Seiko Presage Sharp Edged GMT Green (Suzu Iro) SPB221J1 (SPB221J1, SPB221). Current Prices, JDM Listings, Market Analysis
The Seiko Presage Sharp Edged GMT Green (Suzu Iro) SPB221J1 is a Japan domestic market release from Seiko's Presage Sharp Edged series, notable for its Suzu Iro dial , a muted, traditional Japanese green that reads differently across lighting conditions than most production dial greens. It carries the GMT complication and sits at a mid-tier price point within the Presage lineup, making it a model that attracts both collectors focused on JDM exclusivity and buyers looking for a wearable GMT at a reasonable cost of entry. Tonbo tracks it because JDM-only references like the SPB221J1 can surface at meaningful discounts through Japanese secondary channels that US-based buyers rarely monitor consistently. At current observed pricing, the SPB221J1 price sits just above $1,100 in the US market.
Current US Market Value
The current US median for the Seiko Presage Sharp Edged GMT Green (Suzu Iro) SPB221J1 SPB221J1 is $1,140, based on verified eBay transaction data. It is worth being direct about the sample context here. This figure is drawn from a single verified sale, which means the median, the 25th percentile, and the 75th percentile all converge at $1,139. That tight range is a product of thin comp volume, not unusual price stability. The comp quality rating is 🟢 Verified comps, meaning the underlying transaction was confirmed as a legitimate sale rather than an unsold listing or an inflated ask. Treat the $1,140 figure as a reasonable anchor for SPB221J1 price research, but apply wider uncertainty bands than you would for a model with dozens of recent sales. As more transactions are recorded, this figure will sharpen.
Active JDM Listings
There are no active Japanese market listings for the SPB221J1 recorded within the past 14 days. This is not necessarily a negative signal for buyers , it can reflect natural inventory rhythm in the Japanese secondary market, where stock for a specific JDM reference like this one moves in bursts rather than continuously. Gaps between visible listings are common for lower-volume Presage references. When supply does reappear, it tends to show up across the major Japanese resale platforms. Key things to watch for when listings do surface for buy SPB221J1 Japan searches:
- Condition grading from the Japanese seller, particularly around dial surface and crown area wear
- Whether box and papers are included, which materially affects the landed value relative to US comps
- Platform-specific buyer protections, which vary across Japanese auction and fixed-price channels
- Shipping and import cost estimates, which affect the real arbitrage margin versus the $1,140 US anchor
- Seller rating history, especially for overseas transaction experience
Recent Alert History
No strict or opportunity alerts have fired for the SPB221J1 in the past 90 days. This reflects the low listing velocity noted above rather than a model being consistently overpriced. When there are no Japanese listings entering the tracked channels, there are no triggers to evaluate against the alert thresholds. It does not mean the watch is unavailable at good prices , it means the window for a data-backed signal has not opened recently. Buyers with active interest in this reference should set up monitoring now so they are positioned when supply returns, rather than reacting after listings have already moved.

Japan vs. US Price Gap
The SPB221J1 is a Japan domestic market reference, which means retail access in the US is structurally limited. That distribution gap is what creates the potential for a price differential between Japanese secondary market prices and the US resale level observed around $1,140. Buyers who can navigate JDM sourcing competently , handling proxy purchasing, shipping logistics, and import duties , can sometimes land this watch below the US market rate, though that margin is not guaranteed and fluctuates with yen exchange rates. The primary risk factor here is comp thinness. With only one verified US sale on record, there is limited confidence in where the true market would clear if multiple units were offered simultaneously. Condition variance on the Japanese side adds a second layer of uncertainty, since dial color accuracy and surface condition on a watch with a distinctive Suzu Iro green can significantly affect desirability to US buyers.
