All of Grand Seiko’s 2024 Releases

Grand Seiko has a history of tackling the Swiss watch industry head-on. Seiko first showed up at the Neuchatel Observatory chronometer competitions, which had been an annual Swiss-only contest to make the most accurate watch, in 1964. Their watches performed mediocrely. But by 1968, the most accurate mechanical watch at the whole show was a Grand Seiko. So it’s fitting that Grand Seiko is the only Japanese brand at Watches and Wonders Geneva 2024. The Grand Seiko 2024 releases are mostly evolutionary, but a new 38.6mm case size is intriguing, plus they released a new dial texture, and their epic Kodo constant-force tourbillon model comes in a new colorway. Let’s dive in.

Another interesting development is that Grand Seiko has now seemingly positioned its steel and titanium watches into two tiers: typical movement with typical case material (stainless steel or high-intensity titanium), or new-generation movement with advanced alloy (Ever-Brilliant Steel or Bright Hard Titanium). The better tier costs thousands more. You can check our Watches and Wonders 2024 coverage to see releases from more brands. But for now, here’s everything you should know about the Grand Seiko 2024 models.

SBGJ285 Fuji-iro

Grand Seiko marks the second anniversary of its establishment in the Asia Pacific region with the release of the limited-edition SBGJ285, in the familiar and iconic 44GS case. Inspired by the wisteria flower, or Fuji in Japanese, the watch features an intricate light purple dial, known as Fuji-iro.

With a 40mm Ever-Brilliant Steel case, which is more expensive and much harder than stainless steel, the Fuji-iro is powered by the reliable and well-finished Hi-Beat 36000 GMT Calibre 9S86, with a precision of -3 to +5 seconds per day and a GMT function.

SLGA025 Atera Blue

The Grand Seiko SLGA025 “Atera Blue,” part of the Evolution 9 collection, was officially released on September 1, 2024, as a non-limited addition to the brand’s lineup. This model features a High-Intensity Titanium case, a turquoise-emerald textured dial inspired by the waters of Japan’s Atera River, and the advanced 9RA2 Spring Drive movement, offering a five-day power reserve and exceptional accuracy. It is rated to be off by no more than 0.5 seconds per day, instead of the already-impressive 1-second-per-day threshold of a typical Spring Drive.

The new-generation Spring Drive movement and advanced titanium alloy of the case and bracelet (which is more expensive than Seiko’s typical “high-intensity titanium”) push the Atera Blue into five-figure price territory. It’s expensive, but it’s arguably one of the best Grand Seiko dial textures of all.

SLGW004 and SLGW005

SLGW004 and SLGW005 are reinterpretations of the 45GS case with the new-generation manual-winding Hi-Beat Caliber 9SA4. The 9SA4 improves upon its predecessor, the Caliber 9S64, with a higher beat frequency (36,000 vph vs. 28,800 vph), an 80-hour power reserve (up from 72 hours), the cutting-edge Dual Impulse Escapement for greater efficiency, a free-sprung balance with an overcoil hairspring for enhanced stability, and a slimmer profile (4.15mm vs. 4.9mm), while also incorporating a power reserve indicator on the back.

SLGW004 is in 18K gold (limited to 200 pieces), and SLGW005 is in stainless steel (limited to 1,200 pieces)

SBGA507 and SBGA509 Kirazuri

The Grand Seiko SBGA507 and SBGA509 were officially announced on August 1, 2024, and became available shortly thereafter as USA-exclusive limited editions. They both feature beautiful textured “Kirazuri” dials. The 40mm GS case and 9R65 Spring Drive movement will be familiar to Seiko collectors. The $5,600 price point is relatively affordable for a Grand Seiko these days.

SBGD215 Micro Artist Studio Spring Drive

Some say that the finishing of a typical Grand Seiko is on par with an entry-level Patek Philippe, and I would agree. But there’s even a level of Grand Seiko above that: the Masterpiece Collection, which starts at $42,000. Mechanical GS Masterpieces will be made at the prestigious new Atelier Ginza, while ultra-high-end Spring Drive models like the SBGD215, new for 2024, are made at the esteemed Micro Artist Studio in the Japanese Alps.

The SBGD215, like the very similar SBGD213 that came before it, is platinum, coated in diamonds and sapphires, and limited to 8 pieces. Its angular 44.5mm case shape first debuted on the SBGA403 in 2019. Typical Grand Seiko Spring Drives are rated to run at ±1 second per day, but Micro Artist Studio editions bring that down to ±0.5 seconds. Caliber 9R01 also has an eight-day power reserve (instead of the usual three) thanks to three mainspring barrels. Set with 293 gems (148 diamonds and 145 sapphires), ref. SBGD215 will retail for $300,000.

SBGD215 Specs

SBGE307 Spring Drive GMT

There’s also a new Grand Seiko with a Spring Drive movement and that same angular 44.5mm case for those of us who aren’t spending Bentley GT money on a watch. For 2024, we now have the SBGE307, which is a GMT version of the SBGA403. Note that we already had the SBGC253–which is the chronograph and GMT version of the SBGA403. Sometimes I want to rant about Grand Seiko’s product positioning but putting all that aside, this new GMT is a good-looking watch.

