Every year, collectors speculate on the direction that Grand Seiko is likely to take next. Will it unveil a new movement, bring back a beloved design, or catch everyone off guard with the unexpected? At the Watches and Wonders event in 2026, the Japanese brand did all three. The collection brilliantly combines advanced technology with the craftsmanship and the nature-inspired designs that have made the brand famous.

In many ways, 2026 is the year of Spring Drive. After debuting its revolutionary Ultra Fine Accuracy (U.F.A.) movement last year, Grand Seiko expanded the technology into new collections, including a new diver’s watch. Alongside its latest technical achievements, the brand embraced precious metals with a series of gold and platinum creations. This culminated in a remarkable hand-engraved masterpiece from the Micro Artist Studio. Here’s every watch Grand Seiko unveiled at Watches and Wonders 2026.

The Biggest Grand Seiko Releases at Watches & Wonders 2026

Though Grand Seiko has created many watches for the new collection, the main concept is to design each watch to be worth wearing. From the new Spring Drive technology to dials inspired by nature’s beauty, this year has given us much to consider. So, before we review all the new watches, let us present the ones we liked most.

Ushio’ Diver Spring Drive U.F.A.

Leading Grand Seiko’s Watches and Wonders 2026 lineup is the new Spring Drive U.F.A. Ushio 300 Diver, a pair of professional dive watches featuring the all-new Calibre 9RB1. Building on the success of last year’s Calibre 9RB2, the new movement brings Ultra Fine Accuracy (U.F.A.) to Grand Seiko’s Evolution 9 dive watch collection, delivering an astonishing ±20 seconds per year. That makes the Ushio 300 not only the brand’s most accurate Spring Drive diver to date but also one of the most precise mainspring-powered dive watches ever made.

Named ‘Ushio,’ the Japanese word for ‘tide,’ the two new models were inspired by the waters around the Japanese archipelago. One dial features a deep blue with a subtle gradient that captures sunlight filtering into the ocean depths. The other features a rich green tone inspired by the calmer coastal waters near the shore. Both dials feature an intricate, wave-like pattern that reflects the sea’s constant motion, continuing Grand Seiko’s tradition of translating Japan’s natural landscapes into beautifully textured dial designs.

Housed in a 40.8 mm High-Intensity Titanium case, the Ushio 300 is Grand Seiko’s smallest diver’s watch to date, yet remains every bit a professional tool watch. It offers 300 metres of water resistance, a screw-down crown, a unidirectional ceramic bezel, and a newly developed locking extension clasp with 6 mm of tool-free micro-adjustment, plus an additional 18 mm diving extension for use over a wetsuit. Powered by the Spring Drive Calibre 9RB1, the movement delivers a 72-hour power reserve, 33 jewels, and the signature smooth sweep of the Spring Drive seconds hand. Both models will arrive at Grand Seiko boutiques and selected retailers worldwide in June 2026.

Grand Seiko 'Ice Forest at Dawn' 18CT Gold Spring Drive U.F.A.Ref. SLGB006

‘Ice Forest at Dawn’ 18CT Gold Spring Drive U.F.A.

Its inspiration comes from the frozen forests surrounding Shinshu at daybreak. Grand Seiko has unveiled a more refined interpretation of the Spring Drive U.F.A. in the form of the SLGB006 “Ice Forest at Dawn.” Designed as an elegant dress watch, the boutique-exclusive model is limited to 80 pieces and crafted from 18ct yellow gold. Measuring 37 mm across, it retains the balanced proportions of the Evolution 9 Collection while housing the remarkable Spring Drive Calibre 9RB2, which delivers a 72-hour power reserve and the signature smooth sweep of the Spring Drive seconds hand.

The deep black dial is sprinkled with delicate gold-coloured specks, recreating the rare sun pillar phenomenon that appears when the first rays of sunlight reflect off suspended ice crystals on a winter morning. Paired with a black crocodile leather strap and an 18ct yellow gold folding clasp, this model blends Grand Seiko’s appreciation for Japan’s natural beauty with one of the most accurate mainspring-powered movements ever created, making it an elegant dress watch.

‘Sakura-Wakaba’ 18K Gold Hi-Beat

For collectors who appreciate the warmth of a gold case but prefer the charm of a purely mechanical movement, Grand Seiko introduced the ‘Sakura-Wakaba.’ Housed in a refined 38 mm 18ct yellow gold case, the elegant dress watch is powered by the Hi-Beat Calibre 9S85, operating at 36,000 vibrations per hour (10 beats per second). As one of Grand Seiko’s signature high-beat movements, it delivers the precise performance and smooth operation the brand has become renowned for, while offering a more traditional alternative to the Spring Drive models unveiled this year.

