sale in the US secondary market, that $1,071 to $1,249 band is the honest starting reference.

Active JDM Listings

Japan is showing solid listing density for the NB6080-51W right now. Multiple sellers posted simultaneously on May 30, spanning Yahoo Shopping, Yahoo Flea Market, and a Japanese marketplace platform, with prices ranging from roughly ¥125,800 to ¥163,290. The spread across condition grades is notable and worth unpacking before committing to any purchase.

• ¥125,800 on Yahoo Flea Market, listed as new condition
• ¥159,500 appearing across multiple Yahoo Shopping storefronts, condition listed as unknown
• ¥163,290 on a Japanese marketplace, graded as excellent condition
• Several Yahoo Shopping listings at identical price points suggest either a single seller using multiple storefronts or coordinated pricing among independent dealers

For anyone looking to buy NB6080-51W Japan, the ¥125,800 flea market listing at new condition is the standout value anchor, though flea market sourcing carries its own verification considerations.

Recent Alert History

Activity-tier alerts fired four times in a tight cluster around May 25. Each alert logged a landed cost of $1,160 against a US median of $1,280 at the time, producing a gross margin signal of approximately 9%. Activity-tier alerts are not the strongest signal type in the Tonbo system. They indicate that sourcing opportunities are appearing at a pace worth tracking, but the margins here are modest rather than exceptional. No strict or opportunity-tier alerts have fired in the past 90 days, which tells you that deep-discount entry points have not materialized recently. The 9% gross margin figure is a pre-fee, pre-risk estimate and does not account for import costs, platform fees, or condition-related price haircuts on the US sale side.

Japan vs. US Price Gap

The NB6080-51W is a Japan-domestic release, and limited US retail availability is the primary structural driver of the price gap between Japanese listings and US secondary market values. Buyers in the US who want this specific green dial variant have few alternatives to the grey market, which keeps secondary prices elevated relative to what Japanese sellers are willing to accept. The main risk factor here is consistent with typical JDM sourcing situations: condition variance combined with thin US comp data. With only three US comparables on record, a single outlier transaction can distort the median meaningfully, and a watch arriving in softer-than-expected condition can compress your realized sale price below the modeled range. Sourcing from sellers with detailed photos and clear condition grading is the most straightforward way to manage that exposure. You can review how Tonbo categorizes and scores these risks at the signals methodology page.
