Grand Seiko – SPORT Collection SLGC009 Tokyo Lion Tentagraph Titanium 2025

The Grand Seiko Tentagraph movement is introduced in the Tokyo Lion design, created for high performance in any sporting situation.

In 2019, Grand Seiko created a new sports watch inspired by the lion, an enduring symbol from its earliest days in 1960. The new series brought a distinctive edge to Grand Seiko sports watches with its sharp angularity and bold case design.  Today marks a new milestone for Grand Seiko as it pioneers the Tokyo Lion sports watch into a new era with a powerful yet refined design and high performance courtesy of its first mechanical chronograph movement, the Tentagraph.

A powerful symbol of excellence and determination

The lion symbol reflected the aim of the original Grand Seiko team to create the very best timepiece they could in terms of accuracy, durability, and beauty. Inheriting the lion symbol, this watch was developed in the relentless pursuit to advance the essence of the Grand Seiko sports watch.

From its case design rich with symbolism to its refined rubber strap and textured dial, numerous aspects have evolved from previous lion-themed timepieces in pursuit of key sports watch values such as legibility, durability, comfort, and beauty.

A design that pursues the essence of a sports watch

This watch marks the first time that Grand Seiko’s Brilliant Hard Titanium has been adopted in the Sport Collection. The alloy is brighter than traditional titanium, causing the case’s hairline finished and Zaratsu-polished surfaces to appear even more radiant, enhancing the strong design. Brilliant Hard Titanium makes the watch not only light but also highly resistant to corrosion and scratches while commanding a surface hardness double that of standard stainless steel.

On the side, the pushers have been updated to improve the chronograph function’s ease of use. The powerful design of these buttons was created to achieve a satisfying feeling when engaging the chronograph.

The new creation also features a dial pattern that takes inspiration from the mane of the lion as it waves in the wind. At the 3, 6, and 9 o’clock positions, there are distinctive, three-dimensional sub-dials, which are inlaid onto the dial. Thanks to these three-dimensional sub-dials, the distance between the sub-dial markings and hands has been reduced, leading to enhanced legibility.

Resembling the sharp claws of a lion, the diamond-cut indexes of the main dial reflect light beautifully. Moreover, these indexes have been made taller and shaped to hold sufficient Lumibrite for improved readability in any light condition.

Designed for wearing comfort 

The newly developed rubber strap has a tensile strength of nearly 2.7 times the typical silicone strap used for Grand Seiko. It was created for this watch, and its brown color pairs perfectly with the patterned dial. Not only does the strap have an excellent texture, but the motif on the back was inspired by the lion’s paw, providing a playful design detail even if it is only visible to the wearer. Combined with the slightly curved case back, the new strap ensures comfort and stability on the wrist befitting a Grand Seiko sports watch.

Just like every Grand Seiko creation, the pursuit of precision is at the heart of the Tentagraph movement. Caliber 9SC5 beats 10 times per second, ensuring a high level of accuracy when measuring elapsed time as well as the time of day.

And, thanks to its energy-efficient Dual Impulse Escapement and two barrels, the watch runs for three days even when the chronograph is in operation. Furthermore, each Tentagraph is tested for 20 days, three days longer than most Grand Seiko mechanical movements, to ensure that it meets the Grand Seiko Standard of +5 to -3 seconds per day even when the chronograph is running.

Third was the introduction of the Grand Seiko Free-Sprung Balance and overcoil. This overcoil helps improve the concentricity of the shape of the hairspring during oscillation across positions. At the same time, the free-sprung balance ensures a more stable precision long-term and higher shock resistance than a watch using a regulator. It allows for adjustments of the rate via the meantime screws on the balance, but also the beat error can be adjusted thanks to a rotatable stud affixed to the end of the uniquely shaped overcoil, which was determined after 80,000 simulations and utilized the data of the varying shapes to allow for this adjustment never before possible in a free-sprung balance.

Most importantly, in the introduction of the 9SA5, the new and innovative Dual-Impulse Escapement was introduced. This escapement was developed to improve the efficiency of energy delivery from the two barrels through the gear train and delivered to the balance wheel. Much like a conventional lever escapement, the Dual-Impulse Escapement indirectly delivers power to the balance via the sliding action of the escape wheel across the impulse plane of the pallet jewel through the pallet fork and to the impulse pin attached to the balance staff.

