If you're planning a diving trip to the ocean, a diver's watch is essential. Casio, the manufacturer of G-SHOCK, also has a lineup of must-have models for divers. We'll introduce the latest and classic models for 2023, focusing on the Frogman, known as the G-SHOCK diver's collection.
Casio's diver's watch exudes strength and functionality
When asked about Casio's signature product, many people would answer "G-SHOCK." Launched in 1983, G-SHOCK has been loved by many fans for many years for its core performance of "toughness."
Before introducing popular diver's watch models, let's explore the history and evolution of the FROGMAN, a G-SHOCK watch that is specialized for use underwater.
The origins and history of the flagship model "Frogman"
Casio's first diver's model, the Frogman, was born in 1993. The first model, the Frogman DW-6300, was a diver's watch that complied with ISO standards and was water resistant to 200m.
Diving watches, also known as "diving watches," are defined by ISO and JIS standards. A diving watch is a watch that can dive to a depth of at least 100 meters, has a timekeeping function, and meets a certain level of pressure resistance.
The Frogman has been constantly improved since its initial model, and a model equipped with a depth gauge was released in 2016. It also has various measurement functions for professional divers, making it a flagship model that has evolved to be useful for carrying out missions at sea.
Waterproofing features of Casio products that you should choose based on your needs
When choosing a diver's watch, it's important to keep in mind the differences in water resistance. The required water resistance and pressure resistance differ depending on the intended use. Let's take a look at the differences between 200m diving water resistance and atmospheric water resistance, which are the basics when selecting a diver's watch, and the appropriate use cases for each.
For scuba diving, it is waterproof to 200m.
A diver's watch is designed for scuba diving, which is its primary purpose, and is water resistant to at least 200 meters. If you are serious about diving, you should consider a model with this capability.
The Casio Frogman is ISO-certified and 200m water resistant, making it a prime choice for anyone considering a diving watch.
There are many diver's watches available that are designed for saturation diving or have a water resistance level higher than 200m. For general recreational scuba diving, the 200m water resistance of the Frogman is sufficient, but depending on the diving depth and purpose, you may need to consider a watch with a higher water resistance level.
For skin diving, "10-20 atmospheres water resistance"
For swimming in the ocean or skin diving without oxygen tanks, a water resistance of around 10 to 20 atmospheres is sufficient. 10 and 20 atmospheres are classified as "enhanced water resistance for everyday use." While not suitable for serious diving, they can be used for leisure activities such as swimming, windsurfing, and skin diving.
The majority of Casio's G-SHOCK series are water resistant to 20 atmospheres, so depending on the situation you want to use it in, you may want to consider watches other than the Frogman.
However, when doing marine sports or skin diving, strong water pressure is applied depending on the movement. If you plan on doing intense activities, it is safer to choose a watch with high pressure resistance for 200m diving.
