 Seiko Prospex the Black Series Limited Editions

The Black Series takes a fascinating step forward with a lineup of three new watches featuring a Lumibrite variant that brings a long-lasting bright green look to the hands and indexes. Because the color green is most noticeable in the dark, and because the deep gray color of the dials minimizes unwanted light reflection, these watches offer the highest degree of legibility in the dark.

In addition to their 'night vision' qualities, the watches in this series also have a water resistance of 200 meters. They feature sapphire crystal and offer a choice of designs tailored for divers and adventure seekers.

The green lumibrite colouring on the markers and hands is designed for increased visibility in the dark world of the night seas, allowing time to be read clearly in dark conditions.

Grand Seiko – KODO Constant-force Tourbillon Edition

  

SEIKO – Grand Seiko KODO Constant-force Tourbillon Platinum 950 and Brilliant Hard Titanium Edition 2022

 Grand Seiko’s first mechanical complication combines a constant-force mechanism and a tourbillon as one unit on a single axis.

Click, to see the large size. ▶ BIG FOTO

Together, the motion of the new mechanism and its unique sound give Kodo its signature heartbeat.

Today marks a new milestone in the sixty-two year history of Grand Seiko 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.

The Grand Seiko Kodo will be available as a limited edition of twenty in October 2022.

From concept to reality

In 2020, Grand Seiko introduced the “T0 Constant-force Tourbillon”, a concept movement which incorporated this patented mechanism. 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. 

Click, to see the large size. ▶ BIG FOTO

Each and every one 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. 

Click, to see the large size. ▶ BIG FOTO

Furthermore, Caliber 9ST1 sets a new standard of accuracy, in 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 and industry standard. Each movement is assessed over the course of 34 days to verify its accuracy, and 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.

From the inception of the project to the realization of Kodo in its finished form required ten years of skill, dedication and hard work.

Innovation in precision, beauty and sound

Caliber 9ST1 is complex in its engineering and design but is based on the simple insight that the integration of a constant-force mechanism and a tourbillon as one unit on a single axis would deliver practical benefits. Because there are no wheels or other components between the two mechanisms, there is no loss or change in the torque transmitted from the constant-force mechanism to the balance wheel.

 The constant-force carriage (left) and tourbillon carriage (right) are integrated together.

This leads to an increased duration of 50 hours for the constant-force mechanism and a more stable amplitude of the balance. Together, these characteristics deliver the very stable accuracy of the movement. In addition, and crucially for Grand Seiko, the volume of the movement could be reduced, allowing the aesthetics of Grand Seiko to be respected and the watch to be eminently wearable and perfectly comfortable on the wrist.

The integration of the two mechanisms allows the optimum use of space.

The integration of the two mechanisms creates a dazzling visual effect. The inner tourbillon carriage rotates smoothly as the balance steadily vibrates at 8-beats per second and the outer constant-force carriage follows its rotation at exact one-second intervals. The sounds of the escapement and of the once-per-second impulse of the constant-force mechanism harmonize with this regular visual rhythm to create, for both the eye and the ear, a deeply satisfying and re-assuring heartbeat. There is a powerful yet gentle charm to the sound that is set to a 16th note or semi-quaver which is made possible by 9ST1 being the movement with the highest frequency* ever to incorporate a constant-force mechanism.
*as of February 2022, based on Grand Seiko’s research.

Click, to see the large size. ▶ BIG FOTO

While this remarkable watch is in every way a new departure for Grand Seiko’s watchmaking, the practicality for which Grand Seiko is renowned is still fully realized in every detail. The constant-force carriage has a ruby on one of its arms, which acts as a small seconds hand. The watch incorporates a hacking function so that the rotating tourbillon carriage can be stopped when the crown is pulled out, allowing the time to be adjusted to the precise second. The hour hand has an extra facet at its tip to enhance its readability. In addition, Kodo offers 10 bar water resistance.

Light, shadow and space

Thanks to the integration of the two key mechanisms, Caliber 9ST1 has room to breathe within the case and there is sufficient space for light to penetrate, through both the front and back of the case, revealing the beauty of the hand finishing. For the same reason, the delicate interplay of light and shadow that is central to the Grand Seiko aesthetic is there to be enjoyed in the subtle shade gradations, angles and textures. Each major component is painstakingly finished by hand using a variety of techniques to endow the overall movement with the quiet yet enduring sparkle that is the hallmark of Grand Seiko.

Click, to see the large size. ▶ BIG FOTO

 The sapphire crystal case back reveals the beauty of the movement’s finishing and its intricate construction.

The case is constructed from both Platinum 950 and Grand Seiko’s Brilliant Hard Titanium to achieve a long-lasting beauty. Some case parts of both materials are Zaratsu polished and others have a hairline finish; both processes are completed by hand by highly skilled craftsmen and women to ensure that, from every angle, a visually pleasing harmony is revealed. The two case materials combine most evidently at the tapered end of the lugs where a small open space between each lug adds a lightness and unique aspect to the overall design.

 Click, to see the large size. ▶ BIG FOTO 

Grand Seiko’s expertise in hand polishing is evident in the way that the Platinum 950 and Brilliant Hard Titanium surfaces are perfectly harmonized.

Click, to see the large size. ▶ BIG FOTO

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 Samurai. The strap’s surface is painted by hand with Urushi lacquer in a multi-coating process that gives the strap a delicate sheen. The watch also comes with an alternative crocodile strap.