However, more uniquely, the escapement also delivers energy directly to the balance, similar to a detent escapement, where the escape wheel propels the balance wheel via the teeth of the escape wheel, directly colliding with a jewel attached to the side of the balance roller, allowing for the direct delivery of energy. This new escapement provides an efficiency approximately 20% greater than that of the already highly efficient 9S85 calibre, which uses a lever escapement that is improved via components manufactured with MEMS.

MEMS allows for parts with more intricate designs, which reduces weight, enhances friction resistance due to smoother surfaces, and even adds a lubricant retention step on each tooth to preserve lubricant over a longer course of time. Naturally, the MEMS manufacturing method is also applied to the Dual-Impulse Escapement of calibre 9SA5, and though their designs are dramatically different, all those same benefits are still applied.

It is important to understand the details of the Calibre 9SA5 to understand how Grand Seiko could potentially introduce a mechanical chronograph. It could have been assumed many years ago that if Grand Seiko were to create this type of calibre, it would have to be Hi-Beat 36000 due to the high stability and precision attainable with this frequency. But the key breakthrough, possibly unknown at the time, would be the introduction of the new Dual-Impulse Escapement, allowing for an incredibly high energy transmission efficiency.

Hallmarks of a high-quality modern chronograph, a vertical clutch and a column wheel ensure high accuracy and operability. The vertical clutch eliminates any shuddering or jumping of the hands when the chronograph is engaged and enhances measurement accuracy, while the column wheel delivers precise control of the chronograph operation. The movement incorporates a three-pointed hammer, which ensures that, when the reset pusher is pressed, the hands return to zero instantly and in perfect synchronization.

Grand Seiko – MASTERPIECE Spring Drive 8 Days Days Jewelry Edition

 

SEIKO – Grand Seiko – MASTERPIECE Spring Drive 8 Days Jewelry White Lion Platinum Exclusive Limited Edition 

Click, to see the large size. ▶ BIG FOTO 

The white lion inspires a Grand Seiko jewelry timepiece of rare craftsmanship.

When, in 2020, Grand Seiko introduced a jewelry watch into the Masterpiece Collection for the first time, its design evoked the landscape of the region where it was created. Today sees the introduction of another Spring Drive jewelry timepiece whose craftsmanship is of the same high standard but whose inspiration is very different. Since 1960, the lion has symbolized the strength of Grand Seiko but now it finds a new expression. The white lion has arrived.

Click, to see the large size. ▶ BIG FOTO 

The strength and power of the lion are still at the heart of this watch but the white lion has a beauty that is as striking as it is rare. Sparkling diamonds, black spinels, white gold and Platinum 950 combine to create a stunning timepiece of exquisite artistry. 

The lion’s mane flows across the dial

While the strong and angular lugs speak of the power of the lion and the graceful tresses of its mane are reflected in the pattern on the dial, it is the jewels that attract the eye.

112 diamonds are embedded in the upper surfaces of the case and a further 60 baguette diamonds surround the dial on the bezel. 

Click, to see the large size. ▶ BIG FOTO 

No fewer than 94 diamonds are set in the dial, contrasting with the 26 black spinels to create a stunningly intricate effect. 

Click, to see the large size. ▶ BIG FOTO 

The seconds hand is tempered to a perfect grey color to match the overall tone and a single brilliant-cut diamond is set into the crown.

Hand craftsmanship of the highest order

On the dial, the carefully selected spinels and baguette diamonds are tapered and serve as minute and hour markers. All these gems are set by hand between a very thin pair of 18k white gold rails by the most skilled of the jewelry craftsmen and women in the Shinshu Watch Studio in Shiojiri. 

Click, to see the large size. ▶ BIG FOTO 

The diamonds on the bezel are also set by hand with a precision that allows the light on their table surfaces to flow evenly, as if the bezel were a single surface. The same high level of jewelry expertise is to be seen on the lugs where the diamonds are set so exactly that they also seem to create a single, flat surface.

