THE JAPANESE EXCELLENCE

It is on a perfectly polished surface that the play of shadows and light is best expressed, creating a subtle harmony. An interaction that is found in the traditional Japanese sliding door Shoji, in the translucency of the screens, in the finesse of the Japanese fans.

 

 

A COMPLETE AND BEAUTIFULLY FORMED MECHANICAL HI-BEAT 36000

 

In 1968, Grand Seiko introduced Japan’s first automatic 10-beat watch (61GS) to the world.

In 2009, 10-beat Caliber 9S85 surpassed the original, with high precision parts created using sophisticated modern technology assembled with skills with skills honed over the many decades of Grand Seiko’s watchmaking. 

Innovations to the precision controlling mainspring, the hairspring, and the escapement mean that the 9S Mechanical is not simply a revival of the 10-beat movement of the past, but an entirely new incarnation of this high-precision movement.

In every detail, it is faithful to the ‘Grand Seiko Style’, the embodiment of the Grand Seiko design philosophy which started with the 44GS.

The black dial creates a strong impression with its ‘Mount Iwate pattern’, a delicate and beautiful radial pattern, inspired by the many-ridged contours of the Mt. Iwate, the mountain that is visible through the windows of the Shizuku-Ishi Watch Studio where Grand Seiko mechanical watches are made. 

The delicacy, strength and beauty of the movement can be enjoyed the exhibition case back.

 

 

THE 9S85 CALIBER 

 

The challenge of making a high-beat movement is one that only a few watchmakers choose to accept. With its higher oscillation rate of ten beats per second, greater accuracy is achievable, but this increased precision comes at a price because the faster rotational speed can take its toll on the power reserve and even the longevity of the whole movement. Grand Seiko's 10 beat movement meets these challenges and delivers an accuracy of +5 to –3 seconds a day, a power reserve of 55 hours and the durability for which every Grand Seiko watch is renowned. Caliber 9S85 is the result of many years of development and of advances both in the design and manufacture of components and in the materials themselves.

 

 

THE CHALLENCE OF A 10 BEAT MOVEMENT 

 

Although the theoretical advantages of the 10 beat movement are well known, to produce a watch that is durable, reliable and precise is extremely difficult. The two main difficulties are driving time and movement durability. A rapidly oscillating balance wheel requires a lot of power from the mainspring. The mainspring must be able to supply the balance wheel with the energy it needs to move back and forth at high speed. The wound mainspring has to be able to deliver a high level of torque to be able to supply enough power to the balance wheel for long enough to ensure a high power reserve. At the same time, the escapement mechanism that transfers the oscillations from the balance wheel through to the gear wheel train has to be as durable as any other mechanical watch. A formidable challenge indeed.

 

 

- THE HAIR SPRING - 

NEW MATERIALS TO ENHANCE FUNDAMENTAL PERFORMANCE 

 

Using the experience accumulated over the 50 years of Grand Seiko’s history, a new generation of Spron alloys was developed for the hair spring, which is at the very heart of any watch movement and whose performance determines the precision of the watch over time.

After some five years of development, a new alloy, Spron 610 was created. Compared with previous alloys, Spron 610 had around twice the impact resistance, and a magnetic resistance more than three times higher.

 

 

 - THE ESCAPEMENT MECHANISM -  

MEMS TECHNOLOGY TP ENHANCE COMPONENT PRECISION

 

Precision engineering is the route to greater accuracy in every watch, but most of all in a high beat caliber. Thanks to technologies developed in-house for semiconductor manufacturing, the escape wheel and pallet fork used in Caliber 9S85 are made with a precision of one ten thousandth of a millimeter and therefore deliver greatly enhanced performance. The secret is MEMS. MEMS (Micro Electro Mechanical System) is a technology that allows these critical components to be lighter, smoother and, in the case of the escape wheel of a more intricate design. The new design of the escape wheel featured oil reservoirs at the end of each gear tooth, improving the retention of oil, on which the smooth working of the gear depends.

