History of Seiko

If you have not heard of Seiko, then I’m afraid you need to get out from under that rock you’ve been living. One of the most well-respected watchmakers around the world, Seiko is a Japanese company that is synonymous with watchmaking innovation. Founded in 1881, Seiko was initially a jewelry shop in Tokyo, Japan. It was not until 1924 when Seiko officially entered the wristwatch market.
Seiko made their initial “first” with the Astron which introduced the world to the quartz movement watch in 1969. This revolutionary timepiece kick-started the quartz watch revolution of the 70s. Most watch brands followed suit shortly after with their quartz watches to compete with Seiko.
Less than a decade later, Seiko unveiled another first in the industry, this time in the form of a solar-powered watch in 1977. This technology helped further cement Seiko as the premier trailblazer in the watchmaker industry.
At the very tail end of the 20th century, Seiko once again introduced a new element to watchmaking with its Spring Drive movement technology. This technology is designed to withstand space travel while still providing excellent accuracy when telling time.
2012 saw the return of Seiko’s original flagship series, the Astron. This time around called the Seiko Astron GPS Solar watch. The current Astron watch series contains all the features that helped Seiko climb to the top of the mountain, all in one sleek and stylish timepiece. Put, Seiko is always delivering the goods when it comes to watches that few can match up.

History of Casio

The Japanese company, Casio, is not only known for their robust digital watches, but also with other electronic devices. Originally a manufacturer of microscope parts and accessories that was founded in 1946, they managed to expand their repertoire by 1954 with their electric calculators.
Casio made strides in the electronic device industry is one of the most trusted names in the business. Casio entered the wristwatch market with their most popular watch series, the G-Shock, in 1983. The G-Shock is marketed as one of the most robust digital watches around while maintaining a budget-friendly price tag.
Their G-Shock line quickly rose in popularity due to its sporty appearance and incredible construction. In an era where traditional and sleek watches were the norm, the G-Shock managed to carve its niche with its rugged and tank-like design.
Due to G-Shock’s impeccable durability, it became a staple with outdoor activities and sporting events. The Baby-G series, a sleeker and more lightweight variation of the G-Shock, was introduced in 1994. The Baby-G series was a perfect option for those who feel that the main G-Shock series are too bulky for their taste.
Thanks to the G-Shock watch series, as well as the company’s knowledge in developing electronics, Casio managed to rise the ranks of digital watchmakers. You can point to Casio as the premier developer of reliable digital watches in the market today.
G-Shock’s popularity has transcended the market and has become a part of pop culture history. Many of the popular action films in the 90s, like the Keanu Reeves high-octane film, Speed, showed the hero wearing a G-Shock watch throughout the movie.
Casio was also the first to break into the smartwatch market back in 1991. Yes, Casio was already tinkering with the idea of smartwatches back then with their Casio VDB-1000. It was so ahead of its time with its touchscreen functionality and built-in organizer, notepad, and phonebook. If you are looking for a reliable digital watch, Casio should always be included at the top of your shortlist.
