Seiko Prospex Mini Turtle PADI (SRPC41/SRPC43) (SRPC41, SRPC41K1, SRPC41J1, SRPC43, SRPC43K1, ミニタートル, Mini Turtle). Current Prices, JDM Listings, Market Analysis
The Seiko Prospex Mini Turtle PADI is a dive-oriented variant in Seiko's Turtle lineup, produced under the SRPC41 and SRPC43 reference families and distributed in both domestic Japanese and international markets. The PADI colorway and branding make it one of the more recognizable sub-variants in the Mini Turtle range, which is why it draws consistent attention from buyers looking for affordable dive watch value. Tonbo tracks this model because its Japan-to-US price gap creates periodic arbitrage windows worth monitoring. Right now the US market is sitting at a median of $400 with verified comps, giving a reasonably clear picture of where deals land and where they don't.
Current US Market Value
The current US median for the Seiko Prospex Mini Turtle PADI SRPC41 price sits at $400, with the interquartile range running from $355 to $449. That spread is tight enough to be useful, meaning buyers and resellers have a reasonably reliable floor and ceiling to work against. The comp pool is based on a sample of 9 recent eBay transactions, which is on the thinner side. With single-digit sample sizes, one outlier transaction can shift the median meaningfully, so treat the $355 to $449 band as directionally correct rather than statistically definitive. Comp quality is rated 🟢 Verified, meaning these are confirmed sold listings rather than asking prices, which is the only number that actually matters for valuation purposes.
Active JDM Listings
The Japanese market is showing a wide spread of asking prices right now, which reflects the mixed-condition landscape you typically find for this model on domestic platforms. The recent two-week window includes both entry-level yahoo_shop stock and higher-priced yahoo_flea listings, with condition ranging from unstated to explicitly new. That kind of spread means sourcing discipline matters more than average here.
- Three separate yahoo_shop listings at ¥11,000 each, all with unknown condition detail
- One yahoo_flea listing at ¥92,700 described as having no noticeable scratches or stains
- One yahoo_flea listing at ¥92,000 listed as new
- One yahoo_flea listing at ¥248,000 listed as new, a significant premium over the other new listing
The ¥11,000 listings stand out immediately. At current exchange rates those would land well below US median even after shipping and import handling, but the absence of condition information on all three is a real flag. The ¥248,000 new listing is almost certainly a collector or set piece given how far it sits above the next-highest new listing, and it has no clear arbitrage case at that price point against US comps.
Recent Alert History
One alert has fired for this model in the past 90 days. On May 27, an opportunity tier signal triggered with a reported landed cost of $431 against a US median of $400, producing a gross margin of negative 8%. That is technically an opportunity tier alert, meaning the system flagged it as potentially interesting relative to historical patterns, but the negative gross margin makes the economics thin at best. No strict tier alerts, which would indicate a cleaner spread, have fired in this window. Buyers watching this model for SRPC41 for sale signals should note that the current alert cadence is low and margins are not wide.
Japan vs. US Price Gap
The PADI colorway carries a branding premium in Western markets, particularly among dive watch enthusiasts, which is the primary driver of the US-Japan price gap on this reference. When Japanese sellers price to local demand rather than export value, the spread can open up, which is what makes the ¥11,000 listings worth investigating for anyone looking to buy SRPC41 Japan stock at a meaningful discount. The main risk here is condition variance combined with thin US comps. Nine transactions is not a deep market, so a watch that comes in below expected condition can stall at resale or require a price cut that erases the margin entirely. Anyone sourcing from listings with no stated condition should budget for that uncertainty before calculating a landed cost.