The real highlight, however, is the beautifully textured ‘Sakura-Wakaba’ dial, which takes inspiration from the fleeting moments when Japan’s beloved cherry blossoms begin to give way to newly grown green foliage. As the silvery-green hue of the dial glows in different lighting, it provides an elegantly subtle dial that is unmistakably Grand Seiko. The latest U.F.A. line might well showcase what Grand Seiko can do in terms of technology, but it is worth noting that this is not the only thing the company excels at. Grand Seiko watches are always about capturing the beauty of Japan’s changing seasons and creating truly great watches inspired by them.

‘Iwao Blue’ Manual-Winding Spring Drive 

Grand Seiko also introduced the ‘Iwao Blue,’ a dress watch inspired by the rugged rock formations of the Hotaka Mountains in Japan’s Shinshu region. Its deep blue textured dial reflects the layers and contours of the surrounding landscape, changing character as the light moves across its surface. Compared to some of this year’s bolder releases, the Iwao Blue takes a quieter approach, letting the dial do all the talking.

Powering the watch is the manually wound Spring Drive Calibre 9R31, offering a 72-hour power reserve through its Dual Spring Barrel construction. The movement sits inside a slim 38.5 mm stainless steel case measuring just 10.2 mm thick, making it a natural fit as an everyday watch. Grand Seiko finishes the case with its renowned Zaratsu polishing, a dual-curved sapphire crystal and splash resistance.

Grand Seiko 'Mystic Waterfall' Platinum Spring Drive Ref. SBGZ011

‘Mystic Waterfall’ Platinum Spring Drive

Saving the most extraordinary release for last, Grand Seiko revealed the “Mystic Waterfall” Platinum Spring Drive, a stunning creation made by the famous Micro Artist Studio. Inspired by the flowing waters of Tateshina Waterfall in Shinshu, the watch turns one of Japan’s most beautiful natural sites into wearable art. Every dial is hand-engraved, with many fine lines moving in different directions before converging to show the steady flow of spring water from the earth. This level of skill is achieved by only a few artisans worldwide, making this one of the most impressive luxury watch releases at Watches and Wonders 2026.

The artistry goes beyond the dial. Grand Seiko’s craftsmen have applied the same hand-engraved design across the 40 mm Platinum 950 44GS case, allowing the flowing lines to continue smoothly over the bezel, lugs, and sides. As light moves over the Zaratsu-polished and brushed surfaces, the watch seems to change, creating the look of water flowing over polished stone. The watch comes with two straps you can switch between: a classic black crocodile leather strap and a handmade KYOTO Leather strap with shiny details inspired by the sparkling spray of a waterfall.

Inside the SBGZ011 is the manually wound Spring Drive Calibre 9R02, carefully put together and finished at the Micro Artist Studio. At just 4.0 mm thick, it is Grand Seiko’s thinnest Spring Drive movement and offers an impressive 84-hour power reserve thanks to its Dual Spring Barrel and Torque Return System. Flip the watch over, and you will see beautifully hand-finished parts, an 18k gold “Micro Artist” plaque that can be personalized for the owner, and a barrel engraved with the bellflower, the official symbol of Shiojiri, where the movement is made.

With only 50 pieces available worldwide and sold exclusively at Grand Seiko Boutiques starting in July 2026, the Mystic Waterfall is much more than a luxury wristwatch. Its significance lies in the three elements valued by Grand Seiko: exceptional craftsmanship, technical excellence, and a firm connection to the beauty of Japan’s natural environment. If there was one Grand Seiko that caught our attention this year, it is this one. Mystic Waterfall blends the best of the brand, with remarkable finishing, understated luxury, and outstanding craftsmanship.

What Do We Think About Grand Seiko’s 2026 Releases?

With each release this year, Grand Seiko really mastered the art of watchmaking. Watches and Wonders 2026 presented a lineup that seemed every bit sculpted from Japan’s imposing and breathtaking nature; this seemed to be Grand Seiko’s goal at the event – to showcase the exquisite natural beauty inherent to this remarkable nation through timepieces. If we had to pick favourites, the ‘Mystic Waterfall’ Platinum Spring Drive would be first for its amazing hand-engraved details. The ‘Ice Forest at Dawn’ 18ct Gold Spring Drive U.F.A. is one of the most stylish dress watches Grand Seiko has made in years. Still, it’s hard to choose just one winner, since this is a rare collection where every watch deserves notice. Grand Seiko has carried its strong performance from last year into 2026. If this is where the brand is going, collectors have a lot to look forward to.

TAG Heuer Shoots for the Moon With the Carrera Astronomer Release

  • Each reference features a 39 mm case powered by the dependable Calibre 7 movement with a 50-hour power reserve.
  • The moonphase display shows seven illustrated lunar stages, advancing every night at 1:00 a.m. for a poetic, dynamic visual.
  • Three limited-edition models, each limited to 500 pieces, showcase unique designs featuring steel, modern grey shades, and opulent 18K 5N rose-gold accents.
  • Prices range from USD $4,600 to $7,400, with global availability starting in October 2025 through TAG Heuer boutiques and the official online store.

