Grand Seiko


The precision craftsmanship and materials required to created a Japanese Katana sword inspires three new U.S.-exclusive Grand Seiko watches.

Grand Seiko SBGA489 and SBGA491.

The debut trio offers a choice of stunning deep red, green or black dials, each framed in a 40mm diameter by 12.5mm stainless steel case. Each features a stainless steel bracelet with a three-fold clasp, a dual-curve sapphire crystal and a clear sapphire case back exposing the superb Spring Drive Automatic Caliber 9R65 (see specifications below).

The new Grand Seiko SBGA493 is a limited edition of 500 pieces.

Grand Seiko explains that the high-carbon steel known as kawagane used for the outer sharp edge of katana sword inspired the black dial of SBGA489 debut model. Similarly, dial artists echoed the strong inner core of the blade (the shingane) when creating the dark green dial of SBGA491.

For the limited-edition model SBGA493 with the striking red patterned dial Grand Seiko specifically references “the determination and fiery spirit needed to craft the blade.

The deep red color with yellow gold-tone accents is influenced by the heated blade during the forging process. The pattern emulates the radiating sparks created when the hammer strikes the blade.”

Grand Seiko is issuing the red-dialed edition (SBGA493) as a limited edition of 500 pieces available in September, each priced at $6,000. The black-dial model (SBGA489) and the green-dial model (SBGA491) are priced at $5,600, and both are available now.

A year after Grand Seiko introduced complicated and sporty models to its  Evolution 9 Collection, the watchmaker adds its first automatic chronograph to the collection.

The new Grand Seiko Tentagraph.

The new model, the Tentagraph, features Grand Seiko’s high-beat (36,000 mph) movement, Caliber 9SA5, which is enriched with two barrels and an ultra-efficient Dual Impulse Escapement. The existing GMT chronograph within Evolution 9 is powered with Grand Seiko’s Spring Drive technology (Caliber 9R96). 

With these technical enhancements, Grand Seiko says the Tentagraph will retain its power reserve in chronograph operating mode for seventy-two hours, which the watchmaker call the “longest power reserve in the industry today.”

Grand Seiko tests its Tentagraph movement for twenty days with a strict precision goal of +5 to -3 seconds per day.

The new 43.2mm by 15.3mm titanium-cased watch retains the eye-catching Evolution 9 textured dial finish, here colored blue. The dial’s large indexes and recessed sub-dials deliver a quick read for the wearer.

Grand Seiko also gently curves the chronograph seconds downward so that the tip of the hand is as close as possible to the dial’s markers, again enhancing legibility.

The chronograph features a running seconds sub-dial at the three o’clock position, a 30-minute chronograph counter at nine, and a 12-hour chronograph counter at six o’clock.

Grand Seiko’s own proprietary Dual Impulse Escapement efficiently transfers energy to the free-sprung balance wheel indirectly through the pallet fork and also directly from the escape wheel, enhancing the movement’s efficiency.

In addition, Grand Seiko builds a vertical clutch and a column wheel into the movement, both of which enhance accuracy and chronograph control.

On the dial Grand Seiko places its signature Mt. Iwate pattern, named for the nearby mountain visible through the windows of the Grand Seiko Studio Shizukuishi.

The Tentagraph’s bezel is made of ceramic.

The Grand Seiko will make the Tentagraph available at the Grand Seiko Boutiques and select retail partners starting in June. Price: $13,700.

New Masterpiece

At Watches and Wonders 2023 Grand Seiko also debuted a hand-engraved, manual-wind platinum model in its Grand Seiko Masterpiece Collection.

Its dial consists of the now familiar Shinshu white birch pattern, though here Grand Seiko artisans have added a slightly different tone and a more metallic texture.

Inside Grand Seiko fits its Spring Drive Caliber 9R02 (first seen in 2019). The caliber’s superb eighty-four hour power reserve is the result of a dual spring barrel in which both mainsprings are set in parallel within the single barrel. 

Grand Seiko has set an 18-karat gold plaque on the 38.5mm watch’s lower bridge engraved with the words “Micro Artist.” However, the owner can instead customize it. Price: $79,000 (limited edition of fifty).

Finally, Grand Seiko introduces a Spring Drive jewelry watch inspired by the Brand’s emblematic white lion. The watch’s case and dial gleam with 5.62 carats of diamonds and 1.25 carats of blue sapphires, all set by hand.

