In fact, the Seiko Astron is worn by celebrities of all ages, making it a watch that suits anyone.
However, since there are a wide variety of models, you should choose the one that best suits you. The functions also differ depending on the model, so be sure to check before purchasing.
Why Seiko Astron is loved
Highly acclaimed for its functionality and design, Seiko Astron is a popular brand among all age groups. Let's take a look at why it's so popular with so many watch enthusiasts.
GPS solar function
Seiko Astron, launched in 2012, is the world's first GPS solar watch. The "GPS solar function" employed by Seiko Astron uses satellite-based time correction and power generation using sunlight and other light sources. Using radio waves emitted by four GPS satellites, the watch displays the accurate time for any location in the world.
In recent years, the Astron has also released a "solar radio wave model" that receives radio waves from base stations to adjust the time. This model also runs on solar charging.
Additionally, the higher-end Cal.5x movement is equipped with a "high-speed time zone adjustment function" that allows the position and time information to be corrected with a single push when the time zone changes. This Cal.5x also features a "dual time display function" that allows easy switching between home and local time, as well as a "time transfer function," making it a particularly useful watch for business situations.
The "Super Smart Sensor," which automatically receives the time up to twice a day, is only available on the Astron. It also uses a solar charging system, so there's basically no need to replace the battery.
Mechanical and elegant look
Seiko Astron is not only focused on functionality, but also on design. Models with dials that contain a lot of information have an ingenious layout that prevents them from appearing cluttered.
The watch attracts men's interest by emphasizing its mechanical aspects, such as the flange around the index that creates a three-dimensional effect and the in-dial that improves visibility.
Another key point is its elegance. The careful processing and finishing of the case, crystal, and indexes gives it a beautiful and luxurious feel.
Wide variety
One of the reasons why Seiko Astron is so popular is its diverse lineup, which makes it easy to choose a model that suits you.
From sporty to luxurious, you can find models suitable for a variety of ages and fashion scenes.
Currently, Seiko Astron is available in five series: Nexter, Astron Origin GPS Solar 5X, Astron Origin GPS Solar 3X, GPS Solar 5X Regular, and Astron Origin Solar Radio-Controlled. Understanding the features of each series will make choosing a watch more enjoyable.
