G-Shock is one of the flagship products of the Japanese electronics manufacturing company, Casio. Best known for its extreme durability, G-Shock first made its mark in the market back in 1983. The G-Shock watch line is aimed at the thrill-seeking crowd, sports, and outdoor enthusiasts. This is also reflected in the watch line’s overall sporty and colorful aesthetics. G-Shock watches are also developed using the Triple 10 concept. The Triple 10 design incorporates the three ‘10s’ – basically, a 10-meter freefall impact resistance, 10-bar water resistance rating, and a battery life of up to 10 years.

Even the most affordable G-Shock watches also come with a stopwatch, countdown timer, and alarms – further pushing forth their outdoor and sports watch reputation. Throughout the years, G-Shock has continued to evolve and include more signature features. Two of the main elements that have recently become a staple of this watch line are the atomic clock timekeeping synchronization and Tough Solar technology.

In this article, we will be shining the spotlight specifically on the atomic solar-powered G-Shock watch. But before we do so, what exactly are these two timepiece technologies, and are they worth the price of admission?

Atomic Timekeeping

A watch with atomic timekeeping is considered as one of the most accurate timepiece movement in the industry. The high accuracy is achieved by utilizing radio signals received by the watch movement which it then uses to automatically adjust in real-time. The atomic timekeeping is so reliable that this is used by NASA as their countdown timer during liftoffs.

When it comes to reliability, it is said that an atomic timekeeping watch loses one second every 15 billion years! Obviously, nobody would be able to prove that claim, but based on actual data that we have right now, this is highly probable. When it comes to precision, you can never go wrong with an atomic watch

Solar-Powered Technology

G-Shock is also known for utilizing Casio’s Tough Solar technology, further boosting its capabilities in regards to outdoor use. Solar-powered watches, as the name implies, uses the sun to charge their batteries. Modern solar-powered devices can actually utilize both natural and artificial light which is absorbed by a solar panel and converted into electrical energy for the mechanism. Solar-powered devices can also store energy which allows them to keep on ticking during the night.

The advantage of having a solar-powered watch is manifold. This type of technology is eco-friendly, low-maintenance, and highly reliable. You can expect Casio to continuously push the envelope with this technology during the next couple of years and beyond. Here is a full introduction to Casio’s Tough Solar technology to further give you a clear view of its capabilities.
