What does radio sync solar mean?

Radio sync solar is the latest technology used by modern watch manufacturers. The watch has a Radio signal receiver built into it, which interacts with the particular radio channel. 

These radio channels send the information to the connected watches and update the time and date automatically every day. 

The watch precisely adjusts the time and calendar, giving you up-to-date time sync to all the solar chronograph powered watches in the world. 

It is supported by radio signals that travel at the speed of light. Any change in the time is reflected instantaneously on your watch.

Moreover, the users can control the manual signal receiver and optimize the time zone according to their needs. The manual operation will allow you to set the preferred time on your watch. 

The watch is designed to receive official standard radio signals from different countries. It supports the Radio signals received from the USA, Germany, China, Japan and UK. 

All these countries are connected through 2 separate transmitting stations. You can set your preferable transmitting station for receiving the radio signals in the world time function. 

What are the features of the Seiko Radio sync solar watch?

For Black Lovers

The radio wave movement in the watch allows the watch to sync the time all across the globe. It sets the time in all Seiko watches powered by the Radio sync solar watches with high precision. 

The watches are capable of receiving signals from the atomic clocks. It can cover wider geography by interacting with the radio signal, and the objective of the watch is to offer accurate time to the person wearing the Seiko watch. 

The system works autonomously without needing human interaction to set the time. When the condition allows, the watch synchronizes the time automatically three times a day. 

The watch offers you an option to set the time and date manually as well. Just with a button press, the watch starts gathering information from nearby radio signals and setting the accurate time. 

Seiko is known for delivering high-quality watches that are durable, accurate, and reliable. The operation of the watch excels when it is connected to solar power. You do not have to charge the battery or replace it. The watch is charged and run by solar power. 

The battery never needs replacement or change until the lifetime. If we talk about precision of the Seiko watch, the watch loses one second every 100,000 years. The internal calendar is set to run for the next 100 years without touching the reset button. 

The watch is designed to reduce the time it takes to adjust the time and date. It performs the common tasks autonomously, giving you an edge over the regular watches.

Shiny Look For Your Hand

The Seiko watch comes with auto-syncing of the current time and date using the Radio signals received from the two regional channels. The watch adjust the time accurately based on your region. 

However, if you want to manually set the time and date in your Seiko radio sync solar watch, there is a simple way to do it.

Like any other watch found in the market, the Seiko watch also comes with a button on the watch’s right side, the “Crown”. The crown is used to set the time of the main dial and sub-dial section. 

When you want to change the main dial, which is the time function, pull the crown outside gently. 

Remember that there will be two levels in the crown. The first level is used for the sub-dial system. The second level is for the primary dial system. 

Once the crown is set to the main dial, move the crown clockwise to set the preferred time. After that, push the crown to level one and start moving the crown again to set the sub-dial system.

To set the date in the watch manually, press the left side button. The left button starts the auto changing the date. Hold the button until you reach the desired date and tap the button again when the correct date is arrived, to stop the calendar. 

Once both time and date are set, press the crown to the normal position. Ensure that you screw the crown properly. If it is not fixed correctly, the water or any liquid can leak in to the watch, and your watch will no longer be water-resistant. 

Following the aforementioned, you can set the time and date in your Seiko watches manually. The Seiko watch adjusts the time automatically no matter where you are in the world. 

The only condition is that the watch should be in the range of the Radio signal. If the radio signals are not able to reach the watch, it will not perform well.
