Seiko Astron GPS Solar 5X53 Dual-Time Sport Titanium SBXC067 (SBXC067). Current Prices, JDM Listings, Market Analysis
The Seiko Astron GPS Solar 5X53 Dual-Time Sport Titanium SBXC067 is a JDM-market GPS solar watch from Seiko's Astron line, built around the 5X53 movement and positioned as a sport-oriented dual-time reference in a titanium case. It sells domestically in Japan at prices that regularly undercut the US gray market, which is why it shows up on Tonbo's tracking system. At a current US median of $750, the SBXC067 price sits at a level where Japan-sourced examples can land with meaningful margin when condition and timing align. Comp coverage is limited, so every data point here deserves weight.
Current US Market Value
The SBXC067 price in the US currently sits at a median of $750, with the interquartile range running from $600 to $900. That spread is wider than average for a watch at this price point, which reflects both condition variance across listings and the thin comp base. This analysis draws from a sample of five operator-verified transactions, flagged at 🟡 Limited comps quality. That designation matters. A five-transaction sample is enough to orient a buying decision, but not enough to treat the median as a fixed anchor. Anyone tracking the SBXC067 for sale in the US market should treat the $600 to $900 range as the operative window rather than anchoring tightly to the midpoint until more comps accumulate.
Active JDM Listings
Japan is currently showing active supply for the SBXC067. Four listings appeared on May 30 alone, spread across Yahoo Shop and Yahoo Flea Market, with asking prices ranging from ¥75,000 to ¥99,999. Condition descriptions vary noticeably across that range, which is typical for flea market channels where individual sellers grade differently. Here is what the current JDM landscape looks like for this reference.
- ¥75,000 on Yahoo Flea Market, described as no noticeable scratches or stains
- ¥83,000 on Yahoo Flea Market, described as close to unused
- ¥87,780 on Yahoo Shop, condition unspecified
- ¥99,999 on Yahoo Flea Market, described as a little damaged or dirty
The cleanest example at ¥75,000 is the most interesting line here. A watch described as scratch and stain free at the lowest ask is worth scrutinizing closely. The ¥99,999 listing with disclosed damage sits near the top of the range despite the condition flag, which suggests the seller is pricing for the reference rather than the piece. Anyone looking to buy SBXC067 from Japan should weight condition notes carefully given how directly they affect landed resale positioning in the US.
Recent Alert History
Two opportunity-tier alerts have fired for the SBXC067 in the past 90 days, both within the past two days of this writing. The May 29 alert showed a landed cost of $574 against a US median of $750, representing a 23 percent gross margin. The May 28 alert came in at $629 landed against an $800 median at the time, for 21 percent gross margin. Both are opportunity-tier signals, meaning they cleared Tonbo's threshold for actionable Japan-to-US arbitrage. Two alerts in two days points to a window of active supply in Japan, which aligns with the current listing volume visible in the JDM data above.

Japan vs. US Price Gap
The Japan-to-US price gap on the SBXC067 is driven by the standard JDM dynamic. Seiko prices its domestic-market references at levels that do not translate directly into US gray market pricing once demand, scarcity, and the friction of sourcing are factored in. GPS solar technology with dual-time functionality in a titanium case plays well with US buyers who know the Astron line, and that demand supports a premium over what the same watch costs to acquire in Japan after shipping and import fees. The recent landed costs of $574 and $629 against a $750 US median show the gap is real and currently accessible.
The main risk here is comp thinness. With only five verified US transactions on record, a single outlier in either direction moves the median more than it would in a deeper dataset. Condition variance in the JDM listings adds a second layer of uncertainty. The ¥99,999 listing flagged as damaged is a useful reminder that not every SBXC067 for sale in Japan will land at a condition grade that supports the US median price. Sourcing discipline on condition is the primary lever a buyer controls. You can browse current deals tracked across JDM references at tonbomarket.com/deals.
