An ultra-rugged quartz watch from Casio's G-Shock series of shockproof and waterproof models. They are one of the most balanced products in the series, designed for use in extreme conditions of sudden acceleration and high humidity. They will become an excellent companion for a user involved in sports, or just leading an active lifestyle. Perfect for water tourism and water sports.

They are distinguished by their signature aggressive design and impressive dimensions of the impact-resistant polymer case. The manufacturer claims resistance to falls onto a hard surface from a height of 10 m. An elastic rubber strap with a reliable classic latch is highly durable and is guaranteed to keep the Casio GA-100-1A2 watch on your wrist in any circumstances. The hybrid pointer/digital dial, protected by mineral glass, is equipped with a convenient automatic LED backlight with afterglow. The functions of an alarm clock (5 positions), a calendar, a timer and a stopwatch with a resolution of 0.001 s are implemented. With a Water Resistant rating of 200m, this model can be used for scuba diving and deep diving without scuba gear. Thanks to the high capacity of standard SR927W batteries, the watch has a two-year power reserve.

Great watch, flaws fixed in the GA-700 version
16 August 2017 
As an experienced user of many G-Shock series, I recommend: in 2016, a model based on the same GA-700 was released, and this problem has already been resolved. The case is identical, a big "+" is that the backlight button has been moved to the front part of the case as a separate functional element (much more convenient). The new design of the buttons and their protective rims facilitates a pleasant and easy press! The backlight also consists of one diode, BUT with the help of a luminous coating on the hour markers, full illumination of the entire dial is ensured. The price is the same!!!
These are very durable and reliable watches. I've been wearing G-Shock for 10 years and have 40 different pieces! Neither American Timex nor Finnish Suunto, considered the best sports watches, can compare to Casio G-Shock, Protrek, or Pathfinder in my experience. There are drawbacks everywhere, the key is to choose your watches wisely and patiently. It's a great model, I recommend it to everyone!
The hour markers could, of course, be coated with luminescent material, which would improve their visibility.

Totally worth the money, love it
31 March 2014 
The watch is not cheap, but very good quality. So far very pleased. We'll see how things will go with them in the future. So far, the impression is only the best.
Before purchasing, I read a lot of reviews - there were both positive and negative among them. For example, I often came across the opinion that these watches were simply not worth that kind of money. But the decisive factor was the ability to hold them in your hands and try them on (before that I only chose them via the Internet). The watch immediately captivated me - it was massive, matte black, and solid. In a word, I immediately decided that they suited me. I haven't been using them for very long. I handle them with care since they are new. Therefore, I cannot yet say that they survived both fire and water. But the impression is still the best. It took some time to customize them, but it was necessary to do it. They look great on the hand. So far, my opinion is that they still look like money that was not invested in them.
So far, I haven't found any drawbacks.
