The GWG-100 Mudmaster looks to be a good option for those who want the tough look and ruggedness of the GWG-1000 but in a smaller and more affordable version, and prefer a solar and radio-powered model over the GG-1000 Mudmaster with Twin Sensor. A distinguishing feature of the GWG-100 is the full auto double LED light with both the Neon Illuminator for the hands and index and the Super Illuminator for the LCD displays, versus the standard double LED light of the GWG-1000 and the sole Super Illuminator of the GG-1000. The Neon Illuminator is essentially a LED “black light” that illuminates the analog hands and markings very clearly in the dark. Features include shock resistance, 200-meter water resistance, mud and dust resistance, Neo Brite luminous hands and markers, Tough Solar, Multi-Band 6, world time (48 cities + UTC), 1/100 second stopwatch (60 minutes total with split), countdown timer (100 minutes), 5 alarms, battery level indicator, and full auto double LED light with Neon Illuminator and Super Illuminator.

Yes the Watch is brilliant , but i would like to shower the Praise on the Watch Shop .They were simply stunning , every move went perfect . The ordering , the speed of Delivery andthe Quality of the Packaging . First time to use them , and i was blown away with the Quality of the Service . Now for Example in the Amazon Reviews , they give you 5 different categories to tick and each box has 5 sub boxes to score in . Well if that was on this review , then every boxwould rate 5 for top marks . A damn good Firm . Mr Ken Picton

Really great looking watch that functions with classic Casio quality and precision. Love the chunky size, it is a big watch but wears easily and comfortably. Nice and light but definitely a lot of wrist presence. The blue toned light function is a thing of beauty and the lume is excellent and fit for purpose. This black with green strap combo is the nicest, in my opinion but the other versions may be more to others' taste (black and grey with red accents, and I think a black with black version.) Bought the watch as a super tough daily wear for working outside, at the gym after work and camping, outdoorsy stuff at weekends. It is perfect for this and takes everything in its stride. Too many functions to mention; the lack of second hand bothers some people but it is ... MoreReally great looking watch that functions with classic Casio quality and precision.

Think the watch is worth the money; and the function to set the time using atomic radio is super cool, the cheaper GSG version doesn't have this function. Solar powered battery is also very cool. All in all, delighted with it and would totally recommend.

This watch is great. It is a big watch so if you have small wrists take that into consideration.It is a little stiff at first but after a week of wearing the watch it breaks in nicely. Atomic timekeeping is the way to go, if you want accurate time. Solar power also is a must for me when spending over $250 on a g shock watch since you won't need to replace a battery. This is not a twin sensor so keep that in mind but I believe this watch looks the best out of all the GWG models and is the reason i bought this watch. I have had many compliments on this watch. The only complaint i have is i wish the back light was a bit brighter, other than that you can not go wrong with this purchase.
Replacement for a well battered and well used 14 year old G-Shock. Wanted a watch that could cope with an often dark work environment without the need to press buttons to tell the time as well as one that could cope with the dust. Did have a concern about the bracelet.Pros: a lot lighter than 'old' G-Shock. Bracelet very sturdy (double pronged - not single pronged as most buckles are) and will well outlast a metal one in appearance.Cons: has gone down in price since I bought it. C'est la vie,On my wrist within 20 hours of ordering. Informed at every stage of order process. Excellent (5/5) customer service. Down to taste whether a watch is 5/5 as always something you would wish to alter over time (I'll just have to buy another later if my taste changes) but has ...

If this watch gives me the same service as 'old' G-Shock it will prove a bargain.
I was afraid it's gonna look hilarious on my skinny wrist, but it's not as big as I thought it will be.Excellent watch with all features I wanted.Build to last with, solar charging don't need to worry about battery level at all.Tough watch, ready for everyday tasks.Feels good on wrist as well, just need to get used to the weight, but after day or two you barely realise that you wearing it.Manual that is coming with watch does not tell you everything, so be ready to watch some online tutorials.Overall it's an excellent watch, and I am very happy with my order.BTW it arrived early without any tracking, and I received the email about delivery 2 weeks later.
Its basically the mud Master without the triple sensor stuff and great illumination. If you need to see what time it is at night. Its not atomic but it is solar and it loses about 15 seconds a year if you said it with any atomic watch.
I have owned the GWG-100 for a few years. It has never kept accurate time. The time zones function doesn’t work properly which is a shame as I travel a lot.It is tough and the light works well but it is always at least 5 minutes fast or a few hours out if in different time zones.Spent more money and get something that works.
Having came across the G-Shock GWG-100 online. I emailed first class watches when I found it cheaper elsewhere. The price was matched and I ordered it on the following Saturday. The watch arrived on Tuesday via DPD and is better than I expected. It fits nicely, the timekeeping is accurate to more than a second and is now fully charged with it being solar. An absolute beast of a watch and for day to day timekeeping is incredible. This is my first purchase of a G-Shock and my first time ordering from first class watches. I shall be checking back in future when more purchases are to be made if they are in stock at the right price.
Having had this watch on my wrist for a couple of months now I can say that I am mildly disappointed with its general operation.Firstly my negative observations:-Despite placing it in direct sunshine/daylight for an hour every morning from day one, which should keep its solar battery completely topped up, it very quickly loses its charge during the day and, for the most part, indicates that it is only moderately charged up. I find this concerning especially since the manufacturers claim it will run in total darkness for several months.Secondly, one of the main reasons I bought this watch was for its ability to display time/day/date/month with atomic accuracy. Although this is true, I have found that it is very difficult to glance at and immediately be able to ...

I find this concerning especially since the manufacturers claim it will run in total darkness for several months.Secondly, one of the main reasons I bought this watch was for its ability to display time/day/date/month with atomic accuracy. Although this is true, I have found that it is very difficult to glance at and immediately be able to read the dials because they are deeply recessed and the numbers/letters are very dimly highlighted. To obtain the details required, the watch has to be twisted and held at certain angles for the natural light to shine on it which is very irritating.Thirdly, at night, when the brief highlight facility operates, its display is totally confusing because it also highlights bars at the quarter hours. These bars tend to get confused with the hands of the watch. When the light goes out after a couple of seconds, invariably, I am still no wiser as to the time. Again, very irritating.My positive comments are that the watch itself is very robust as claimed by the manufacturers and, from my point of view, extremely accurate being regulated by the atomic clock.I can only say that, if there could be an improvement on my negative comments, the watch would certainly be a superb timepiece.
