Tudor Black Bay 36 (2018-) (M79580B, M79580B-0001, BB36). Current Prices, JDM Listings, Market Analysis
The Tudor Black Bay 36 in reference M79580B sits at the more accessible end of the Black Bay family, offering the same vintage-inflected aesthetic as its larger siblings in a 36mm package that has found a dedicated following among collectors who prefer a smaller case diameter. Tonbo tracks this model because its JDM presence creates periodic pricing gaps worth monitoring, particularly for buyers who understand how condition grading and box-and-papers status affect realized value. At a current US median of $2,132, the M79580B occupies a competitive middle ground in the pre-owned Tudor market. With limited comparable sales data on hand, this page will be updated as market depth improves.
Current US Market Value
The Tudor Black Bay 36 M79580B price currently sits at a US median of $2,132, based on a sample of 12 transactions drawn from Chrono24 as the primary comp source. The interquartile range runs from $1,899 at the 25th percentile to $2,426 at the 75th percentile, giving a spread of roughly $527 across the middle half of the market. That spread is meaningful relative to the median and reflects the degree to which condition, dial variants, and inclusion of original box and papers move the needle on this reference. It is worth flagging that 12 comps is a thin dataset. Tonbo rates this data quality as limited, which means the median should be treated as a directional benchmark rather than a precise market-clearing price. As additional M79580B for sale listings accumulate, confidence in these figures will improve.
Active JDM Listings
Japanese market activity for the Black Bay 36 has been quiet over the tracked 14-day window, with one listing surfacing. That single data point is not enough to draw firm conclusions about JDM supply levels, but it does confirm the model moves through Japanese platforms and is worth watching for buyers interested in how to buy M79580B Japan listings at favorable rates.
- May 21: One listing appeared on a Japanese platform at ¥14,330 (condition grade unknown)

Recent Alert History
No strict or opportunity alerts have fired for the Tudor Black Bay 36 M79580B in the past 90 days. This does not mean the model lacks arbitrage potential, but it does indicate that no listing has cleared Tonbo's threshold filters for price anomaly or deal quality during this period. Thin JDM supply and limited comp depth are the most likely explanations. Collectors tracking this reference should consider setting a personal alert rather than waiting for a signal to appear organically, given how infrequently this model surfaces in monitored channels.

Japan vs. US Price Gap
The gap between JDM listing prices and US market values for the Black Bay 36 can be meaningful when a well-graded example surfaces in Japan, particularly because Japanese sellers often price to domestic demand rather than tracking US Chrono24 comps in real time. The M79580B benefits from strong brand recognition in both markets, which typically limits the steepness of any discount, but condition-driven pricing in Japan can still produce gaps worth acting on for buyers comfortable with the import process. The primary risk on this reference is condition variance combined with comp thinness. With only 12 US comps on file, a watch arriving in lower-than-expected condition has limited comparable data to anchor a resale price, and that asymmetry should factor into any purchase decision.
