Grand Seiko Spring Drive 8-Day Jewelry Watch, Reference SBGD213

The lion symbol has been closely associated with the Japanese’s premium watch label since its launch. Introduced in 1960, the first Grand Seiko watch came with a gold medallion depicting a lion graced the case back.

In 2022, Grand Seiko introduced a Spring Drive jewelry watch (SBGD209) inspired by the white lion. Now the brand is offering a novelty Spring Drive model that reflects the strength and power of this majestic creature.

Grand Seiko Spring Drive Jewelry Watch, Reference SBGD213

A new addition to the Masterpiece collection, Grand Seiko SBGD213 comes with a 44.5mm diameter case in platinum. Adorned with sparkling diamonds, the case has strong and angular lugs denoting the power of the lion. The upper surfaces of the case feature 112 diamonds and 60 baguette-cut diamonds adorn the bezel. A single brilliant-cut blue sapphire is set into the crown.

The mother of pearl dial has a distinct blue shade, representing Grand Seiko’s signature color. Surrounding this dial, the tapered blue sapphires and baguette diamonds serve as hour and minute markers.

Forty-eight additional diamonds and 12 blue sapphires are individually set around the markers, enhancing the depth and beauty of the dial. The grey colored seconds hand matches the overall tone.

Finished with a special Zaratsu polishing technique specially developed for Platinum 950, the case spotlights a distortion-free mirror finish. This new model comes with a black alligator leather strap.

Grand Seiko Spring Drive Caliber 9R01

The Grand Seiko SBGD213 watch houses the Caliber 9R01, a manual-winding Spring Drive movement. It is accurate to ±10 seconds per month and offers a power reserve of eight days, thanks to its three barrels arranged in sequence. The sapphire crystal case back reveals the exquisite finishing of the movement’s one-piece bridge, designed in the image of Mt. Fuji.

Grand Seiko Spring Drive Platinum “White Birch” Reference SBGZ009

Grand Seiko presents a new manual-winding Spring Drive watch with a fully engraved platinum case and a beautiful white birch dial. Limited to 50 pieces, this new timepiece (reference SBGZ009) from the Grand Seiko masterpiece collection is a bona fide product from the Micro Artist Studio.

Grand Seiko Reference SBGZ009 Spring Drive Platinum White Birch

Based in Shiojiri in the Shinshu region of Japan, the Micro Artist Studio makes exclusive Spring Drive watches for Grand Seiko. The highly skilled craftsmen and women of this luxury watch atelier handcraft timepieces embodying the beauty of the local surroundings and seasons.

Grand Seiko SBGZ009 is the latest product from this prestigious high horology workshop. It boasts a stunning dial with textures inspired by the expansive forest of white birch trees found at the foot of the North Yatsugatake Mountains in the eastern part of Shinshu.

Grand Seiko Spring Drive Platinum “White Birch” Reference SBGZ009

The silver color dial with its texture evokes white birch forest as it appears during the height of winter, covered by freshly fallen snow.

Made of 14k white gold, the hour and minute hands, as well as each of the hand-applied diamond-cut markers boast a sharp and gleaming finish. The minute track, the lettering and the mark at six o’clock are all carved into the dial. The tempered seconds hand has a harmonious grey dial.

The star mark at six o’clock denotes solid gold hour markers, a Grand Seiko tradition since the 1960s. The minute and seconds hands are shaped by hand to curve gently towards the minute track, ensuring high legibility.

Engraved Platinum Case

The 38.5mm diameter case in Platinum 950 perfectly harmonizes with the much admired Shinshu white birch pattern dial. Fully engraved, it spotlights a distortion-free mirror surface achieved through the Zaratsu polishing technique.

Engraved Platinum Case

The long individual grooves of the case are painstakingly hand-engraved by the skilled engravers of the Shinshu Watch Studio, which is in the same facility as the Micro Artist Studio. Each groove brings to life the array of white birch trees in a pattern that seamlessly echoes a similar pattern found on the dial.

