Citizen Watch, the world leader in radio-controlled watches. Introducing their unique technology, history, and latest models.

A radio-controlled watch is a watch that can receive standard radio waves and automatically adjust the time. Citizen Watch is a watch manufacturer that has always been at the forefront of the world's radio-controlled watches. What makes Citizen's radio-controlled watches so great? We will introduce their features and history.

Features of Citizen's radio-controlled watches

Citizen Watch, renowned as one of Japan's leading manufacturers of practical watches, has developed a number of unique technologies. First, let's take a look at the features of Citizen's radio-controlled watches.

"Multi-station reception" supports overseas transmitting stations

Citizen Watch is the watch brand that created the world's first multi-station radio-controlled watch, which is a watch that can receive standard radio waves from multiple transmitters.

Citizen's radio-controlled watches are compatible with transmitters in Japan, China, the United States, and Germany. There are two transmitters in Japan, which cover almost all areas of the country.

"Perfex" technology that prevents misalignment

Perfex is a function that prevents the time from being misaligned due to magnetism or shock. It is a unique technology from Citizen Watch that combines three functions.

The JIS Class 1 magnetic resistance rating prevents misalignment due to magnetism, and the shock detection function prevents misalignment due to shock. In the unlikely event that the hands do become misaligned, the automatic hand correction function detects the misalignment and instantly corrects the time.

Citizen's radio-controlled watches receive standard radio waves from four areas around the world with high sensitivity, and by incorporating Perfex, the accuracy of their time display is further improved.

Unique photovoltaic system "Eco-Drive"

Eco-Drive is a proprietary technology of Citizen watches that eliminates the need for periodic battery changes. It runs on sunlight or even dim indoor light, and if fully charged, it will usually continue to run for over six months in the dark.

Although photovoltaic systems are a technology found in other watch manufacturers, Citizen Watch was the first in the world to develop a radio-controlled watch equipped with a photovoltaic system.

The journey of Citizen's radio-controlled watches

Citizen Watch is a Japanese watch manufacturer that has played a pioneering role in the field of radio-controlled watches. We follow their progress, exploring the many technologies they boast.

1993: The "multi-station radio-controlled clock" is born

Citizen Watch began developing radio-controlled watches in 1989. This was a challenge for Citizen Watch that started from scratch, and at the time there were a mountain of technical challenges to overcome.

After overcoming numerous challenges, they succeeded in developing the world's first multi-station radio-controlled watch in 1993. They adopted the bold idea of ​​placing the antenna in the center of the dial to prevent it from being affected by metal parts.

1996: Equipped with a photovoltaic power generation system

In 1996, Citizen Watch incorporated its proud Eco-Drive technology into a radio-controlled watch, becoming the first company in the world to achieve this feat by incorporating a photovoltaic system into a radio-controlled watch.

This eliminates the need to set the time and the hassle of periodic battery changes. The antenna is located on the left side of the case to improve reception performance and design.

2003 Development of a radio-controlled watch with a full metal case

In 2003, Citizen Watch developed the world's first radio-controlled watch with a full metal case, significantly improving reception sensitivity through improvements to power saving, antenna precision, and receiving circuitry, paving the way for a design that doesn't look like a radio-controlled watch.

The range of models is expanding

Since introducing the world's first full-metal radio-controlled watch, the development of radio-controlled watches has become one of Citizen Watch's main businesses.

As the pioneer of radio-controlled watches, Citizen Watch's challenges are never-ending, as movements are becoming more space-saving and antennas are becoming smaller.

The latest model of Citizen's radio-controlled watch

While radio-controlled watches originally had exposed antennas, Citizen has now refined their exteriors to resemble those of standard luxury models. Check out the latest Citizen watches and experience the magnificent development of radio-controlled watches.

"Citizen Exceed" Tanabata motif "Milky Way" limited edition pair model

This limited edition pair model from Exceed, known for its elegant and sophisticated design, depicts the romantic story of Orihime and Hikoboshi, who are only allowed to meet once a year on July 7th.

The dial, which depicts the night sky, features stars representing Vega and Altair at the 7 o'clock and 7 minute positions, respectively, and at 7:7 the hour and minute hands connect the two stars like a bridge over the Milky Way.

Eco-Drive radio-controlled watch equipped with Cal. H147 to be released in March 2024

The radio-controlled watch from Citizen, announced in March 2024, is a slim model among multi-station light-powered radio-controlled watches equipped with the new Cal. H147 movement. The total case thickness is approximately 7.0 mm.

The dial design is simple, with only a time zone display and no city indication. The diamond-shaped hands give the watch a sharper impression in combination with the case design.

The case and bracelet are made from Citizen's proprietary "Super Titanium," a material that is scratch-resistant and gentle on the skin.

If you want higher accuracy, choose a Citizen radio-controlled watch.

Citizen Watch is a watch manufacturer that has been a global leader in radio-controlled watches, not only developing a variety of innovative technologies but also contributing to improving the design of radio-controlled watches.

Learning about the history and appeal of Citizen's radio-controlled watches will help you develop an even deeper attachment to your favorite watch.
