Casio G-Shock Metal Bezel 5600 GM-5600 (GM-5600, GM-5600B, GM5600). Current Prices, JDM Listings, Market Analysis
The Casio G-Shock Metal Bezel 5600 GM-5600 sits at an interesting crossroads in the G-Shock lineup, pairing the classic square 5600 case layout with a metal bezel that pushes it slightly upmarket from standard resin models. Tonbo tracks this reference because the JDM sourcing opportunity is real and recurring, with Japan often pricing it below what US buyers pay through domestic channels. At a current US median around $180, the GM-5600 is accessible enough that even modest Japan-to-US arbitrage windows are worth monitoring. Production specifics and movement details for this reference are not confirmed in our dataset, so the focus here stays on what the pricing data actually shows.
Current US Market Value
The current US median price for the Casio G-Shock Metal Bezel 5600 GM-5600 is $180, with the middle 50 percent of transactions falling between $150 and $230. That spread is meaningful for a watch in this price tier, suggesting condition and colorway variation are doing real work on price outcomes. It is worth being upfront about the data quality here. The sample size is just 3 transactions, and the comp source is operator-estimated rather than drawn from a deep pool of verified sales. The comp quality flag is 🟠Estimate only, which means these figures should be treated as a directional reference point rather than a hard market consensus. As more transactions flow through the platform, confidence in this range will improve.
Active JDM Listings
Japan is showing consistent supply of the GM-5600 right now. Four listings appeared on a single day in mid-June, split between Yahoo Flea Market and Komehyo, covering a range of conditions and prices. This kind of supply density is a good sign for buyers looking to source the GM-5600 from Japan. Here is what the recent activity looks like.
- ¥12,400 on Yahoo Flea Market, listed as new condition
- ¥12,000 on Yahoo Flea Market, described as a little damaged or dirty
- ¥11,000 on Yahoo Flea Market, listed with no noticeable scratches or stains
- ¥15,000 on Komehyo, listed with no noticeable scratches or stains
The Komehyo listing commands a premium over the flea market options, which is typical given Komehyo's reputation for grading and authentication. The ¥11,000 Yahoo listing offers the lowest entry point for GM-5600 for sale in Japan, though flea market condition descriptions require independent scrutiny before committing to a purchase.
Recent Alert History
No strict or opportunity alerts have fired for the Casio G-Shock Metal Bezel 5600 GM-5600 in the past 90 days. This does not mean the model lacks value as a tracking target. It reflects a combination of the thin US comp base and the relatively stable Japan pricing shown in current listings. When the data set deepens and a reliable US floor is established, the alert logic has more to work with. You can review how Tonbo's alert tiers are structured at tonbomarket.com/signals.
Japan vs. US Price Gap
At current yen rates, the ¥11,000 to ¥15,000 Japan price range converts to roughly $73 to $100 USD before shipping, proxy fees, and import costs. Even after adding typical landed costs of $30 to $50, the math can work in a buyer's favor against the $150 to $180 lower end of the US range. The GM-5600 price differential exists partly because the model sees strong domestic Japanese supply and does not carry the same export demand as some higher-profile G-Shock references. The primary risk factor here is condition variance on flea market platforms, where descriptions like "a little damaged or dirty" can mean anything. Cross-referencing photos carefully and using a proxy service with photo inspection is the standard mitigation.