Grand Seiko Spring Drive Caliber 9R02

The Grand Seiko SBGZ009 White Birch watch houses the manual winding Spring Drive Caliber 9R02. Introduced in 2019, this movement comes with Dual Spring Barrel and Torque Return System. It also offers an outstanding 84-hour power reserve.

Spring Drive Caliber 9R02

Visible through the sapphire crystal case-back, Caliber 9R02 demonstrates the exquisite craftsmanship that is the hallmark of the Micro Artist Studio.

Its barrel has a decoration echoing the bellflower, the symbol of Shiojiri. The two hand-finished bridges with high-polished edges contrast the fine hairline finishing of their other visible surfaces. An 18k gold plaque set on the lower bridge is engraved with the words “Micro Artist,” but if the owner wishes, this plaque can be customized.

Grand Seiko Reference SBGZ009 Spring Drive Platinum White Birch

Grand Seiko SBGZ009 is only the third fully engraved masterpiece powered by a manual-winding Spring Drive movement. It will be available as a limited edition of 50 pieces at the Grand Seiko Boutiques in June 2023.

Grand Seiko Tentagraph Reference SLGC001

Grand Seiko presents Tentagraph (reference SLGC001), the first mechanical chronograph from the Japanese premium watch brand. This timepiece houses the high-beat Caliber 9SC5 with three days of power reserve. This new model from the Evolution 9 collection has a gentle blue color dial with a beautiful texture inspired by the Mt. Iwate.

Grand Seiko Tentagraph Reference SLGC001

In 2022, Grand Seiko introduced its first mechanical complication and a series of Spring Drive sports watches from the Evolution 9 Collection. The brand is now expanding the GS Evolution 9 series with its first mechanical chronograph, the Tentagraph. Its calibre is based on the revolutionary high-beat Caliber 9SA5.

Grand Seiko Tentagraph Caliber 9SC5

Like Caliber 9SA5, the new Tentagraph Caliber 9SC5 beats ten times per second, ensuring high accuracy when measuring elapsed time as well as the time of day. And, thanks to its energy-efficient escapement and two barrels, the watch runs for three days even when the chronograph is in operation.

Caliber 9SC5 Automatic

Visible through the exhibition case back, the Grand Seiko Caliber 9SC5 movement features the revolutionary Dual Impulse Escapement. This component efficiently transfers energy to the free-sprung balance wheel indirectly through the pallet fork and also directly from the escape wheel.

The brand uses MEMS technology to manufacture extremely precise, lightweight, and highly durable escapement parts. It endows the escapement with increased energy efficiency to achieve a long power reserve.

Grand Seiko Tentagraph Reference SLGC001

This modern chronograph movement with a vertical clutch and a column wheel offers high accuracy and operability.

Grand Seiko Tentagraph SLGC001

A genuine mechanical sports chronograph, the Grand Seiko Tentagraph SLGC001 comes with high-intensity titanium case and titanium. Measuring 43.2mm in diameter, the case with a curved profile features wide lugs for accommodating a 23mm bracelet. It also fuses the Zaratsu polished, distortion-free mirror finished surfaces with delicate hairline finished ones.

It also hosts two convex pushers (at 2H and 4H) for operating chronograph function. The ceramic bezel protects the watch from scratches and enhances durability.

The GS SLGC001 has a Mt. Iwate pattern dial with prominent indexes and recessed sub-dials, adding substantial depth and legibility to the design. First introduced in 2006, this distinctive dial pattern evokes the ridged contours of the nearby mountain visible through the windows of the Grand Seiko Studio Shizukuishi.

The bold hands and large grooved indexes with Lumibrite further enhance night time legibility. The dial hosts a running seconds sub-dial at 3H, a 30-minute chronograph counter at 9H, and a 12-hour chronograph counter at 6H.