 

 

- THE MAINSPRING - 

INCREASED TORQUE FOR HIGH-SPEED OSCILLATION AND A LONGER POWER RESERVE

 

A 10 beat movement must have a mainspring that can ensure a high level of torque to supply the power required for the increased oscillating rate. After six years of development a new alloy, Spron 530, was developed for the mainspring.

It delivers about 6% more power than its predecessor and a power reserve of five more hours while maintaining the same degree of corrosion resistance, durability, and magnetic resistance. The new mainspring powers the Grand Seiko 10 beat movement for a remarkable 55 hours when fully wound.

 

 

WHAT MAKES THE 9S MECHANICAL SPECIAL

 

The concept of Grand Seiko was born from the desire to build the world's best watch, and the collection continues to push precision in mechanical watches to the limits of timekeeping technology.

 

As a true manufacture, Grand Seiko incorporates the latest technology alongside its breadth of craftsmanship to raise the art of watchmaking to its peak.

Who's who

HEART AND SOUL OF A REAL MANUFACTURE

 

To obtain the title of a real Watchmaking Manufacture , a watchmaking company must be able to manufacture and perfect itself, down to the smallest detail, all its components, from the designs of the movement to the polishing, until their final assembly.

 

Grand Seiko is a real Manufacture. They design, manufacture and assemble, with their master watchmakers in their own workshops in Japan, all the pieces of every single watches.

 

The beauty of a timepiece lies above all in the precision of its manufacture. Precision of the order of a thousandth of a millimeter, and a millionth of a gram for each of our components.

 

Over the years, we continue to grow while adopting our own approach to watchmaking.

 

Through rigorous work and unwavering dedication, we have been able to achieve revolutionary innovations, such as the Spring Drive movement. Our constant commitment has also earned us pioneers in the field of the Quartz watch, and achieve the highest aesthetic finesse through unique techniques, such as Zaratsu polishing.

 

 

PRECISION : THE INITIAL OBJECTIVE

 

The first Grand Seiko was unveiled in the world on December 18, 1960. This is the first model on which appears the brand Grand Seiko, positioned under the index of 12 hours.

 

This engraving marks the beginning of a long history, punctuated by innovations, pushing back all the limits previously established in terms of precision, thus pursuing the quest for the perfect watch.

 

By the end of the 1960s, Grand Seiko mechanical watches already had exceptional precision. A precision such as during the prestigious competition organized by the Geneva Observatory in 1968, our tempers are among the 7 best mechanical movements.

 

 

THREE MOVEMENTS

 

For Grand Seiko, time is measured at the rate of 3 types of movement: mechanical, quartz and Spring Drive.

The excellent of Grand Seiko begins with the choice of raw materials. The combined talents of our elite master craftsmen, coupled with state-of-the-art manufacturing technology, ensure that each timepiece is kept operating at a level of perfection.

 

Corollary of this high technological precision, the Grand Seiko style is defined by a timeless refinement, whose secret lies in an elegant and refined aesthetic.

 

 

JAPANESE AESTHETICS: THE SOURCE OF INSPIRATION

 

Fans. Screens. Wood panels and rice paper ...

In Japan, land of contrasts, an infinity of shades separate the shadow of light. According to Zen philosophy, the shadow is as important as the light, because only the shadow allows the light to express itself.

 

A simple form composed of a flat part and a curve, allows to reflect the light and to reveal infinite expressions.

 

The Grand Seiko style is based on this Japanese sense of aesthetics. A natural sophistication, inspired by the act of observation and appreciation of nature.

 

 

WHEN ELEGANCE AND FUNCTIONALITY GET PERFECTLY 

 

Each case is designed to reflect the smallest ray of light. Each facet is polished by hand, giving it this mirror-polished look. A clear, harmonious, unique aesthetic, which tells you that you have before you a Seiko Grand, attractive, pleasant to wear, perfect readability, and practical par excellence.
