Casio 200M WR Shock Resistant Watch (Model: GA-100CF-8CR)

Casio G-SHOCK GA 100-1A1 Military Series

This military G Shock is meant for those who want something truly blacked out. It is built for those who protect us with it’s rugged, waterproof and shock-resistant exterior, the hallmarks of a great G Shock.

You have, of course, water resistance to 200m, which you can take diving, swimming, and even in the mud. Casio have added a reliable backlight LED to help you see everything you need to in the dark. It also comes with a Chronograph, dual-Time-display, Light, Stopwatch, and World time, which is great for those who are deployed overseas or travel between timzones a lot.

The only downsides of this watch is that although it is a “black-out” style watch, it is super hard to read in the dark, and is still highly reflective because of the glass. However, if you just want that cool dark look, then this is the way to go.

Specifications

  • Black-out Watch
  • Quartz analog movement
  • Mineral crystal
  • Resin case and band
  • Bright backlight, stopwatch, countdown timer, 31 zone world time, 5 alarms, automatic calendar

If you want an affordable G-Shock watch at just the right price, then this watch that is way under $100 is going to impress you.

It will suit most wrists with its smaller case size (47mm) but still has that classic G-Shock look. There is an easy to reach illuminator on the bottom, that also comes with afterglow.

You also get all the standard G-Shock water-resistance (200m) and shock-resistance, as well as the digital watch functions. However, because of the price point, you won’t get a Triple Sensor or Tough Solar on this watch.

Casio G-Shock GD400-9CR

If the standard G Shock protection just doesn’t seem enough for you, then this model with a face protector on the front will give you a little more peace of mind. The style is also a little more modern with the NATO style strap that combines the G Shock durability as well.

Casio G-Shock GWM500A-1 Digital Wrist Watch, Black
For Smaller Wrists

Casio G-Shock GWM500A-1

If you are after a G Shock that is not as chunky as the classic look they usually have, then this model is the perfect alternative. It reminds me more of the Timex Ironman series, so if this look is something you like, you might want to check out what they have on offer as well. This model is also perfect for those wanting something a little smaller, as it’s only 46mm across.

It goes without saying that this watch comes with G Shock’s signature protection with 200m water resistance as well as shock resistance. But where this watch also stands out is that it is solar powered. A great way to stop worrying about battery changes every few years, right?

It also comes with the standard features such as: Backlight with Afterglow, World Time, 4 Daily alarms and 1 Snooze Alarm, Hourly time signal, Stopwatch, Countdown Timer, Full auto-calendar, and 12/24 hour formats.