The chronograph seconds hand is gently curved down towards the dial so that the tip of the hand is as close as possible to the dial’s markers and extends to the markings at the very edge of the dial. The minute hand is also gently curved to ensure the legibility.

Grand Seiko Tentagraph Reference SLGC001

The Tentagraph will be available at the Grand Seiko Boutiques and select retail partners starting in June 2023.

Grand Seiko Spring Drive Chronograph GMT Ref. SBGC253

In 2019, Grand Seiko introduced a new sports watch design inspired by the iconic Grand Seiko lion symbol. Now the brand presents a new Spring Drive Chronograph GMT watch with the same powerful design. This latest reference belongs to the Grand Seiko Sport Collection.

The lion symbol reflected the aim of the original Grand Seiko team to create the very best timepiece of which they were capable in terms of accuracy, durability and beauty.

Grand Seiko Spring Drive Chronograph GMT Ref. SBGC253

The lion makes its presence felt on the new Grand Seiko Spring Drive watch in several ways. The strong and angular case has claw-like, hairline-finished lugs that stand out from the Zaratsu-polished elements.

GS Spring Drive Chronograph GMT Lion’s Mane Dial Version

The Grand Seiko Spring Drive Chronograph GMT (reference SBGC253) boasts an ivory-white textured pattern dial inspired by “lion’s mane”. The dark red accents on the dial allow the wearer to read the time at a glance. The hour and minute hands are designed for heightened legibility, and the wide indexes further enhance one’s ability to read the time immediately.

Grand Seiko Spring Drive Chronograph GMT Ref. SBGC253

The hour and minute hands, as well as the hour markers, have green Lumibrite, while the bezel and GMT hand have blue, achieving enhanced legibility in dark conditions. A discreet indicator next to the eight o’clock marker displays the power reserve.

Grand Seiko Spring Drive Chronograph GMT Ref. SBGC253

The case and bracelet are made of high-intensity titanium, which is about 30% lighter than stainless steel and brighter in color. The watch sits easily on the wrist, thanks to its curved lugs and low center of gravity.

The Spring Drive Chronograph GMT is water resistant up to 200 meters. The concave, textured chronograph buttons ensure better grip.

Grand Seiko Spring Drive Chronograph GMT Ref. SBGC253

The timepiece is powered by the Spring Drive Chronograph GMT Caliber 9R86. Visible on the see-through case back, this movement delivers an accuracy of ±15 seconds per month and measures elapsed time up to 12 hours. The power reserve is 72 hours when fully wound.

The bracelet features thick, H-shaped links that wrap easily around any wrist size. It has a slide adjuster to enable perfect balance on the wrist.

Grand Seiko SBGW295: Re-creation of the first Grand Seiko

Celebrating the 110th anniversary of Japan’s first wristwatch, Seiko Watch Corporation presents a re-creation of the first Grand Seiko watch. The new Grand Seiko SBGW295 model features a Brilliant Hard Titanium case and a black urushi lacquer dial with gold maki-e hour markers.

Founded in 1881 by Kintaro Hattori, Seiko produced Japan’s first wristwatch, the Laurel, in 1913. The first Grand Seiko watch was launched in 1960. This year marks the 110th anniversary of the Laurel, a milestone celebrated with the release of a series of commemorative timepieces including this new Grand Seiko limited edition.

Re-creation of the first Grand Seiko, SBGW295, Seiko Watchmaking 110th Anniversary

Grand Seiko SBGW295: With Urushi Lacquer Dial and Brilliant Hard Titanium Case

The Urushi lacquer for the dial was sourced exclusively from the country of Japan. The jet-black color of the urushi in this watch’s dial was achieved through the addition of iron. The lacquer is further enhanced through a special treatment unique to Grand Seiko that prevents its color from changing over time.

The maki-e hour markers were brought to life by urushi master Isshu Tamura in his studio in the city of Kanazawa, located on the West Coast of Japan. The seconds and minute hands are gently curved down towards the dial by hand to enhance legibility.