Grand Seiko PROSPEX 1986 Quartz Diver's 35th Anniversary Edition

SEIKO – Grand Seiko PROSPEX 1986 Quartz Diver's 35th Anniversary Limited Edition 2021

 35 years on, the classic Seiko 1986 Quartz Diver's is re-born.
Now more than ever, with the highest level of professional specifications

Click, to see the large size. ▶ BIG FOTO

In 1986, Seiko launched a diver’s watch that set a new standard. It combined Seiko’s legendary 1975 design with the 1,000 meter water resistance required for saturation diving with a quartz movement that delivered an accuracy that no mechanical diver’s watch could match. At the time, and still today, it was recognized as one of Seiko’s most important diver’s watches. Today, 35 years on, this classic Seiko Diver’s watch is re-born with new design features and upgraded professional diver’s watch specifications. This is a watch that truly lives up to the promise of the Prospex name. It will be available in July 2021 as a limited edition of 1,200 at selected Seiko Boutiques and retail partners worldwide.

This new watch inherits all the important design features and innovations which made both the 1975 mechanical and the 1986 quartz original so greatly trusted by the professional diving community. It has the 1,000m water resistance and helium resistance that saturation diving requires and incorporates the unique one-piece titanium case with its outer protector structure that makes its shock resistance so exceptional. It also has the accordion-style strap that ensures that the watch remains tight on the wrist at every depth. The outer protector is made of zirconia ceramic, which is seven times harder than steel, further enhancing its resistance to shock. The strap is now of high grade, strong yet flexible silicone.

As a new safety and design feature, the crown is marked with a vivid yellow “Lock” sign and an arrow to indicate the rotating direction. The winding stem is also in yellow so that the wearer can immediately notice if the crown is unlocked. The white hour markers stand out against the dark dial so that they are easy to read at depth.

The watch is offered with extra-strength silicone straps in both black and blue-gray, ensuring wearability both on a wetsuit and directly on the wrist. Each strap features the text “FOR SATURATION DIVING 1000m” in yellow.

The watch is equipped with Seiko’s tried and trusted quartz Caliber 7C46 which delivers a high level of torque so that it can move the powerful hands that are wide, robust and Lumibrite-coated for maximum legibility. It also delivers a reassuringly long battery life of 5 years.

SEIKO – Grand Seiko Sports Spring Drive Chronograph GMT 140th Anniversary Edition

 SEIKO – Grand Seiko SPORT Spring Drive Chronograph GMT 140th Anniversary Limited Edition SBGC240

Click, to see the large size. ▶ BIG FOTO

 A new Spring Drive Chronograph with gold highlights joins the Grand Seiko Sport Collection.

Kintaro Hattori founded his company in 1881 and led it until his death at the age of 73 in 1934. His credo was that his company should be “Always one step ahead of the rest” and, while it was not created until 1960, nothing better expresses the power of his vision than Grand Seiko with its unique design, leading edge manufacturing and exquisite finishing.  

Click, to see the large size. ▶ BIG FOTO

In honor of the 140th anniversary of the foundation of the company, Grand Seiko proudly announces a new Spring Drive chronograph that perfectly embodies Kintaro Hattori’s vision.

Zirconia ceramic, 18k gold and a refined new look

This powerful watch allies all the high functionality of the Spring Drive chronograph Caliber 9R86 with a new design and a new combination of materials. The result is a timepiece of rare refinement. The bezel catches the eye immediately with its dodecahedron shape, its zirconia ceramic outer layer and 18k gold base. Thanks to this combination of materials, it is both strikingly beautiful and highly durable.

Click, to see the large size. ▶ BIG FOTO

The case, too, uses contrast to deliver a visually arresting impression. Its top surfaces have been given a hairline finish while the sides showcase the distortion-free perfection that only Zaratsu polishing can deliver. The dial is as rich as it is legible.

Click, to see the large size. ▶ BIG FOTO

The gold color hands and hour markers stand out against the pure black dial and, as the markers are aligned exactly to each apex of the twelve-edged bezel, both time of day and elapsed time can be read precisely and at a glance.

Click, to see the large size. ▶ BIG FOTO

The 18k yellow gold buttons that operate the chronograph are prominent and designed to ensure secure operation but they are also streamlined so as to look just as good when under a shirt cuff as on the sports field.

Click, to see the large size. ▶ BIG FOTO

The Grand Seiko initials in 18k gold grace the clasp of the bracelet which is affixed to the watch while an additional crocodile strap with gold color stitches is also included in its presentation case.
A chronograph of ultimate precision

Click, to see the large size. ▶ BIG FOTO

Grand Seiko’s Spring Drive chronograph may be the most precise chronograph in the world. It measures elapsed time up to twelve hours with an accuracy rate of +/- one second a day, whether the chronograph is in use or not and, thanks to the regulation system that is unique to Spring Drive, the precision remains at this high level even when the power reserve is low.

Click, to see the large size. ▶ BIG FOTO

Equally importantly, it measures time not to the nearest fraction of a second but exactly, thanks to the fact that the glide motion hands stop at the very instant that the button is pressed and not just at the nearest “tick”. The precision of its operation is ensured by column wheel and vertical clutch systems which were first used together by the company in 1969.

Click, to see the large size. ▶ BIG FOTO

Caliber 9R86 has more than 400 parts and all are made and hand assembled by the skilled craftsmen and women in the Shinshu Watch Studio in central Japan.

The watch will be available as a limited edition of 500 at Grand Seiko Boutiques and selected Grand Seiko retailers worldwide in July 2021.
