Grand Seiko 62GS 6246-9000 First Automatic Day-Date (6246-9000). Current Prices, JDM Listings, Market Analysis

The Grand Seiko 62GS 6246-9000 First Automatic Day-Date is an early automatic Grand Seiko reference that carries real collector significance as part of the 62GS lineage. It trades quietly in both Japanese secondary markets and among US collectors who track vintage Grand Seiko with any seriousness. The 6246-9000 price in the US sits at an estimated median of $1,700, though the comp base is thin enough that this figure should be treated as directional rather than definitive. We track this reference because JDM supply occasionally surfaces below US replacement cost, and the gap between Japanese asking prices and US resale values can be meaningful when condition aligns.

Current US Market Value

The current US median estimate for the Grand Seiko 62GS 6246-9000 First Automatic Day-Date is $1,700, with the middle 50% of transactions falling between roughly $1,300 and $2,200. That spread is wide, which reflects real condition variance in the vintage market rather than statistical noise alone. The sample size underlying this estimate is three transactions, which is low enough to treat the comp quality rating at face value. Tonbo rates this estimate 🟠 Estimate only, meaning the figures are operator-estimated from available data rather than derived from a deep transaction pool. Anyone using the 6246-9000 price range for a buying or selling decision should weight recent JDM listing activity and any new US comparable sales heavily.

Active JDM Listings

Recent Japanese market activity on the 6246-9000 shows a split between retailer-priced inventory and flea market supply, with one listing standing notably apart from the rest. Most of the current listings cluster in the ¥184,000 to ¥188,000 range across shop platforms, while one flea market listing and one Mercari listing break significantly from that pattern in opposite directions. If you are looking at 6246-9000 for sale in Japan right now, the current landscape looks like this:

• ¥188,001 listed in excellent condition on a Japanese platform (June 3)
• ¥188,000 listed in excellent condition on Yahoo Shop (June 3)
• ¥184,800 listed with unknown condition on Yahoo Shop (June 3)
• ¥94,900 listed on Yahoo Flea with no noticeable scratches or stains noted (June 3)
• ¥349,499 listed on Mercari with unknown condition (May 21)

The ¥94,900 flea market listing is the outlier worth examining. It is priced at roughly half the shop listings, and the seller noted no visible scratches or stains, though condition descriptions on flea platforms require independent verification. The Mercari listing at ¥349,499 sits well above both US median estimates and current shop pricing, which likely reflects either a speculative ask or a particularly well-documented example.

Recent Alert History

No strict buy alerts or opportunity alerts have fired for the Grand Seiko 62GS 6246-9000 First Automatic Day-Date in the past 90 days. This does not mean the model lacks value as a tracking target. With a thin comp base and intermittent JDM supply, alert conditions are harder to confirm with the confidence thresholds Tonbo uses. The flea market listing at ¥94,900 is the kind of data point that, with stronger US comps behind it, could trigger an opportunity signal.

Japan vs. US Price Gap

The buy 6246-9000 Japan opportunity is driven by the same structural factors that apply to most vintage Grand Seiko references. Japanese sellers, particularly on flea and auction platforms, often price against local demand rather than export-adjusted US values, and early automatic Grand Seiko has a stronger collector base in the US and Europe than domestic casual resale pricing tends to reflect. The ¥94,900 flea listing converts to roughly $620 to $650 at current exchange rates, which would represent a meaningful discount to US median if condition holds up on inspection. The primary risk here is twofold. First, the US comp base is thin, so the $1,700 median is not a hard floor. Second, condition variance in vintage automatic Grand Seiko is consequential, and descriptions like "no noticeable scratches or stains" from individual sellers do not substitute for hands-on or detailed photographic assessment.
