Seiko Prospex 62MAS Modern Reissue (family, all variants) (PROSPEX-62MAS-MODERN-FAMILY). Current Prices, JDM Listings, Market Analysis
The Seiko Prospex 62MAS Modern Reissue family covers Seiko's contemporary returns to the shape and spirit of the original 1965 professional diver, a reference that sits at the foundation of the Prospex line. Tonbo tracks this family as a group because variants share a pricing ecosystem and often appear together in the Japanese secondary market. At a US median of $800, the PROSPEX-62MAS-MODERN-FAMILY price sits in a range where JDM sourcing can produce meaningful savings, particularly on cleaner examples. Comp data here is limited, so every data point carries more weight than it would on a deeper-traded reference.
Current US Market Value
The current US median for the Seiko Prospex 62MAS Modern Reissue (family, all variants) sits at $800, with the interquartile range running from $650 to $1,000. That spread is wider than you would see on a heavily traded model, which reflects the variant diversity within the family as much as it reflects actual price volatility. The comp quality rating is 🟡 Limited comps, meaning the sample size is small and the median should be treated as a directional anchor rather than a precise mark. Anyone pricing a specific PROSPEX-62MAS-MODERN-FAMILY for sale in the US should account for which variant they hold, as dial configuration and case finishing can shift realized prices meaningfully within that $350 spread.
Active JDM Listings
Japan is showing active supply right now, with six listings surfacing in the past 14 days across Yahoo Shop and Yahoo Flea Market. The price range is wide, from around ¥102,500 to ¥390,500, which tells you the market is mixing variants, condition tiers, and possibly deadstock or retailer-priced pieces at the top end. Most of the flea market listings describe condition as clean or close to unused, which is the kind of supply that drives interest when you are looking to buy PROSPEX-62MAS-MODERN-FAMILY Japan.
- ¥390,500 on Yahoo Shop (condition unspecified, likely a retailer or new-old-stock listing)
- ¥235,000 on Yahoo Flea Market, described as showing no noticeable scratches or stains
- ¥170,500 on Yahoo Flea Market, described as close to unused
- ¥146,010 on Yahoo Flea Market, no noticeable scratches or stains
- ¥102,500 on Yahoo Flea Market, no noticeable scratches or stains
The clustering of clean pieces in the ¥102,500 to ¥170,500 range is worth noting. At current exchange rates those figures convert to roughly $680 to $1,130 before fees and shipping, which means the lower end of that JDM supply overlaps with the US p25 price, and the best examples could represent genuine value depending on the specific variant.
Recent Alert History
No strict or opportunity alerts have fired for the PROSPEX-62MAS-MODERN-FAMILY in the past 90 days. That does not mean the model is dormant, it means the recent listing prices have not crossed the thresholds that would trigger a signal worth pushing to subscribers. With limited comps underpinning the model's benchmarks, the alert engine is appropriately conservative.

Japan vs. US Price Gap
The US-Japan price gap on the 62MAS modern family is driven by a combination of collector familiarity and distribution patterns. The 62MAS reissue story resonates strongly with Japanese buyers who have generational context for the original, which keeps domestic supply relatively liquid and domestic pricing competitive. US buyers who source through JDM channels can access that supply at prices that sometimes undercut the US secondary market, particularly on pieces that have never been offered through a US retailer. The primary risk here is condition variance and comp thinness. With a limited sample backing the PROSPEX-62MAS-MODERN-FAMILY price benchmark, a single outlier listing can distort the picture, and verifying a specific variant's fair value before committing requires more due diligence than you would apply to a model with hundreds of tracked sales. Typical JDM sourcing friction, import considerations, and the challenge of authenticating condition from listing photos are all factors to weigh before moving on any piece.
