Casio G-Shock Metal Covered GM-110 (GM-110, GM-110B, GM110): Current Prices, JDM Listings, Market Analysis

The Casio G-Shock Metal Covered GM-110 sits at an interesting position in the G-Shock lineup, blending the brand's signature shock-resistant engineering with a metal-covered case construction that pushes it noticeably upmarket from standard resin models. Tonbo tracks the GM-110 because it draws consistent cross-border interest, with buyers in the US regularly looking at Japan as a sourcing channel. The current US median for this model lands at $200, putting it in range for casual collectors and first-time JDM buyers alike. Active Japanese listings confirm that pricing pressure from that market is real and worth watching.

Current US Market Value

The US median price for the Casio G-Shock Metal Covered GM-110 GM-110 currently sits at $200, with the middle 50 percent of transactions falling between $160 and $250. That spread is relatively tight for a watch in this price tier, suggesting reasonably consistent demand without dramatic condition-driven outliers. One important caveat: this estimate is drawn from a sample size of just three data points, and the comp quality is rated 🟠 Estimate only. That means the figures reflect operator estimation rather than a high-confidence dataset built on dozens of verified sales. The GM-110 price picture will sharpen as more transaction data accumulates, but for now, treat the $200 median as a directional anchor rather than a firm market consensus. If you are actively researching GM-110 price trends, checking the Tonbo signals feed will give you the most current read as new comps come in.

Active JDM Listings

The Japanese market is showing live supply right now. Three listings appeared on June 15th across two platforms, and condition across all three skews toward the better end of the spectrum. For anyone looking to buy GM-110 Japan, this is a reasonably active window with asking prices that translate well against the US median once shipping and fees are factored in.

• ¥12,500 on Yahoo Flea Market, June 15 , seller notes no noticeable scratches or stains
• ¥13,500 on Yahoo Flea Market, June 15 , described as close to unused condition
• ¥15,000 on Komehyo, June 15 , also listed as close to unused, sourced through an established Japanese recommerce platform

The Komehyo listing is worth noting specifically. Komehyo operates physical storefronts and applies its own grading standards, which tends to reduce condition ambiguity compared to peer-to-peer flea market listings. The ¥15,000 ask there reflects that modest premium for buyer confidence.

Recent Alert History

No strict or opportunity alerts have fired for the Casio G-Shock Metal Covered GM-110 GM-110 in the past 90 days. That is an honest read of the data, not a gap in coverage. It means recent Japanese asking prices have not dipped far enough below the US median to trigger the threshold-based signals Tonbo uses to flag actionable deals. The current listings are reasonably priced relative to the US market but do not represent the kind of outsized gap that would generate an automated alert. If conditions shift and a meaningful discount appears, the alert logic will catch it. You can review how those thresholds work on the Tonbo deals page.

Japan vs. US Price Gap

At current exchange rates, the three active Japanese listings convert to roughly $80 to $100 USD before factoring in proxy service fees, domestic Japan shipping, and international forwarding costs. All-in landed cost for a GM-110 for sale in Japan typically runs $120 to $150 depending on which proxy or forwarding service you use, which still sits below the US market's $160 to $250 range and creates a realistic arbitrage window. The gap exists partly because G-Shock models move in high volume through Japanese recommerce channels, keeping supply healthy and prices competitive. The main risk factor here is straightforward: thin US comp data means the $200 median could shift meaningfully as more sales are recorded, so buyers relying heavily on that figure for resale math should build in some margin. Condition variance on flea market platforms also warrants close attention to listing photos and seller descriptions before committing.
