In 1924, the first watch under the name Seiko was produced. Seiko also has the honour of producing the first quartz watch in the world under the name Astron. Thus by this fact only, one can get a basic idea of the rank of Seiko watches in the world of wristwatches. When this watch was first introduced, its cost was more than that of a medium sized car. However, this watch was a breakthrough in technology and set a new standard, which is being followed to this day

Seiko brand watches were originally produced by two different Seiko Corp. subsidiaries. One was Daini Seikosha Co, Ltd (Kameido,Koto-ku, Tokyo) and the other was Suwa Seikosha Co (Suwa-shi, Nagano). Two different companies produced one brand in order to improve technology through severe competition and to hedge the risk. Splendid watches were produced at both companies because of this tough competitionand this system proved efficient at hedging the risk.. If either company experienced production problems the other company could compensate by increasing production. Eventually Daini Seikosha Co, Ltd. changed it its company name to Seiko Instruments Inc. and Suwa Seikosha Co.

In 1985 Seiko and orient watches set up a joint factory, which produces millions of watches each year. Seiko watches are known for their reliability and accuracy in time keeping, which is why their watches have been used for official time keeping in major sports events and the Olympic Games, which is also an honourable rank for the company.

The company produces different lines of watches of which, the most famous are Seiko 5, Grand Seiko, King Seiko and Credor. Collectors, due to their high esteem and unique features, treasure these watches as prized possessions. Seiko mechanical watches are especially considered as prized possession by collectors. When it comes to Seiko classic watches, the older a watch, the more precious it is.

Prior to 1960 most people believed Swiss watches were the highest quality and Japanese watches were inferior. Seiko believed they were capable of producing watches of the same quality as the Swiss. In fact, they had already made two high-quality examples, Crown and Chronos . The Grand Seiko and King Seiko is the result of their beliefs. Who made it? Daini Seikosha and Suwa began discussions under the suggestion of their parent company, Seiko. It was decided that Suwa would produce the first Grand Seiko (GS) and King Seiko (KS) by Daini. The birth of GS and KS was followed by the success of the Tokyo Olympics and Seiko's victory at the astronomical observatory Concours.
