Introducing the Seiko "Chronos" made in 1959 .

 "Suwa Seikosha" and "Daini Seikosha" (Kameido Factory) were rivals to improve their technical capabilities, even though they were in the same group.
The watch "Marvel" announced by Suwa Seikosha in the chaotic period after the war boasted overwhelming popularity.

Two years later, in 1958 , the Kameido factory-made wristwatch "Chronos" was announced.

Chronos, which actively incorporated modern design from the movement to the case design, had performance that rivaled not only the Marvel, but also the Crown, one of Seiko's most famous models.

Chronos is one of the watches that proves the capabilities of the Kameido factory, such as the development of the later "King Seiko".


Chronos has a soft impression by using many curves.
It gives the impression that the design of a pocket watch has been reduced to the size of a wristwatch, and it is a design that is unique to the Kameido factory, which was good at developing pocket watches.

The case is made of 14- karat gold-plated material, but the indexes are made of solid gold, so the way they age and shine is different, giving them a tasteful impression.

By omitting decorations as much as possible and arranging a simple silver dial, the design makes the most of this gold hue.

Equipped with a 23 jewel manual winding movement.
It is generally said that it is difficult to make a thin movement, but we succeeded in making this movement with a thickness of 4 mm while maintaining accuracy.

It is equipped with an anti-seismic device from the initial model, and has performance that surpasses Marvel's movement in terms of accuracy, maintainability, and practicality.


The size is length: 42,3mm , width: 37mm , thickness: 9,9mm .
At that time, the thin type was the mainstream, and the thickness was less than 1 cm .

Although it looks voluminous, it is lightweight and does not get caught on the hem of a suit or jacket, so you can wear it without stress.
There are only scratches on the crown and back cover of the case, but there is no problem with the dial or movement.


Overthrow, Chronos developed by the Kameido Factory under the name of Marvel.
Since it is the first wristwatch, it is a watch that has been made without compromise in everything from the development of the movement to the case design.

The slightly faded gold blends well with the skin, and is a piece that brightens up the colors when wearing suits and jackets that tend to be dark in color.
