Seiko’s Tiny Rectangular Solar Watches Are Now Easier to Buy Outside Japan, but There’s a Price Catch
Seiko’s compact rectangular solar watches are no longer limited to shoppers in Japan, at least not entirely. The four nano・universe Special Edition models, known as the HFJ001P, HFJ002P, HFJ003P, and HFJ004P, can now be ordered internationally through Japanese exporters. For fans of small dress watches, solar-powered movements, and vintage-inspired rectangular cases, that is good news. The less exciting part is the markup.
These Seiko HFJ models were originally positioned as Japan-only releases tied to nano・universe, the Japanese fashion retailer. Seiko lists them as special-edition pieces sold through select physical stores, with no official online sales channel currently shown for overseas customers. That limited availability has made exporters the main route for international buyers who want to add one to their collection.
The watches are appealing because they deliver a very compact, refined look in a case size that is smaller than many well-known rectangular dress watches. Each model measures just 27.4 mm by 18 mm, with a slim 5.9 mm thickness. That makes them especially attractive for anyone looking for a discreet, elegant watch that works well on smaller wrists or with formal outfits.
All four models use Seiko’s solar-powered V115 movement. It is a simple two-hand caliber with an estimated running time of around one year when fully charged. Accuracy is rated at approximately plus or minus 15 seconds per month. The watches also feature Hardlex crystal and basic water resistance suitable for daily use, though they are not designed for swimming or heavy water exposure.
The lineup includes both bracelet and leather strap versions. The HFJ001P comes in a stainless-steel look, while the HFJ002P features a gold-tone finish. The HFJ003P and HFJ004P are fitted with leather straps, giving them a softer and more classic dress-watch feel. Two of the four models therefore lean more jewelry-like, while the leather versions offer a cleaner, traditional style.
In Japan, Seiko’s official pricing starts at 35,200 yen, roughly $220, for the leather models. The stainless-steel HFJ001P is priced at 38,500 yen, or about $241, while the gold-tone HFJ002P costs 41,800 yen, around $262.
International pricing is noticeably higher. One Japanese exporter lists the HFJ001P at 52,900 yen, approximately $331, and the HFJ002P at 57,500 yen, around $360. That works out to a markup of about 37 percent compared with Seiko’s domestic pricing. The leather models are also priced unevenly through export listings, with the black HFJ004P appearing at 48,400 yen, about $303, and the pink-gold HFJ003P at 43,000 yen, around $269, despite both having the same official price in Japan.
Free shipping may apply depending on the seller and order value, but buyers should still factor in local taxes, customs duties, and import fees. For customers in the United States and other regions, these charges may be added during checkout or collected later depending on the platform and shipping method.
The higher price is likely the result of limited distribution rather than upgraded hardware. These remain compact, fashion-focused Seiko solar watches with simple specifications, not luxury mechanical pieces. Still, their charm comes from the combination of Seiko reliability, solar convenience, slim proportions, and a rectangular design that feels both retro and modern.
The collaboration with nano・universe is also not new for Seiko. The two brands have worked together on previous special-edition watches, including older quartz models. This latest HFJ collection continues that relationship with a stronger focus on compact sizing and everyday elegance.
For collectors outside Japan, the question is whether the design is worth paying above retail. If you want one of Seiko’s smallest rectangular solar watches and do not want to wait for a wider release that may never happen, importing is currently the most realistic option. But if price matters most, the premium may be hard to justify.
Even so, the Seiko HFJ001P, HFJ002P, HFJ003P, and HFJ004P stand out in today’s watch market. Small dress watches are becoming popular again, and these models offer a practical solar movement in a genuinely compact case. For fans of minimalist Japanese watch design, this limited nano・universe collection could be one of Seiko’s most interesting small-watch releases of the year.