The race to explore space started when Sputnik 1 broke through Earth’s atmosphere in 1957. That small satellite didn’t just orbit the planet — it sparked a worldwide contest. More unmanned missions followed, including several with animal passengers, and by 1961 the Soviet Union had taken a clear lead when Yuri Gagarin became the first human to travel into outer space.

NASA, still in the early stages of its Mercury program, was struggling to keep up. The agency had achieved only brief suborbital flights with Alan Shepard and Gus Grissom, and genuine orbital travel had yet to be accomplished. Everything changed on February 20, 1962, when John H. Glenn Jr. boarded the Friendship 7 spacecraft. The mission lasted 4 hours, 55 minutes, and 23 seconds as he orbited Earth three times, becoming the first American to do so and marking a turning point in the space race. His mission shaped the decade that followed — and interestingly, he carried a watch that played a small but memorable role in the story.

It took courage, curiosity, and cosmic ambition that TAG Heuer taps into with the Carrera Astronomer. This release honours the era when humanity first looked beyond the horizon and believed we could reach something greater than ourselves.

TAG Heuer’s Space Mission

Before TAG Heuer became synonymous with motorsport timing and modern luxury, the brand quietly earned a place in one of humanity’s greatest achievements. When NASA prepared for its early orbital missions in the 1960s, reliability was more important than branding, and Heuer was among the few manufacturers capable of providing instruments that could withstand extreme conditions. That’s how the company ended up contributing a tool that would soon make history far beyond Earth’s surface.

During John H. Glenn Jr.’s historic 1962 flight, he wore a specially adapted Heuer 2915A stopwatch, making it the first Swiss timepiece to go into space. Originally built for race timing, the 2915A had a long-range 1/5-second measurement system, a seven-jewel movement, and a nickel-chrome case designed for durability. Its dual sub-dial layout allowed Glenn to accurately track minutes, hours, and seconds, operated by simple repeated presses of the crown. While NASA relied on multiple timing systems, Glenn used the Heuer as a backup during critical moments — including launch — where absolute certainty mattered.

The success of the Friendship 7 mission didn’t just change the course of the space race but also reinforced Heuer’s reputation for technical excellence on a global level. Suddenly, the brand was no longer just producing tools for racetracks and laboratories — it had made its mark in orbit. That legacy continues to motivate TAG Heuer’s modern innovations, and with the arrival of the Carrera Astronomer, the brand begins a new chapter in its cosmic voyage, blending heritage with a celestial, design-focused vision for 2025 and beyond.

TAG Heuer Carrera Astronomer

TAG Heuer used Geneva Watch Days 2025 to reveal something truly unexpected with three new references under the Carrera Astronomer name. Instead of revisiting its racing heritage, the brand looked to the moon and drew inspiration from John Glenn’s pioneering mission. The collection combines classic Carrera design with a modern, imaginative take on the moonphase complication, capturing TAG Heuer’s focus on clarity, precision, and innovation.

The watch measures 39mm, creating a balanced profile that feels refined on the wrist, and it is powered by the newly developed Calibre 7 mechanical movement. This calibre drives the Astronomer’s standout feature, which is a moonphase display that breaks from tradition. Instead of a single cutout on the dial, TAG Heuer presents the lunar cycle through a rotating disc that showcases seven illustrations representing each stage of the moon’s 29.5-day cycle.

Positioned at 6 o’clock, the disc advances each night at 1:00 a.m., guided by two slender markers that frame the complication and help track its daily progression. This subtle movement enhances the sense of connection between the wearer and the shifting lunar cycle. Turning the watch over reveals an engraved astronomical observatory surrounded by TAG Heuer’s Victory Wreath, a design choice that honours exploration, achievement, and the cosmic inspiration behind the Astronomer.

The subdued palette with deep grey accents adds atmosphere and movement, with a balanced design framing the lunar disc at 6 o’clock that advances nightly at 1:00 a.m. to show the seven phases of the moon’s 29.5-day cycle. Powered by the new Calibre 7 Movement, it offers modern reliability and poetic storytelling.

TAG Heuer revisited its archives with a modern take on the classic beads-of-rice bracelet from the 1960s, blending vintage charm with contemporary style, fitting the Astronomer’s celestial theme. Rhodium-plated hands with white Super-LumiNova ensure visibility in low light, emphasizing space-inspired design and practicality. The WBX2112.FC6615 is the most understated yet versatile, connecting the Astronomer’s cosmic theme with the familiar Carrera elements.