Re-creation of the first Grand Seiko, SBGW295, Seiko Watchmaking 110th Anniversary

Measuring 38mm diameter, the Brilliant Hard Titanium case boasts radiant Zaratsu-polished surfaces. Visible through the sapphire crystal case-back is the manually wound Caliber 9S64, which allows for the slim profile and accuracy to +5 to -3 seconds per day.

The Re-creation of the first Grand Seiko (reference SBGW295) will be provided with two leather straps. The first incorporates a traditional Japanese weaving technique called yoroiori that was once used for making samurai armour. Thin strips of calf leather and fabric are interlaced by a skilled artisan to enhance the watch strap’s durability. The second strap is leather sourced for its softness, unique texture, and comfort.

Re-creation of the first Grand Seiko, SBGW295, Seiko Watchmaking 110th Anniversary

The Grand Seiko SBGW295 watch will be available as a limited edition of 500 at the Grand Seiko Boutiques and select retail partners worldwide in February 2023.

Grand Seiko Caliber 9S 25th Anniversary Limited Editions SBGH311 & SBGR325

Japanese premium watch brand Grand Seiko celebrates the 25th anniversary of the iconic Caliber 9S with two special limited editions. The Grand Seiko 9S 25th Anniversary watches feature beautiful pattern dials inspired by the sky over Mt. Iwate.

Launched in 1998, Caliber 9S heralded a new era for the brand’s mechanical watchmaking. In the same year, the world-renowned Grand Seiko Standard was re-defined.

Since then, the Caliber 9S has been developed into a number of movement variations with different functions. Moreover, this series has been enriched with new alloys for both the main and balance springs and MEMS engineering, which allows key components to be manufactured to a tolerance of one-thousandth of a millimeter.

Grand Seiko Caliber 9S 25th Anniversary Watches

The 25th anniversary models feature the same case design and diameter as the first watch that housed the 9S movement in 1998.

Grand Seiko Caliber 9S 25th Anniversary Limited Edition, Reference SBGH311

Grand Seiko SBGH311

The first model (reference SBGH311) in the commemorative edition boasts a silver dial whose texture and color evoke the sight of the sea of clouds that cover Mt. Iwate in Iwate Prefecture, where all Grand Seiko mechanical watches are manufactured.

Grand Seiko Caliber 9S 25th Anniversary Limited Edition, Reference SBGH311

Visible through sapphire crystal case back, the Grand Seiko emblem is set into the titanium oscillating weight whose color was created especially for this watch to suggest the deep-blue sky above the sea of clouds that so often surround Mt. Iwate’s peak. This color is made possible by an anodic oxidation process.

Grand Seiko Caliber 9S 25th Anniversary Limited Edition, Reference SBGH311

Inside 37mm diameter stainless steel case beats the Hi-Beat 36000 automatic mechanical Caliber 9S85, hand-assembled in the Grand Seiko Studio Shizukuishi. It has an accuracy rate of +5 ~ -3 seconds per day and delivers a power reserve of 55 hours.

Grand Seiko Caliber 9S 25th Anniversary Limited Edition, Reference SBGH311

The Grand Seiko reference SBGH311 is a limited edition of 1,200. It will initially be exclusive to Grand Seiko Boutique Online, starting in January 2023, and then will be available at the Grand Seiko Boutiques and select retail partners worldwide in February 2023.

Grand Seiko SBGR325

The second model (reference SBGR325) in the series has a blue dial, expressing the clear and broad sky seen from the top of Mt. Iwate. Its remarkable sunray finish reflects light from every angle, creating a stunning azure backdrop for the diamond-cut hour and minute hands and indexes.

Grand Seiko Caliber 9S 25th Anniversary Limited Edition, Reference SBGR325

Just like the watch with the silver-colored dial, the seconds hand is tempered in blue and the dial features the Grand Seiko logo in a gold color commemorating the 9S movement.

