Seiko Prospex Turtle Blue SRP773 (SRP773, SRP773K1). Current Prices, JDM Listings, Market Analysis
The Seiko Prospex Turtle Blue SRP773 sits in a well-established corner of the JDM dive watch market, wearing the classic cushion-case silhouette that earned the Turtle nickname decades ago. It trades under reference numbers SRP773 and SRP773K1, with the blue dial variant drawing consistent collector attention from buyers looking for accessible, wearable Seiko dive watches. Tonbo tracks this model because JDM sourcing activity keeps the US-Japan price relationship in motion. At a current US median of $300, it occupies a price tier where arbitrage math can work, but only with accurate landed-cost accounting.
Current US Market Value
The current US median for the Seiko Prospex Turtle Blue SRP773 SRP773 sits at $300, with the middle half of observed transactions falling between $240 and $380. That $140 spread is meaningful at this price level and reflects real condition variance in the secondhand market rather than model instability. One important caveat worth stating plainly: this comp is drawn from a sample size of four transactions and is classified as an operator estimate, flagged with a 🟠quality indicator. That means the figure is directionally useful but should not be treated as a deep-market consensus. Anyone using SRP773 price data to make a sourcing decision should weight it accordingly and watch for additional comp accumulation over time. Tonbo will update the estimate as transaction volume grows.
Active JDM Listings
Japanese market activity for the SRP773 for sale is modest but present. Two listings appeared on June 3rd through Yahoo Shop, pricing the watch in the mid-to-upper ¥60,000 to ¥70,000 range. Neither listing included a disclosed condition grade in the data captured, which is worth flagging before converting any yen figure into a landed-cost estimate.
- Jun 03 listing on Yahoo Shop asking ¥66,660
- Jun 03 listing on Yahoo Shop asking ¥74,900
- Both listings carry unknown condition grades
- No Mercari or other platform listings captured in the past 14 days
- Current JDM supply appears thin, with only two active data points
Recent Alert History
No strict or opportunity alerts have fired for the Seiko Prospex Turtle Blue SRP773 in the past 90 days. This can reflect a few different situations: low JDM listing volume, pricing that hasn't broken below the threshold that would trigger an opportunity signal, or simply a quiet window in what is a lower-volume model. It does not mean the watch lacks value as a tracking target. It means the current market hasn't produced a confirmed signal worth surfacing to subscribers. If you want to be notified the moment conditions change, the alert system at Tonbo Signals is where those notifications originate.
Japan vs. US Price Gap
At ¥66,660 to ¥74,900, the two visible JDM listings translate to roughly $440 to $495 at current exchange rates before shipping, proxy fees, and import costs are applied. Against a US median of $300, those asking prices do not currently support a positive arbitrage case on their own terms. The gap closes or inverts when Japanese sellers price aggressively or when condition grades justify a premium in the US market, which is why active deal tracking matters more than snapshot pricing for this model. The primary risk factor here is comp thinness: with only four US transactions in the dataset and no condition data on the JDM side, a buyer has limited precision when estimating true resale upside. Typical JDM sourcing risks also apply, including condition surprises on arrival and the time cost of the sourcing process.