Seiko says the dial texture “evokes a lionʼs mane glimmering in the rays of the sun.” I would’ve guessed “steel wool floor buffer pad” but that works too. The 14.9mm case height is a drawback for some people, but the titanium case and bracelet help keep it lightweight. Although Grand Seiko was once viewed as somewhat of a “better value” than Rolex (and largely, they still are) their prices have been increasing in recent years. At $10,700, the Grand Seiko SBGE307 has the exact same 2024 list price as a Rolex Batman GMT.

SBGC275 Spring Drive GMT Chronograph

Grand Seiko historically hasn’t had great success with chronographs. Their first attempt, SBGC001, arrived in 2007 with comically large pushers and it never really got much love from enthusiasts. Perhaps Grand Seiko listened to the complaints, because they seemed to overcorrect that issue with the SBGC249, which has pushers that arguably look too small. But I think the pushers on the new-for-2024 SBGC275 Spring Drive GMT Chronograph are just right.

Well, this SBGC275 is the same thing as 2023’s SBGC253 chronograph, except with a maroon “lion’s mane” dial instead of a silver one. Grand Seiko loves combining GMT’s with chronographs, but maybe if they got rid of the GMT function they could make the case slimmer than 16.8mm. 16.8mm! Oh well. Being limited to 700 pieces, they shouldn’t have too much trouble selling them all, even with a $13,400 list price. The SBGC275 will only be sold at Grand Seiko boutiques.

SLGW003 and SLGW002 Hi-Beat Evolution 9 White Birch

The models I’ve shown you so far are all basically different colorways/configurations of existing models. But for Watches and Wonders 2024, Grand Seiko has also introduced a whole new 38.6mm case size as part of its “Evolution 9” collection. “Low center of gravity” is one of the themes of this collection, and while many Grand Seikos are quite thick, the case height of the new Hi-Beat Evolution 9 White Birch models is just under 10mm.

The White Birch Bark dial texture will look somewhat familiar to Grand Seiko enthusiasts, but it’s actually a bit different than the Birch texture first seen in 2021 on the SLGH005, then the SLGA009. Those original Birch Grand Seikos were 40mm steel watches, and both quite popular. You can think of the new Birch Bark texture on the SLGW002 (rose gold) and SLGW003 (titanium) as a more “close-up” view of a birch tree’s bark.

Also, the 2024 White Birches come on crocodile straps rather than metal bracelets. They feature a new movement, Caliber 9SA4, which is the manual-wind equivalent of the automatic 9SA5 caliber. It’s a slight improvement over GS’s previous manual-wind Hi-Beat movement, 9S64. The 9SA4 provides 80 hours of power reserve (instead of 72) while also managing to be 1.3mm thinner.

Grand Seiko typically uses what they describe as “high-intensity titanium,” but they also released a newer alloy called Brilliant Hard Titanium in 2017. It has only been used on a couple of models since then, and SLGW002 is the latest watch to use this alloy.

Brilliant Hard Titanium is as light as pure titanium but twice as hard as stainless steel and therefore highly resistant to scratches. Its color is brighter than the other forms of titanium used for Grand Seiko and allows the Zaratsu polished surfaces to stand out even more prominently.

Grand Seiko fans have often called for smaller cases–both in terms of diameter and thickness–and that’s exactly what the SLGW003 and SLGW002 deliver. Given the popularity of White Birch dials, I expect these to sell well.

SBGJ277 Snowy Valley Hi-Beat GMT

When describing the SBGJ277, Seiko asks us to “imagine a valley where the highest peaks are capped with snow, even in summer.” You could do that, or you could imagine the SBGJ239 except with a silver textured dial and a bracelet.

The trusty 9S86 movement has been powering SBGJ models (which are all Hi-Beat GMT’s) for over a decade now. It ticks ten times per second, delivering precise timekeeping within the -5 to +3 seconds per day range. Although this watch doesn’t have a new case or movement, it also doesn’t have as high of a price as some of the other Grand Seiko 2024 releases. The SBGJ277 will retail for $6,800.

SLGH021 Genbi Valley Hi-Beat GMT

The SLGH line is Seiko’s three-hand Hi-Beat lineup, and the SLGH013 released in 2022 was the first watch to have a bracelet made of Ever-Brilliant Steel. Most steel Seikos are made out of familiar 316L stainless steel, but Seiko doesn’t call their Ever-Brilliant Steel “stainless” at all. They regard it as a different alloy entirely, noting that it is 1.7 more times more resistant to corrosion than stainless steel, making it “the most corrosion-resistant steel in the world.”

The SLGH021 “Genbi Valley” is the only Grand Seiko 2024 release made from Ever-Brilliant Steel. It’s the same thing as the SLGH013 but with a different textured dial. The dial of the SLGH021 has a “pistachio-flavored snow cone” look to it. It’s a molded texture, not guilloche or laser-etched, but it looks great in pictures. This “Genbi Valley” dial also appeared on SBGH321, SBGW273, SBGW275, and SBGW277.