Grand Seiko Caliber 9S 25th Anniversary Limited Edition, Reference SBGR325

The signature Grand Seiko blue color is realized on the oscillating weight by the same anodic oxidation process and can be enjoyed through the sapphire crystal case back.

The Grand Seiko SBGR325 watch houses the GS Caliber 9S65, which has a mean daily rate of +5 ~ -3 seconds per day and a 3-day power reserve. This reference will be available as a limited edition of 1,200 at the Grand Seiko Boutiques and select retail partners worldwide in April 2023.

Grand Seiko Kodo Constant-Force Tourbillon SLGT001 Unique Piece

Grand Seiko presents the Kodo Constant-Force Tourbillon SLGT001, a unique piece which will be auctioned in December as part of The New York Watch Auction: SEVEN at Phillips Watches.

Grand Seiko Kodo Constant-Force Tourbillon SLGT001 Unique Piece

Early this year, the Japanese premium watchmaking brand reached a new milestone with the introduction of the Grand Seiko Kodo Constant-force Tourbillon.

Its uniquely innovative movement combines a tourbillon and a constant-force mechanism as one unit on a single axis for the very first time in horological history.

Kodo is the Japanese word for heartbeat. With its unique appearance when in motion and with its carefully designed sound, this revolutionary watch reveals its vitality both audibly and visually, thanks to the open-work design and the sapphire case back.

In 2020, Grand Seiko introduced the “T0 Constant-force Tourbillon”, a concept movement incorporating a constant-force mechanism and a tourbillon as one unit on a single axis.

To bring the concept to life in a finished watch required the complete dedication of a team comprising designers, engineers, and craftsmen and women entrusted with the assembly and finishing of the movement and the case.

Each of the 340 components of the caliber was re-examined and, where necessary, re-designed and re-engineered for production. The result is Caliber 9ST1. Not only is Caliber 9ST1 smaller than its concept movement predecessor, but its high accuracy remains stable for longer thanks to the constant-force mechanism.

Furthermore, Caliber 9ST1 sets a new standard of accuracy, verified in a testing procedure during which each movement is tested for a full 48 hours in each of six positions and at three temperatures. This is twice as long as the Grand Seiko Standard.

Each movement is assessed over 34 days to verify its accuracy. When the tests are completed and this new standard has been met or exceeded, the performance characteristics of each movement are defined in the individual certificate provided with every watch.

For the Kodo model unique piece to be sold exclusively by Phillips Auction, SLGT001, the concept was based on musō 無双. Musō roughly translates to “one and only” or “second to none,” a fitting term for the unique piece exclusive to the auction.

Grand Seiko Kodo Constant-Force Tourbillon SLGT001 Unique Piece

This unparalleled model is unique in several ways compared to the global model limited to 20 pieces, reference SLGT003.

First, the multi-component case structure is made entirely of Grand Seiko’s proprietary alloy, Brilliant Hard Titanium. This material, which is used on only the outer case and outer construction of the bezel of SLGT003, is used for both the inner and exterior case components to thoroughly reduce weight and achieve a comfortable feel unique to this model.

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, allowing the Zaratsu polished surfaces to stand out more prominently.

The bridges, mainplate, and many of the components of the movement are plated in a silver color to create an entirely new aesthetic for the Kodo. A yellow-gold accent for the power reserve and seconds track of the carriage inherits the aesthetic of the T0 concept movement.

The design of the screws for the Kodo model has the appearance of the six arms of the carriages, a trait that cleverly enhances the design but also is pleasant for assembly.

The special screwdriver and screws used have an even application of torque, which the designer of T0 and Kodo, Mr. Takuma Kawauchiya, enjoys greatly. For the unique piece SLGT001, the screws are tempered blue by hand instead of being mirror polished as they are on reference SLGT003.

The carriages for the constant-force tourbillon mechanism are titanium to help reduce weight and improve efficiency. They are blue as well, which is executed through anodic oxidation.

