Citizen Attesa GPS Satellite Radio CC4050-18L (CC4050-18L, CC4050). Current Prices, JDM Listings, Market Analysis
The Citizen Attesa GPS Satellite Radio CC4050-18L sits at the upper end of Citizen's Attesa lineup, combining GPS satellite timekeeping with radio-controlled synchronization in a watch built primarily for the Japanese domestic market. Because it rarely surfaces through official retail channels in the US, the CC4050-18L price is shaped almost entirely by secondary market supply from Japan. Tonbo tracks this model because the US-Japan price gap has shown consistent arbitrage windows for buyers who can move quickly on well-priced JDM inventory. The current US median sits at $900, with a spread from $780 to $1,000 at the interquartile range.
Current US Market Value
Based on operator-verified comparables, the Citizen Attesa GPS Satellite Radio CC4050-18L CC4050-18L carries a current US median of $900. The 25th-to-75th percentile range runs from $780 to $1,000, which suggests relatively tight pricing on clean examples but room for variance on pieces with condition issues or incomplete packaging. It is worth noting that the comp pool here is limited. Tonbo rates this model at 🟡 Limited comps, meaning the median reflects genuine transactions but fewer than we would want for high-confidence pricing. Treat the $900 figure as a directional benchmark, not a guarantee, and weight condition heavily when assessing any specific piece.
Active JDM Listings
Japan-side supply for the CC4050 is active right now. As of late May, multiple listings appeared on the same day across Mercari Japan and a Japanese auction platform, covering a wide price range that signals real variation in seller expectations and likely in condition as well. Anyone looking to buy CC4050-18L Japan should note that the spread from roughly ¥99,000 to ¥220,000 is unusually wide, which means due diligence on each listing matters more than usual.
- ¥98,780 listed on a Japanese auction platform
- ¥112,000 listed on Mercari Japan
- ¥138,000 listed on Mercari Japan
- ¥168,000 listed on Mercari Japan
- ¥220,000 listed on a Japanese auction platform
All listings above were observed on May 30. Condition details were not confirmed at the time of data capture, which is consistent with how JDM listings often appear without thorough disclosure.
Recent Alert History
The CC4050-18L has generated meaningful alert activity over the past 90 days, with four signals fired between May 25 and May 28. Two of those were strict-tier alerts, the higher-confidence tier that Tonbo issues when landed cost, expected fees, and US comps align cleanly. One strict-tier alert landed at $690 against a US median of $1,140 at the time of the alert, representing a 39% gross margin. A second strict-tier alert landed at $964 against the same $1,140 median, showing a tighter but still positive 15% gross margin. One opportunity-tier alert landed at $736 against the $1,140 median for a 35% gross margin. The fourth was a strict-tier alert at $1,042 with a 9% gross margin, which sits at the lower edge of actionable range. The presence of alerts at multiple price points in a short window suggests that Japan-side supply is moving and that pricing is not yet stabilized.

Japan vs. US Price Gap
The CC4050-18L for sale in Japan trades at prices that reflect local supply abundance and lower domestic resale demand for a watch that was never marketed in the US. American buyers who understand the model can acquire examples at landed costs that sit materially below what the US secondary market will bear, particularly on lower-priced Japanese listings where the seller is clearing inventory rather than optimizing for value. Shipping, import duties, and any intermediary fees typically add $100 to $200 to a landed cost calculation, which is already reflected in the alert data above.
The main risk on this model is comp thinness on the US side. With limited verified sales, any single transaction can move the apparent median, and a watch that takes longer than expected to sell will carry holding cost against a benchmark that may not hold. Condition variance on JDM listings without photos or grading adds a second layer of uncertainty, particularly at the lower end of the Japan price range.
