The history of the only manufacture with every watchmaking expertise.
Our Heritage
EVENTS
The story of Seiko began in 1881, when a 21 year old entrepreneur, Kintaro Hattori, opened a shop selling and repairing watches and clocks in central Tokyo. Just eleven years later, in 1892, he established the 'Seikosha' factory.
1881
EVENTS
In 1892 Kintaro Hattori bought a disused factory in Tokyo and Seikosha was formed (In Japanese, "Seiko" means "exquisite", "minute" or "success" and "sha" means house). It was here that Kintaro Hattori produced his first clocks and these marked the beginnings of a company that was to become one of the world's most important manufacturers of timepieces.
1892
MILESTONE MODELS
Throughout the 1890's, the success of Seikosha's wall clock business increased, and Kintaro looked to broaden the range of his business. In 1895, he created a pocket watch, the Timekeeper. It was a vital step forward, without which the future of Seiko would have been very different as it paved the way for Japan's first ever wrist watch.
1895
MILESTONE MODELS
In the beginning of the Taisho Era, pocket watches were still very popular and there were only a few wristwatches imported to Japan. Kintaro, however, was determined to be 'one step ahead' and embarked on the arduous task of creating Japan's first ever wristwatch. In 1913, he succeeded and the Laurel was produced. In the early days, the company was able to produce only 30 to 50 watches a day, but, for the first time, Kintaro had established a lead on the rest.
1913
MILESTONE MODELS
In 1923, the Great Kanto Earthquake struck and the company's headquarters and the Seikosha factory all burned down. A fresh start had to be made. Just after the Earthquake, the company had created a new watch and it went on sale in December 1924.
It was the first to carry the name Seiko, introducing to the world for the first time the brand name that was later to become synonymous with precision and accuracy, innovation and refinement.
1924
1929. As its railway network expanded, Japan National Railways appointed Seiko as its official supplier. Train drivers often made wooden cut-outs on their consoles where the approved pocket watch would sit in line of sight as they drove their trains.
1929
EVENTS
The Wako store in central Tokyo opens with the now familiar clock tower on its roof. Built in the neo-classical style, it remains one of Tokyo’s most famous buildings.
1932
Diashock is a shock-resistance device. When a watch is subject to shock, as when it is dropped on a hard floor, the component most likely to be damaged is the balance-staff pivot, which is the balance wheel’s rotation axis. Even compared to other movement parts, this part is extremely thin, being only between 0.07 to 0.08mm in diameter, or about the same as a human hair.
Protection from shock is therefore crucial and the Seiko solution was to create Diashock, a device that absorbs impact. Diashock also reduces friction to ensure optimum amplitude of the balance wheel.
1958
MILESTONE MODELS
This is the first self-winding watch equipped with Seiko's proprietary Magic Lever system. The Magic Lever is an innovative self-winding mechanism that uses the simple “claw lever system” efficiently to transmit the power of the oscillating weight in both directions.
The Magic Lever is still used in many Seiko automatic watches. Thanks to the simplicity of its design and its efficiency in energy generation, it remains one of Seiko’s most durable and important contributions to the progress of the automatic watch.
1959
MILESTONE MODELS
In 1960, the first Grand Seiko model was produced. High in the mountains in Nagano prefecture in central Japan, a small team of Seiko's most experienced and skilled watchmakers were entrusted with the task of making the very best watch of which they were capable. Grand Seiko was to represent the pinnacle of Seiko's excellence in mechanical watchmaking and to deliver more accuracy, legibility and durability than any other watch.
1960
EVENTS
The day the Tokyo Olympic games opened, Seiko was ready with 1,278 timing devices, all purpose built for the task. The stopwatches created for athletics were tested by Mr. Paulen, later President of the IAAF.
After an hour of testing, two stopwatches registered less than 1/10 second of difference.
Thanks to a new heart-shaped cam on the balance, a new level of accuracy had been achieved. Seiko had passed the test with flying colors.
1964
MILESTONE MODELS
Japan’s first chronograph was introduced in 1964, the year of the Tokyo Olympic Games. Its smooth operation and durability were ensured by a column wheel.
1964
MILESTONE MODELS
The first Japan-made diver's watch, water resistant to a depth of 150 meters. The winding crown was designed with a double packing structure to withstand high water pressure. Designated for use by the 8th Japanese Antarctic Research Expedition.
1965
EVENTS
From 1963, Seiko participated in the Neuchâtel chronometer competition. In 1967, Seiko was awarded second and third places. This was the last year of the competition.
Seiko then entered the Geneva Observatory Competition in 1968 and, at the very first attempt, achieved a remarkable result. Seiko’s entries were awarded every place from fourth to tenth, achieving an all-time record for mechanical movements.
1967
WORLD'S FIRSTS MILESTONE MODELS
As the world's first automatic chronograph with a 'Magic Lever', column wheel and vertical clutch, it was a milestone in Seiko's journey toward pre-eminence in chronograph technology.
1969
WORLD'S FIRSTS MILESTONE MODELS
The world’s first quartz watch, the Seiko Quartz Astron, was introduced in Tokyo on December 25, 1969. It delivered unmatched performance. It was accurate to within 5 seconds per month, 100 times more accurate than any other watch, and it ran continuously for a year, or 250 times longer than most mechanical watches. The quartz revolution had begun.