The sapphire crystal case back reveals a beautifully finished Caliber 9R01 movement’s one-piece bridge, designed in the image of Mt. Fuji. Price: $260,000. 

Grand Seiko debuts Spring Drive SLGA021, a new model in its fairly new (2020) nature-inspired Evolution 9 collection. 

The 40mm steel watch features a blue dial created to echo the ‘gently lapping waters’ of Lake Suwa near the Shinshu Watch Studio, where the watchmaker builds Spring Drive watches.

Not only does the dial appear to mimic waves, its color changes depending on the angle and amount of nearby lights, also echoing the experience of gazing into a lake.

As on its Evolution 9 brethren, the dial here is eminently readable. Grand Seiko cuts the hour hand at the tip and extends the minute hand right to the minute track so that the hands are more clearly differentiated than is typical on many other watches. For the same reason, Grand Seiko makes the 12 o’clock index especially wide for instant identification regardless on viewing angle.

Grand Seiko fits the watch with its excellent Caliber 9RA2 Spring Drive movement, which boasts a long power reserve of five days, or about 120 hours.

All Caliber 9RA2 Spring Drive movements are protected from magnetic fields up to an enhanced 4,800 A/m.

Price: $9,100.

Grand Seiko will be donating proceeds from the Phillips New York Watch Auction: SEVEN on December 10-11 to two charities.

Grand Seiko’s Kodo Constant-Force Tourbillon, unique edition (Ref. SLGT001).

The profit from the sale of select modern Grand Seiko timepieces during the auction will be donated to the Fairchild Tropical Botanical Garden in Miami, Florida. Its commitment to the environment perfectly aligns with the brands Nature of Time” philosophy and recognizes the importance of the natural world as a source of inspiration and creativity, according to Grand Seiko.

Funds raised from the auction of special piece-unique Grand Seiko Kodo Constant-force Tourbillon (Ref. SLGT001) will be donated to the Childrens Heart Foundation, a leading organization dedicated to funding congenital heart defect research. 

Unique piece

The Grand Seiko Kodo up for auction is unique in several ways when compared to the global model, reference SLGT003, which is limited to twenty pieces.

First, the multi-component case structure is made entirely of Grand Seiko’s proprietary alloy, Brilliant Hard Titanium. In addition, Grand Seiko colors the bridges, mainplate, and many of the components of the movement in a plated silver color. Finally, on this unique piece Grand Seiko has hand-tempered the screws blue instead of mirror polishing them, as they are on reference SLGT003.

The top bidder will also receive a trip to Japan to meet its creators, the Grand Seiko team, and a visit to Grand Seiko Studio Shizukuishi in the Iwate prefecture.

The Kodo Constant-Force Tourbillon, introduced earlier this year, is Grand Seiko’s first mechanical complication watch. It features an unusual movement that delivers high accuracy by combining a tourbillon and a constant-force mechanism as one unit on a single axis for the very first time in horological history. The watch is named Kodo, the Japanese word for heartbeat. 

Grand Seiko adds two new GMT models to its Sport Collection, and both are powered by the hyper-precise Grand Seiko quartz Caliber 9F86.

The duo, Grand Seiko models SBGN027 and SBGN029,  both feature a design built with a 39mm steel case, slightly smaller than most models in the collection.

New Grand Seiko model SBGN027, one of two new GMT watches in the Sport Collection.

One model, SBGN029, features a blue sunray dial with red accents—-most notably a red GMT hand to indicate a second time zone. The other debut, SBGN027, features a black sunray dial with monochromatic highlights.

Using the clearly differentiated GMT hand, the wearer of either model can quickly note the second time of choice using the 24-hour dial ring, which is divided into two 12-hour sections for AM and PM.

Both watches offer hands and dial indexes with generous Lumibrite coating for superior visibility in darker conditions. In addition, each watch is rated to 100 meters of water resistance and features a screw-down crown and a dual-curve sapphire crystal.

Grand Seiko supplies both models with its well-known three-row steel bracelet with high-end Zaratsu-polished surfaces .

Grand Seiko collectors are familiar with Caliber 9F series, which the watchmaker created as the “ultimate quartz watch.” This Caliber 9F86 provides extremely high accuracy, with a rating of +/-10 seconds a year. And critically for a travel watch, the movement allows the wearer to adjust the hour hand without interrupting the timekeeping.

Price: $3,300 (available in September).
