Its appeal is the contrast between that elaborate dial and a restrained, manually wound dress-watch format; the trade-offs are precious-metal cost, a daily winding ritual, and water resistance described only as “Splash Resistant.”
What makes the SBGW264 distinctive?
Grand Seiko places the SBGW264 in its Elegance Collection and 60th Anniversary limited editions. The company says the green dial pattern evokes white-birch trees near its Shizukuishi studio, and that the dial shimmers green and white as the viewing angle changes. That is Grand Seiko’s design interpretation, rather than an independent performance claim. The official technical description is machine engraving; Time+Tide’s 2021 reviewer described the dial as highly textured and called its pattern guilloche. Grand Seiko’s 2020 announcement explains the design inspiration, while Time+Tide’s review records that reviewer’s impression.

The rose-gold case gives the green dial a warmer frame than a steel watch would. Time+Tide also observed a polished rounded case with a brushed case band. Those are visual impressions, not measured finish specifications. The watch has dual-curved sapphire crystal with anti-reflective coating on the inner surface, a see-through screw case back, and a crocodile-leather strap. Grand Seiko says the back is marked “Limited Edition” and carries a serial number. The official SBGW264 specifications list these construction details.
How does the SBGW264 compare with its sibling?
The directly related alternative is the SBGW263, which Grand Seiko presented alongside it in 2020. The SBGW263 uses platinum and a hand-engraved dial; the SBGW264 uses 18k rose gold and a machine-engraved dial. They share the Shizukuishi-inspired concept, but the dial treatments and case metals distinguish them. Grand Seiko’s announcement identifies the SBGW263 as the 20-piece platinum companion and the SBGW264 as the 120-piece rose-gold edition.

The SBGW263’s smaller edition size does not, by itself, establish a higher resale value. No current secondary-market transaction data is available here for either model.
What are the case dimensions and fit considerations?
The official Australian model page gives the SBGW264 a 39.0 mm case diameter, 44.0 mm lug-to-lug length, and 11.6 mm thickness. The strap is 19 mm wide and made of crocodile leather. These numbers provide a useful starting point, not a fit guarantee: wrist shape and personal preference matter, and the cited sources do not report a fit test.
What movement does it use?
The SBGW264 is powered by Grand Seiko’s hand-wound Calibre 9S64. The movement has 24 jewels, beats at 28,800 vibrations per hour (4 Hz), includes a hacking function, and has an approximately 72-hour power reserve, according to the model specifications and Grand Seiko’s Calibre 9S64 page.
Manual winding makes the watch a deliberate choice for someone who enjoys interacting with a mechanical watch. With an approximately three-day reserve, leaving it unworn for longer than that means it will need winding and resetting before use. The available sources do not document a hands-on winding assessment or an observed power-reserve test.

How should you interpret its accuracy rating?
Grand Seiko lists two different accuracy figures: a mean daily rate of +5 to -3 seconds per day, and normal-usage accuracy of +10 to -1 seconds per day. They are manufacturer specifications, not results from testing an individual SBGW264.
The mean daily rate is measured before the movement is cased, across six positions over 12 days under artificially controlled conditions. The normal-usage figure is a separate manufacturer specification for everyday use. Grand Seiko’s Calibre 9S64 explanation sets out the controlled-test method; neither range guarantees the observed rate of a particular watch.
How much water exposure is it intended for?
Grand Seiko labels the SBGW264 “Splash Resistant.” That wording does not establish suitability for swimming or diving, so treat this as a watch to protect from water exposure rather than one to choose for water activities. The official label appears on the model page.

Grand Seiko’s Australian SBGW264 page currently lists AUD 36,000 and says the watch is available at Grand Seiko boutiques and salons. This is a regional listing, not a confirmed price or inventory statement for other countries. The 5 March 2020 launch announcement also gave an Australian recommended retail price of AUD 36,000 and said the watch would be offered in July 2020; that is launch-era information, separate from the current regional listing. Check the Australian product page for its current listing, and consult a local boutique for availability in your market.

Hodinkee reported a launch-era price of USD 24,000 and July 2020 boutique and salon availability; Time+Tide later reported USD 24,000 / AUD 36,000. These are historical publication figures, not current transaction prices. See Hodinkee’s 5 March 2020 introduction and Time+Tide’s 28 December 2021 review roundup.
For a pre-owned example, check its condition, completeness, provenance, service history, and local asking price with the seller. A 120-piece production run establishes the edition size; it does not establish the condition or value of any individual listing.
Who is the SBGW264 for?
As an editorial judgment, the SBGW264 makes most sense for someone drawn to a richly patterned green dial, a warm precious-metal case, and the involvement of a hand-wound movement. Its dimensions are relatively contained on paper, but individual fit still depends on the wearer. It is a less natural match for someone who wants automatic winding, a watch for swimming, or certainty about local stock and current pricing before contacting a retailer.