1969
WORLD'S FIRSTS MILESTONE MODELS
This fully-electronic watch used the world's first six-digit liquid-crystal display to indicate the time. Capable of continuously displaying the hour, minutes and seconds on a field-effect liquid crystal display, this groundbreaking digital watch attracted wide attention when it was first marketed in October 1973.
The internally developed LCD was long-lived (50,000 hours) and had good contrast. A lamp provided enough illumination to make the numbers on the display easy to read even in the dark.
1973
WORLD'S FIRSTS MILESTONE MODELS
In 1975 Seiko launched the world's first digital quartz watch with a chronograph, the 0634. It could record time to 1/10 of a second and had a lap time function. It also incorporated an internal light, so that it could be seen clearly in the dark. It became a huge hit and created the market for high-function digital watches.
1975
WORLD'S FIRSTS MILESTONE MODELS
One day in 1968, Seiko's engineers received a letter from a professional diver from Hiroshima Prefecture. The letter shocked Seiko's engineers with its vivid description of the stresses and strains put on a watch by professional saturation divers who dive to depths of 350 meters. Seiko took up the challenge. After seven years of research, the Professional Diver's 600m, the world's first diver's watch with a titanium case, was created. It incorporates a gasket making it impervious to helium and legible at great depths. It set a new standard for diver's watches.
1975

Ten years after the world’s first six-digit LCD watch, Seiko introduced a watch with a voice recording function, another world first.
8 seconds of sound could be recorded and then replayed on demand. It also had a voice alert at pre-set times.
1983
WORLD'S FIRSTS MILESTONE MODELS
Seiko's mastery of quartz technology and of mechanical chronograph watchmaking came together in the creation of the world's first analog quartz chronograph. It measured elapsed time to 5/100 second and offered split time capability and a tachymeter. It was designed by the celebrated Italian car designer, Giorgetto Giugiaro.
1983
WORLD'S FIRSTS MILESTONE MODELS
After introducing the world's first TV watch, Seiko introduced a wrist computer that stored data. It was the first of its kind. It had a memory of up to 2,000 characters and could store telephone numbers and addresses as well as a diary or schedule for up to one month. The Seiko wrist computer marked the beginning of the age of portable information devices.
1984
WORLD'S FIRSTS MILESTONE MODELS
The Diver's 1000m was the first watch to use ceramic material for the outer case layer. The lightweight, corrosion resistant titanium inner case with a remarkable one-piece structure enabled this watch to withstand depths of 1,000 m.

Like all Spring Drive calibers, the one that powers this Credor Sonnerie is completely silent and so allows the wearer to enjoy to the full the long, lingering chime of the traditional Orin bell that is incorporated in the case.
2006
Thanks to its glide motion hands, only the Spring Drive Chronograph can measure elapsed time exactly, and not to the nearest fraction of a second. It redefines the accuracy of the spring-driven chronograph by offering one-second-a-day precision.
2007
MILESTONE MODELS
This hi-beat caliber beats at ten times a second. While the faster vibration rate makes a watch more resilient to shock and thus more accurate, it also consumes more power from the mainspring and demands greater resiliency from other components.
Grand Seiko's 10 beat movement 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.
This 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 search for totally precise time, everywhere on the planet, ended with the introduction of the Seiko Astron GPS Solar. By developing in-house a patented, low-energy-consumption GPS receiver, Seiko created a watch that receives GPS signals and identifies the time zone, time and date data using the global network of GPS satellites. It recognizes all the 39 time zones on earth. This breakthrough timepiece was called Seiko Astron. Like its celebrated 1969 predecessor which was the world’s first quartz watch, the new Seiko Astron ushered in a new age of timekeeping technology.
2012
EVENTS
When, in 1913, Seiko built its first wrist watch, the company’s president called it the Laurel. It was not only a first for Seiko, but also a first for Japan and it was the beginning of a tradition of innovation that resulted directly from Kintaro Hattori’s determination that Seiko would always be “one step ahead of the rest”.
2013
Astron GPS Solar had been an outstanding success since its launch in September 2012, with its huge global acceptance giving proof positive of the global demand for a watch that adjusts to time zones. This new Astron caliber offered four new features, designed to attract new consumers to the fast-growing world of Astron.
Seiko Astron GPS Solar Chronograph
Chronograph: The new caliber offers a 6 hour chronograph whose operation could not be more simple.
Smaller: The new case size is 30% smaller, and the watches' dimensions (44.6mm x 13.3mm) are now the same as most mainstream multi-function watches.
This new size, which opens out many new design possibilities, has been achieved by a new advance in Astron's energy-saving technology which allows the watch to connect to the GPS network with a smaller antenna.
Easier: The simple 'one-touch' operation of the GPS function has not changed; just press one button for six seconds and Astron's GPS function is activated.
However, the secondary functions (manual time zone selection etc) have been made more accessible and more intuitive thanks to the new electronic setting function of the crown.
More colors: The classic Astron black dial is available in the new design, but new color dials are now possible, thanks to a new dial with extremely high light penetration capacity.