The price of the newest Genbi Valley has creeped into the five-figure range, but a $10,400 MSRP is forgivable given it has one of the slimmer new-generation movements (9SA5). I won’t repeat too much of Seiko’s flowery language about the “magnificent scenery of the Genbi Valley” that inspired the dial (although I’m sure it’s beautiful), and instead I’ll just mention that all 9SA movements have two mainspring barrels. That’s pretty neat, and it’s how they got the power reserve up to 80 hours.

SLGH021 Genbi Valley Specs

Model	SLGH021
Case Material	Ever-Brilliant Steel
Case Diameter	40mm
Case Thickness	11.7mm

SBGY035 and SBGA499 Hotaka

The Grand Seiko SBGY035 and SBGA499, inspired by the autumnal beauty of the Hotaka mountain range, celebrate the 20th Anniversary of the Spring Drive movement. Both are USA-only limited editions.

The SBGY035 features a minimalist design with a warm auburn red dial and is powered by the manual-winding Caliber 9R31, while the SBGA499 offers a vibrant red sunburst dial with an automatic Caliber 9R65.

The SBGY035 features a more minimalist design with manual winding, while the SBGA499 offers additional functionality with an automatic movement and a date display.

SBGW321 Nishikigoi

The dial of the SBGW321 was apparently inspired by Nishikigoi, or Japanese iridescent carp, swimming in traditional pond gardens. This 2024 Grand Seiko release is exclusive to Europe. It’s a very pleasant dial texture, and the simple time-only display (no date, no power reserve, no GMT hand) really lets it shine. Its modest 36.5mm case, black leather strap, and manual-wind movement make it an extremely “classic”SBGY040  choice.

Here is the specification table for the Grand Seiko SBGW321 Nishikigoi:

Case Material	Stainless Steel
Case Diameter	36.5mm
Case Thickness	11.6mm
Water Resistance	100m
Movement	Caliber 9S64 (Manual-wind)

SBGY040 Chisen Teien

The SBGY040 is another Europe-only Grand Seiko 2024 release, and it has a new Chisen Teien dial texture. According to Grand Seiko, “the deep blue SBGY040 dial is designed to emulate the beautiful moment when ripples on the surface subtly alter the pond’s appearance.”

This solid rose gold beauty retails for over 30,000 euros, and features a manual-wind Spring Drive movement and a relatively slim (10.2mm) case. Only 20 will be made.

SBGW314

In 2020, Grand Seiko released the SBGW259, inspired heavily by the first Grand Seiko model from 1960. It matched the logo style and even the cursive “Diashock 25 Jewels” text of the original. It was a classy three-hand 38mm watch with a titanium case and a rich blue dial. And now Grand Seiko has released a version with a rose gold case: SBGW314. $26,500 is a lot to ask for a Grand Seiko with an aging 9S6 movement, but it’s limited to only 50 pieces.

The Wildest 2024 Grand Seiko Release: SLGT005 Kodo Constant-Force Tourbillon “Daybreak”

Part of the Grand Seiko Masterpiece Collection, the Kodo Constant-Force Tourbillon SLGT005 “Daybreak” features the innovative Caliber 9ST1, a manual-winding movement that integrates a constant-force mechanism and tourbillon on a single axis. This movement made wristwatch history in 2022. This design ensures stable torque and high accuracy, with a power reserve of 72 hours (although for the last 22 hours, there’s too little power for constant-force operation). The entire constant-force carriage acts as a dead-beat seconds indicator.

The SLGT005, which is essentially a lighter colorway of the SLGT003, is housed in a 43.8mm platinum inner case made with a Brilliant Hard Titanium outer case. Its skeletonized dial showcases hand-polished components and blue sapphire jewels, evoking the theme of “Daybreak” through its silver-toned aesthetic. Limited to just 20 pieces worldwide, the SLGT005 comes with a white leather strap treated with traditional Japanese techniques and an additional charcoal grey crocodile strap. Priced at approximately $365,000, Grand Seiko seems to be aiming for Richard Mille territory with this one.

The Last Grand Seiko Release of 2024: Icefall

For their last releases of 2024, Grand Seiko unveiled a new wintery-themed dial texture called “Icefall.” It’s a pleasant light blue color with slightly irregular vertical striations. There are two Icefall models: SBGH347 (37mm) and SBGH349 (40mm). The SBGH347 is made from Ever-Brilliant Steel, which is Grand Seiko’s upscale proprietary steel that they claim is 1.7x harder than stainless steel, although cheaper Grand Seiko models still use regular stainless. Meanwhile, the SBGH349 is made from high-intensity titanium, which is the less expensive of the two Grand Seiko titanium alloys.

Grand Seiko 2024 Releases: In Conclusion

So, all in all, the Grand Seiko 2024 Watches and Wonders offerings didn’t send the world into a tailspin, but it was a decent year. It’s mostly just case/movement/dial rearranging, except for two pretty noteworthy developments: the new Birch Bark dial texture, and the new 38.6mm case size. It will also be interesting to see if Ever-Brilliant Steel and Brilliant Hard Titanium continue to proliferate throughout the Grand Seiko lineup. For now, we already have our eyes on the Grand Seiko 2025 releases.
