Grand Seiko 62GS 6246-9001 First Automatic Day-Date (6246-9001): Current Prices, JDM Listings, Market Analysis

The Grand Seiko 62GS 6246-9001 First Automatic Day-Date is a vintage Grand Seiko reference that represents the brand's early push into automatic movements with a day-date complication, a meaningful milestone in the 62GS lineage. It surfaces regularly enough in the Japanese secondary market to be worth tracking, and its price gap between Japan and the US creates occasional buying opportunities for collectors willing to navigate JDM sourcing. The current US median sits at $1,500, with active Japanese listings clustering well above and below that figure depending on condition. Tonbo tracks the 6246-9001 price across both markets to give buyers a cleaner read on where value actually sits.

Current US Market Value

The US median for the Grand Seiko 62GS 6246-9001 First Automatic Day-Date is currently $1,500, with the interquartile range running from $1,100 to $2,000. That $900 spread is wide for a single reference, which reflects genuine condition variance across the sample rather than price ambiguity. It is worth being direct about the data quality here: this analysis is built on six comparable sales, which earns a 🟡 Limited comps rating. The median is a reasonable directional anchor, but buyers should treat the full $1,100 to $2,000 range as live territory rather than treating $1,500 as a firm price. As more sales accumulate, the picture will sharpen. For a real-time view of where deals are clearing, check the Tonbo deals tracker.

Active JDM Listings

Japanese marketplace activity for the 6246-9001 as of early June shows a clear split between good-condition examples priced in the ¥250,000 to ¥270,000 range and damaged or lower-grade pieces priced significantly lower. That spread is important context for anyone looking to buy 6246-9001 from Japan, since the condition tier is doing a lot of the pricing work here. A damaged piece at ¥107,500 and a good piece at ¥270,000 are not competing with each other in any practical sense.

• ¥260,000 on Yahoo Shop, condition rated good
• ¥270,000 on Yahoo Shop, condition rated good
• ¥147,510 on Yahoo Shop, condition rated good
• ¥130,000 on Yahoo Shop, condition rated damaged
• ¥107,500 on Yahoo Shop, condition rated damaged

The good-condition cluster at ¥147,510 to ¥270,000 translates to roughly $970 to $1,780 at current exchange rates, which puts some of those listings inside or near the US interquartile range before shipping and import costs are factored in. The lower end of that cluster is where the 6246-9001 for sale interest tends to concentrate for arbitrage-minded buyers.

Recent Alert History

No strict buy alerts or opportunity-tier signals have fired for the Grand Seiko 62GS 6246-9001 First Automatic Day-Date in the past 90 days. That does not mean the model is uninteresting, but it does mean that no listings have cleared the thresholds Tonbo uses to flag genuine outliers. With a thin comp base and active listings spanning a wide price range, the model is in a monitoring phase rather than an active alert phase. Subscribers watching this reference through Tonbo Signals will be notified when a listing crosses the relevant thresholds.

Japan vs. US Price Gap

The US-Japan price gap for this reference is driven primarily by discovery friction. The 62GS automatic day-date variants are not as heavily covered in English-language watch media as some other Grand Seiko references, which keeps US buyer awareness lower and allows Japanese listings to sit at prices that would move faster in a more visible market. The good-condition listings at ¥147,510 in particular sit close enough to the US low end that, after realistic sourcing costs, the margin is thin but present.

The main risk here is not the arbitrage math but the condition variance. Damaged examples at ¥107,500 and ¥130,000 are priced attractively on paper, but restoration costs on vintage Grand Seiko cases and dials can eliminate any spread quickly. The limited comp sample also means that one outlier sale can move the US median materially, so buyers should anchor to the full price range rather than the median alone when evaluating a specific piece. Typical JDM sourcing risks around authentication, shipping, and import duties apply as they do across all Japanese market purchases.
