THE JAPANESE EXCELLENCE

  • A PROFESSIONAL DIVER’S WATCH, MADE THE GRAND SEIKO WAY

This professional diver's model features Caliber 9S85 which has a precision of +5 to -3 a day. It is built to withstand pressures encountered in saturation diving, down to a depth of 600 meters. 

 

The grooves on the rotating bezel ensure a firm grip even with thick diving gloves. Luminous markers at every ten second point on the dial ensure the legibility on which the safety of the deep sea diver depends.

Every component is built to last, but all divers know that their watch needs regular maintenance, just like every other device on which his or her life may depend. This is why the case, stem and crown are designed for secure servicing and even the bezel has a four-part design that makes for easy disassembly and re-assembly.

 

The dial is made of pure iron in order to protect the movement from the harmful effects of magnetism. It delivers safe and secure use during diving and, thanks to the lightness of the titanium, every-day usability is also assured. 

 

It has the distinctive clean edges and distortion-free mirror surfaces that only Zaratsu polishing can deliver.

 

  • THE CONCEPT ? PUSCHING BACK BOUNDARIES !

This model is the Grand Seiko's first mechanical diver's watch for saturation diving.

Designed to meet the most demanding challenges on earth, Grand Seiko’s Professional Diver’s watch combines both high accuracy and the reliability that the serious diver requires. It is designed for saturation diving to a depth of 600m.

 

With a titanium case, exceptional anti-magnetism, a high beat movement, a 55 hour power reserve and a construction that is designed to defy the elements, this is a watch that pushes back the boundaries of what a diver’s watch can deliver.

 

  • FORM AND FUNCTION IN HARMONY 

With a distinctive clean edges appearing in a complex polyhedron and a distortion-free mirror surface created by our experts using Zaratsu polishing. The case has the beauAll the characteristics of the aesthetics of Grand Seiko are here. The distinctive clean edges and distortion-free mirror surfaces that only Zaratsu polishing can achieve, the supreme legibility that does justice to the precision of the movement and the durability that only a true, vertically integrated manufacturer can deliver. As soon as you see this watch, you know that it is Grand Seiko.

 

  • THE ONE-WAY ROTATING BEZEL, PERFECTED

The grooves on the rotating bezel ensure a firm grip even with thick diving gloves. The bezel has excellent operability with a unique non-slip knurled finish. Each groove is carefully finished, making it easy to grip, but polished to be pleasing to the eye. Luminous markers at every ten seconds ensure the legibility that brings safety to the deep sea diver.

 

  • ENHANCED ANTI-MAGNETISM

The dial is made of pure iron in order to protect the movement from the harmful effects of magnetism and delivers magnetic resistance of 16,000 A/m. In addition to safe and secure use during diving, every-day usability is also assured.

 

  • COMPONENTS, BUILT FOR A LONG-TERM USE (photo profil)

Every component is built to last, but all divers know that their watch needs regular maintenance, just like every other device on which his or her life may depend. This is why even the case, stem and crown are designed for secure servicing and even the bezel has a four-part design that makes for easy disassembly and re-assembly.

 

  • A BRACELET DESGINED EXPRESSLY FOR DIVING (photo bracelet)

The bracelet has a sliding extension setting to accommodate pressure changes. Moreover, the use of high intensity titanium allows the links to be thick, strong and corrosion resistant while still light and easy to wear.

 

  • THE CALIBER 9S85 : THE WORK OF A TRUE MANUFACTURER 

The 9S85 high beat movement is designed, made, assembled, adjusted and tested at the Shizuku-Ishi Watch Studio. This remarkable facility is home to all Grand Seiko mechanical watch production.

 

Each movement is tested individually before being built into its case and protected by the L-shaped seals that the company invented to ensure impermeability to dust, water and helium gas.

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.