A Spring Drive movement with eight days of power and a view of Mt. Fuji

The watch is powered by the Spring Drive 8-day Caliber 9R01 which was created by the Micro Artist Studio, the elite team of watchmakers who create all the Spring Drive watches in the Masterpiece Collection and whose home is in the same Shiojiri facility as the Shinshu Watch Studio.

It incorporates three barrels arranged in sequence to deliver the extended power reserve which is shown by an indicator visible through the sapphire crystal case back along with the exquisite finishing of the one-piece bridge, designed in the image of Mt. Fuji.

A new jewelry Masterpiece inspired by the strenght and beauty of the White Lion

Grand Seiko’s jewelry masterpieces are produced in Shiojiri, where the skilled craftsmen and women of the Micro Artist Studio have been making Spring Drive masterpieces since 2000, combining the best of horological innovation and traditional hand craftsmanship.

Today at Watches and Wonders, Grand Seiko announces reference SBGD209, the newest entry to the Masterpiece Collection, this time inspired by the majestic white lion.

Click, to see the large size. ▶ BIG FOTO 

The lion has long been emblematic of Grand Seiko. The king of the jungle made its debut on the case back of the first-ever Grand Seiko timepiece in 1960, and it has remained the enduring symbol of the brand. The choice of the lion as the brand’s icon reflected the ambition of the Grand Seiko team to make the best timepieces of which they were capable—what they would describe as the “king of watches.”

Click, to see the large size. ▶ BIG FOTO  

Rendered in Platinum 950, the “Tokyo Lion” case of SBGD209 features a strong, angular design with numerous facets throughout. It measures 44.5mm in diameter and 14.4mm in thickness. Despite the size and angularity of the design, the case features a gentle curve along its underside that allows for a comfortable fit on the wrist. Its sharply defined edges and prominent ridges are made possible by first cold forging the alloy and then implementing a unique adaptation of Zaratsu polishing technique developed specifically for Platinum 950.

While the mid-case shape speaks to the lion’s power, it is the elegant application of the fine stones that attract the eye. One hundred twelve diamonds are fixed to the outer surfaces of the case, and an additional 60 baguette diamonds are applied to the bezel.

The diamonds on the bezel are set by hand with a precision that allows the light on the surface to flow evenly as if the bezel were a single surface. The same high level of craft is applied to the lugs, where the diamonds are set so precisely that they also appear to create a single flat surface. A brilliant-cut diamond is set into the crown.

Click, to see the large size. ▶ BIG FOTO 

The dial bears a pattern representing the mane of the lion, and here it is rendered in white. Carefully selected black spinels and baguette diamonds are tapered and serve as minute and hour markers. These gems are meticulously set by hand between a very thin pair of 18k white gold rails by the most skilled craftspeople from the Shinshu Watch Studio’s jewelry studio. Contrasting against the dial base for a highly legible display are bold hands, and the seconds hand is tempered to a perfect grey color to match the overall tone of the dial.

Click, to see the large size. ▶ BIG FOTO Powering the watch is caliber 9R01. This Spring Drive movement, produced by a dedicated team at the Micro Artist Studio, offers an accuracy of 10 seconds per month and an eight-day power reserve. 

Click, to see the large size. ▶ BIG FOTO 

The architecture and finishing of the movement are inspired by the scenery as seen from the Takabochi Highlands, near the Micro Artist Studio: the bridge traces the contours of Mt. Fuji, the glide wheel evokes the rising sun, the rubies and tempered blued screws recall the lights of Suwa City at night, and the power reserve indicator marks the shape of Lake Suwa. The caliber features convex beveling along the bridge’s edges, and the top surface has a fine hairline finish—both details executed entirely by hand.

SBGD209 will be offered in a limited edition of just five and will be presented at selected Grand Seiko Boutiques in May 2022 for $250,000.

Grand Seiko – ELEGANCE Spring Drive GS9 Club USA Exclusive Edition

  

SEIKO – Grand Seiko – ELEGANCE Spring Drive Manual GS9 Club USA Exclusive Limited Edition 2022

 A GS9 Club USA exclusive inspired by Matsumoto Castle at dusk in autumn

Click, to see the large size. ▶ BIG FOTO  The GS9 Club USA 2022 Limited Edition draws inspiration from Shinshu, the area of Japan where all Grand Seiko Spring Drive watches are crafted. In Showa 9 (the ninth year of the Showa era, approximately 1934), a woodblock print, done in the style known as ukiyo-e, was created depicting the famed Matsumoto Castle of Shinshu.