The GS letters are specially engraved by hand on the Brilliant Hard Titanium clasp by Grand Seiko’s very best engravers. The watch comes with a calf strap specially treated in the same traditional way as was used to create the high-durability material once used in the armor of the Samurai.

Grand Seiko Kodo Constant-Force Tourbillon SLGT001 Unique Piece

The strap’s surface is painted by hand with Urushi lacquer in a multi-coating process that gives the strap a delicate sheen. It is in a brown color specially for this unique piece.

The Grand Seiko Kodo Constant-Force Tourbillon SLGT001 Unique Piece will be auctioned in the upcoming Phillips The New York Watch Auction: SEVEN on December 10-11, 2022 in New York City.

For the future owner of the unique piece Kodo SLGT001, the brand is offering an exclusive trip to Japan to meet its creators at the Grand Seiko Studio Shizukuishi.

A portion of the sale of this unique timepiece will be donated to the Children’s Heart Foundation, a leading organization dedicated to funding congenital heart defect research.

Grand Seiko Spring Drive 44GS 55th Anniversary Limited Edition, Reference SBGY009

Grand Seiko has launched a limited edition spring drive watch (reference SBGY009) to celebrate the 55th anniversary of this iconic 44GS, the first timepiece to embody the “Grand Seiko Style” design code.

The 44GS 55th Anniversary Limited Edition comes with a deep blue dial inspired by the beautiful full moon in the night sky above the Shinshu Mountains. This captivating view is visible from the Shinshu studio where all Grand Seiko Spring Drive watches are created.

Grand Seiko Spring Drive 44GS 55th Anniversary Limited Edition, Reference SBGY009

The sunray pattern on the dial catches the light at every angle and recreates the gentle sparkle that the moon casts over the landscape when it is at its very highest point in the sky. Inspired by the brightness of the full moon, the Spring Drive’s signature glide motion seconds hand and the GS letters are gold in color.

The minute and seconds hands are shaped by hand so that they curve gently down towards the minute track at the edge of the dial, enhancing the legibility of the exact time.

Grand Seiko Spring Drive 44GS 55th Anniversary Limited Edition, Reference SBGY009

Beating inside, the manual-winding Spring Drive Caliber 9R31 incorporates an innovative Dual-Spring Barrel that contains two mainsprings set in parallel and so delivers a power reserve of 72 hours.

The Grand Seiko SBGY009 (44GS 55th Anniversary) watch is a limited edition of 1,500. Each individual serial number and the words “Limited Edition” are engraved on the case back. The dark blue strap harmonizes perfectly with the rich tone of the dial.

Grand Seiko has expanded its Heritage collection by launching a limited edition model (reference SBGP017) commemorating the 55th anniversary of the iconic 44GS watch.

Introduced in 1967, 44GS was the first watch to embody the design code known as the Grand Seiko Style. Now, as part of the year-long celebration of the 55th anniversary of the 44GS, the brand presents a quartz watch that embodies the spirit of this icon.

This limited edition stainless steel watch features a remarkable light blue color dial boasting the texture of the sea of clouds that form around the mountains on some mornings in the Shinshu region where this and all Grand Seiko quartz watches are made.

Grand Seiko SBGP017 houses a specially enhanced version of Caliber 9F85 that is accurate to +5 to -5 seconds a year. The five-pointed star at the six o’clock position on the dial stands for the watch’s high accuracy.

It also has a time difference adjustment function that allows the hour hand to be moved without stopping the seconds hand, thus preserving its high precision when the wearer changes time zones. A backlash auto-adjust mechanism eliminates any shudder in the seconds hand. The date changes in the blink of an eye. A twin-pulse control system allows the minute and seconds hands to extend right to the edge of the dial so that the exact time can be read with ease.

The 40mm diameter case in steel offers the combination of Zaratsu polished and hairline finished surfaces. The fine finish of the movement with its tempered blue screws is visible through the sapphire case back.
