Seiko 5 Sports SRPD91 (SRPD91). Current Prices, JDM Listings, Market Analysis

The Seiko 5 Sports SRPD91 is a JDM-market variant in Seiko's widely followed 5 Sports lineup, a series that consistently draws attention from buyers looking for mechanical watches at accessible price points. The SRPD91 reference sits within a segment where JDM-exclusive colorways and configurations often trade at a discount to their Western-market counterparts, which is exactly why it gets tracked here. Current US market data places the SRPD91 price in the low-to-mid two hundreds, making it a practical target for buyers willing to source from Japan. Market data for this reference is still building, so the figures below should be read with that context in mind.

Current US Market Value

The current US median for the Seiko 5 Sports SRPD91 SRPD91 sits at approximately $220, with the middle 50 percent of transactions falling between $185 and $260. That's a relatively tight spread for a watch at this price tier, though the sample size of five comparable sales is small enough that a single outlier transaction could move those numbers meaningfully. Tonbo rates the comp quality for this reference as limited, denoted by a yellow indicator, which means the pricing picture is directionally useful but not yet statistically deep. Buyers should treat the $220 median as a reasonable anchor while acknowledging that the true market range may be wider than the current data reflects. As more transactions are recorded, confidence in these figures will improve. For now, the data is sufficient for rough valuation but warrants extra diligence before committing to a purchase at the high end of the observed range.

Active JDM Listings

There are no active Japanese marketplace listings for the SRPD91 recorded in the past 14 days. That absence doesn't necessarily indicate low supply over a longer window, but it does mean there is nothing currently surfaced for direct comparison or purchase tracking. When listings for this reference do appear on Japanese platforms, they typically share characteristics common across the 5 Sports JDM segment.

• Listings tend to appear on major Japanese auction and resale platforms, with condition ranging from lightly used to near-new
• Box and papers availability varies and has a measurable effect on final price
• Seller ratings and return policies differ significantly across platforms, affecting effective cost and buyer risk
• Shipping and import fees add to the landed cost and should be factored into any arbitrage calculation
• Inventory can move quickly for sought-after colorways, so alert-based tracking adds real value when supply is thin

Recent Alert History

No strict or opportunity alerts have fired for the Seiko 5 Sports SRPD91 SRPD91 in the past 90 days. This can reflect a few different conditions: a quiet period in Japanese supply, pricing that hasn't broken through the thresholds that define a genuine opportunity, or simply the early stage of data coverage for this reference. It is not a signal that the watch is a poor target, only that no listing has yet met the criteria Tonbo uses to flag actionable pricing. Alert history will build over time as the reference accumulates more coverage.

Japan vs. US Price Gap

The US-Japan price gap for JDM Seiko 5 Sports references is typically driven by the combination of yen-denominated pricing, lower domestic Japanese resale demand for well-produced entry-level mechanicals, and the friction cost that deters casual buyers from sourcing internationally. For a watch trading around $220 in the US, even a modest gap at the source can translate to a meaningful margin once transaction costs are accounted for carefully. The primary risk factor here is comp thinness: with only five recorded US comparables, there is real uncertainty about where a specific example will clear, particularly if condition is anything less than excellent or if the listing lacks original packaging. Buyers should buy SRPD91 Japan listings conservatively until the data set deepens.
