Tudor Black Bay GMT S&G Two-Tone M79833 (M79833, 79833). Current Prices, JDM Listings, Market Analysis
The Tudor Black Bay GMT S&G Two-Tone M79833 is one of the more visually distinctive pieces in Tudor's modern lineup, pairing the brand's well-regarded GMT complication with a steel and gold two-tone case treatment that sits in a different register from the all-steel Black Bay GMT variants. It carries enough cross-market appeal to attract both Tudor enthusiasts and buyers looking for a Swiss GMT at a measured price point relative to Rolex alternatives. Tonbo tracks the M79833 because JDM channel pricing on two-tone Tudors can diverge meaningfully from US retail consensus, and the model's condition variance in secondhand markets makes price monitoring useful. At present, the US market positions this reference in the mid-four-figure range, which we unpack below.
Current US Market Value
The current US median price for the Tudor Black Bay GMT S&G Two-Tone M79833 sits at approximately $4,400, with the interquartile range running from $3,800 to $5,000. That $1,200 spread across the middle half of observed sales is relatively wide for a single reference, which reflects both condition differences and the variation you see between box-and-papers examples and stripped pieces. It is important to note that this pricing data carries a 🟡 Limited comps flag, meaning it is derived from a small sample of four transactions. Four data points are enough to establish a reasonable anchor for the M79833 price, but not enough to treat the median as a settled figure. Buyers researching the M79833 price should treat the $4,400 median as directionally useful and watch for more data points to accumulate before drawing firm conclusions about where fair value lands.
Active JDM Listings
There are no active JDM listings for the Tudor Black Bay GMT S&G Two-Tone M79833 recorded in the past 14 days on the Japan market sources Tonbo monitors. This is not unusual for a lower-volume reference. The absence of current listings simply means no M79833 for sale has surfaced in the tracked Japanese market windows recently. When listings do appear, they tend to surface on Japanese auction and marketplace platforms that Tonbo monitors for arbitrage signals.

Recent Alert History
No strict or opportunity alerts have fired for the Tudor Black Bay GMT S&G Two-Tone M79833 in the past 90 days. This means the model has not produced a confirmed JDM pricing signal that cleared Tonbo's thresholds for either a strict deal or a broader opportunity flag during that window. That is worth stating plainly rather than framing it as a negative. Some models go through extended quiet periods in JDM channels before a listing appears at a price worth acting on. The alert history for this reference is simply inactive at present, not negative. Subscribers tracking this model will be notified if that changes.

Japan vs. US Price Gap
Two-tone Tudor models like the M79833 tend to have thinner JDM inventory than their all-steel counterparts, which means the Japan-to-US price gap is harder to characterize with confidence and shifts more on a listing-by-listing basis. When these pieces do appear in Japanese domestic markets, they are frequently priced with the local preference for clean, documented examples factored in, which can compress the arbitrage window relative to what buyers might expect. The most significant risk factor for this specific reference is the combination of thin comparable sales data and condition variance on two-tone cases, where bracelet and bezel wear on gold-accented components affects resale value more sharply than it does on all-steel pieces. Buyers looking to buy M79833 Japan should weight box and papers documentation heavily when evaluating any listing.
