Watch Review

Dial & Case Design

This watch has a fantastic navy blue finish to it that I’m sure lots of people are going to be fond of. The dial has a dual digital/analogue display that’s very easy and clear to read. I think the use of the 3 mini digital displays if very interesting, not something I see done that often. The case itself is made of stainless steel and wrapped with this thick protective resin that gives it that brilliant shock resistance.

Type Of Crystal

Protecting the face of the watch is a mineral crystal glass. This type of glass is specially hardened to be extra resistant to scratches and knocks. The glass is also shatter resistant that’s great for a watch designed for shock resistance.

Watch Movement

The watch features an impressive radio controlled quartz movement, it automatically synchronizes with an atomic clock that makes it extremely accurate. The watch itself is solar powered using Casio’s tough Solar technology.

Watch Size

This model is a little smaller than your typical G-Shock watch, but don’t let that fool you, it’s still a fairly large watch. The casing diameter measures 46mm and it has a thickness of 15mm. One thing to keep in mind is that these bigger watches aren’t always suitable for people with smaller wrists.


The strap is a standard size for a men’s watch with a 22mm width. It’s made of the same comfortable resin rubber that’s used on the casing surround offering great durability. The strap fastens with a typical buckle clasp that’s easy to operate.

Extra features

G-Shock are known for their multifunction capabilities and this timepiece is no different. A key feature of this watch is the multi-band radio controlled timekeeping. Extra functions of this watch include a world time display, world time display, automatic calendar,  countdown timer, 5 alarms, super led light, stopwatch.

Water Resistance Rating

The water resistance level of this watch is 200m, this is what you find in many of the G-Shock watches and something I’m always impressed with. A rating of 200m / 20 Bar / 600ft makes this watch suitable for professional marine activity, serious surface water sports and skin diving.

Watch Disadvantages

My Final Thoughts On This G-Shock AWG-M100SB-2AER Review:

The G-Shock AWG-M100SB-2AER is a great choice for those who loves the G-Shock range of watches but fancied something a little smaller than normal. The radio controlled timekeeping makes this a very accurate watch, it also includes lots of extra useful features. Overall it’s a watch that offers great value for money and is perfect for people looking for a tough, durable timepiece who don’t want to shell out a fortune. Why not take a look at a high quality analogue digital watch list next.

After looking into the watch design, quality, features, and pricing this watch received an 8.5/10 from us at The Watch Blog.