 Click, to see the large size. ▶ BIG FOTO 

The warm grey tone of theGS9 Club USA Limited Edition was chosen to pay tribute to Matsumoto Castle at dusk in Autumn. The kirazuri dial pattern, which adorned the first USA exclusive models in 2018, was selected as a tribute to these first USA exclusives and the ukiyo-e woodblock print depicting Matsumoto Castle. The term kirazuri translates roughly to “sparkling painting” and refers to a technique of sprinkling mica powder on ukiyo-e prints to create an exquisite sparkle. This dial features the sparkling kirazuri pattern at its center, with the minutes track finished to contrast with the centerpiece of the dial.

Click, to see the large size. ▶ BIG FOTO 

The dial is curved to follow the shape of the crystal, and the minutes and seconds hands are curved by hand to create high legibility and to follow the contour of the dial and crystal. The seconds hand is individually tempered blue, and the remaining hands and markers are multi-faceted and diamond-cut to enhance beauty and legibility. To create a pure and highly legible dial, the power reserve indicator is visible through the sapphire caseback.

 Click, to see the large size. ▶ BIG FOTO  

The thin profile Elegance Collection “thin-dress series” design was selected for its 38.5mm diameter and slimness of 10.2mm. A dramatically dual-curved sapphire crystal that follows the curvature of the case lugs and a short case length create wearability and a sense of comfort that is versatile for daily wear.

Click, to see the large size. ▶ BIG FOTO 

The slim Spring Drive caliber 9R31 was chosen for its precision, robustness, long duration, compact size, and beautiful aesthetic with its tempered blue screws and delicate hairline finish. The innovative movement uses a Dual–Spring barrel with mainsprings set in parallel within a single barrel that winds and unwinds simultaneously, achieving a 72-hour duration in a compact size.

The single-piece bridge enhances rigidity, while the hairline finish creates a beautiful contrast of light and shadow when paired with the mirror-polished edges of the openings.

Grand Seiko – KODO Constant-force Tourbillon Unique Piece

  

SEIKO – Grand Seiko KODO Constant-force Tourbillon Brilliant Hard Titanium - Unique Piece 2022

 

 A Unique Heartbeat: The Piece-Unique Grand Seiko 
Kodo Constant-Force Tourbillon SLGT001

Grand Seiko reached a new milestone in its sixty-two-year history with the introduction of the brand’s first mechanical complication watch, the Grand Seiko Kodo Constant-force Tourbillon. At its heart is a uniquely innovative movement that delivers a level of stable accuracy unprecedented for Grand Seiko by combining a tourbillon and a constant-force mechanism as one unit on a single axis for the very first time in horological history. 

  Click, to see the large size. ▶ BIG FOTO

The watch is named Kodo, 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. Most remarkable of all is the way that the constant-force mechanism and the tourbillon have been integrated together to allow the creation of an overall design that is perfectly in harmony with the values of Grand Seiko and whose technical ingenuity is encased in a watch of great elegance and wearability.

  Click, to see the large size. ▶ BIG FOTO 

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. 

Click, to see the large size. ▶ BIG FOTO

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.

Click, to see the large size. ▶ BIG FOTO 

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

Click, to see the large size. ▶ BIG FOTO

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.

  Click, to see the large size. ▶ BIG FOTO 

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. Anodic Oxidation is a surface treatment in which the titanium carriages are subjected to electrolysis to generate an oxide film artificially. Titanium oxide film produces color according to the light refraction index, enabling the production of different colors by varying the thickness of the oxide film. This once again emulates the styling of the original concept T0.

The GS letters are specially engraved by hand on the Brilliant Hard Titanium clasp by Grand Seiko’s very best engravers. The watch is offered 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. 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.

Accompanying the unique piece Kodo SLGT001, will be an exclusive trip to Japan to meet its creators, the Grand Seiko team, a visit to Grand Seiko Studio Shizukuishi in the lovely Iwate prefecture.
