Seiko in Number

Cal.290
the Mechaniucal Caliber with SEIKO’s Original “Magic Lever” for Self-winding Watches was launched in 1959
In 1959 the “Magic lever” was developed by SEIKO and became the heart of the Gyro Marvel self-winding watch containing Cal.290.This vital component efficiently transforms the movement of oscillating weight into the energy that drives the watch.
No matter which way the weight swings, it is turned into the one-way rotation that winds the mainspring. For nearly 50 years it has prevailed in our markets, and the technology is also at the SEIKO Spring drive launched in 2005.

1/400
The QC-951 Crystal Chronometer, reduced to 1/400th , the Size of two Filing Cabinets previously required QC-951 was the first quartz chronometer to be reduced to 1/400th of the size of two filing cabinets previously required. Intended for the Tokyo Olympic Games in 1964, and exhibited at observatory competitions during the course of its development, it was the first portable quartz timekeeper created by SEIKO. 1964 was, therefore, the year when highly accurate timekeeping became a practical reality in daily life.

1278
All 1,278 SEIKO Stopwatches performed impeccably at the Tokyo Olympic Games
1,278 is the number of stopwatches and other timekeeping devices supplied by SEIKO for the Tokyo Olympic Games in 1964. The enthusiasm and dedication of SEIKO engineers ensured their performance without a single timing error and laid the groundwork for SEIKO’s later remarkable advances.

6425
ISO6425 (Divers’ watches), an International Standard of Divers’ Watches, has been developed based on SEIKO’s Model
SEIKO has been continuing research and development of divers’ watches since SEIKO’s first divers’ watches was released in 1965, and it is trusted worldwide by discerning divers as being the most reliable.

SEIKO dominated the Geneva Observatory Competition in 1968 by obtaining the Highest ever Point SEIKO was awarded the “best mechanical wrist chronometer” in Geneva.
The score was the record high in the history of the competition. The competition. The competition regulators also attained record scores. This feat has solidified SEIKO’s leading in position in the industry.

1969
The SEIKO Astron, the world’s First Quartz Watch, was launched in 1969
1969 was the year when the SEIKO Astron, the world’s first quartz watch, went on sale.
The accuracy previously sought only in observatory competitions was now within the reach of everybody .It is one of the most epoch-making products in SEIKO’s entire history. It was given the IEEE milestone award in 2004.The design of the SEIKO quartz watch is now the standard for the industry. The technology and devices developed along the way have had much broader applications in product as varied as mobile phones, computer and even digital cameras.

1986
Kinetic debuted at Basel in 1986
Since then, Kinetic has been one of SEIKO’s platform calibers along with Mechanical and and Quartz and at the same time it has been very important basis for developing SEIKO’s world leading Spring Drive technology.


60000
SEIKO’s Kinetic Generator is revving up 60,000 rpm
60,000 rpm is how revolutions the rotor of the generator driven by the oscillating weight in the Kinetic watches has to make per minute. It’s turning far faster than the 4,000 to 20,000 rpm of a Formular 1 racing-car engine.

Delicate, Positive Adjustments in 0ne
SEIKO’s proprietary three-pointed hammer, a one-layered piece, resets all three hands of the mechanical chronograph 8R at once to zero. The gap between the hammer center and guide axis as well as the perfect positioning of the hammer operating lever axis are the secret of this structure impossible up to now.
