This analogue-digital combination watch delivers more comfortable fit and outstanding durability with a robust exterior incorporating a guarding structure built with metal components. The watches of the G-SHOCK Master of G line, developed for professionals working in the harshest environments, come equipped with even tougher functionality. And the MUDMASTER takes this even further with the ability to handle the roughest on-land environments, earning the appreciation and trust of rangers and rescue teams operating in extreme environments. The comfortably sized GWG-B1000 features a metal exterior crafted with high-precision forging techniques and a carbon fibre-reinforced resin case that offers high strength and outstanding durability. Radio-controlled and solar-powered, the watch is also equipped with a triple sensor that keeps you updated with direction, altitude, barometric pressure, and temperature readings. Double LED lights and sapphire crystal ensure high readability so you always see the time and other readings, no matter what the conditions are like. Input a specific location in the app and the Location Indicator function moves the indicator hand at the 3 o'clock position to point in that direction so you stay on track at all times even when visibility is obstructed by extreme conditions like sandstorms. The use of bio-based resins for the case, some bezel components, and the band make for a watch that demonstrates the MUDMASTER commitment to the environment.

Not stylish, not cheap. Very comfortable, very rugged. I don't much care for quartz watches but if you must have a quartz watch these G-Shock watches are fantastic. At work I must wear gloves a lot of the time and if I need to check the time I have to remove my gloves and check my phone. It drives me insane, so I need a watch. I bought this because I was watching a watch repair video and saw a watchmaker wearing one and thought finally a rugged watch that I might buy. In my line of work I hate wearing my mechanical watches so I don't wear a watch at all. This is not a perfect watch. The light illumination is terrible. I had a watch 25years ago that was 10x better in the illumination than this expensive watch - however - if it wasn't for the sub par illumination it ... MoreNot stylish, not cheap.

I had a watch 25years ago that was 10x better in the illumination than this expensive watch - however - if it wasn't for the sub par illumination it would be the perfect watch for me. The fact it is solar powered makes it even better. The large analogue dial is very easy to read at a glance. The lume is below average for a $1000+ watch too. You can buy a watch in the $2-$300 range that has far better lume than this so it is most definitely sub standard considering the price. It is OK just - but hardly anything to get excited about and is disappointing. Also, it does indeed have a sapphire crystal and at this price point you would expect it to, so that part of it is covered. The compass, altimeter are incredible. The temp sensor gives a false reading if you're wearing it though so to get the correct temp you might need to take it off. Despite the poor back lighting and below average quality lume for a mid priced watch, I'd go as far as saying it is still the best watch I have ever owned regardless of price. It is very durable and reliable. The band is exceptionally well designed and despite being large fits very nicely.

Fantastic design. Smaller, more egomaniac and more wearable than the old mud master 1000 which was quite large. The light is a lot better and the ability to check battery level using one button and then also use the iPhone app to ensure settings are correct is great. Altimeter was accurate when climbing Munro’s. Calibration is easy before each use pulling crown out and adjusting in alt mode. I have 6 G-SHOCKs including MRG and MTG and this is my favourite

I've worm a MudMaster watch since they were first introduced & the quality & reliability is something I expect from a decent watch. I decided to treat myself to the latest version of MudMaster & I'm so glad I did. Apart from looking great, the functions are all useful in daily life. The fact that this version is solar powered is a bonus - no more batteries!! If you want a reliable, quality built watch, then look no further...

The watch feels heavy and premium with good materials; the buttons are good; the crystal is sapphire. It has the same cool functions as a rangeman such as barometer, compass, sun rise and set times. It's easy to see the time with the big lumed-uo hands. The problems are all basically related to the digital screen. It's small and negative display and consequently hard to read. If you actually want to use ABC functions and even normal digital watch features like stopwatch and timer then get a rangeman.
First of all I want to say that First Class Watches are always my first choice, when it comes to buying watches. Their customer service is the best that I have ever known. They also get watches that have been ordered, processed very quickly, and the vast majority of the time, they will be delivered to your door the next day.I ordered the GWG-B1000-1AER which arrived the following day. It’s the third version of the ‘Mudmaster’ representing the premium line of MASTER OF G. The first one had a rugged design that looked bomb-proof, the second was made a little lighter and stronger, by using a stainless steel bezel and a carbon and resin mix to protect the watch, but it lost the rugged look of the original. This ‘Mudmaster’ has managed to combine the best things from ... MoreFirst of all I want to say that First Class Watches are always my first choice, when it comes to buying watches.

This ‘Mudmaster’ has managed to combine the best things from the previous two models. It’s a very nice looking watch that also has a tough, rugged look, that looks like it can handle anything. It’s also got a different look to the dial, because of the new useful features that have been added to the watch. If you want a watch that you can wear outdoors, that can get covered in mud, that you don’t have to worry about at all, this is the watch for you. I love everything about this watch.

Disclaimer: I'm a long time fan of G Shock watches and this latest one doesn't disappoint. My first Mudmaster to complement a Mudman digital watch also bought from D C Leake earlier this year.This Mudmaster is fantastic, built to usual G Shop standard and looks great on the wrist. In addition to the usual solar power and Multi Band 6 timekeeping the watch also supports Bluetooth to enable config changes to be made from an app rather than the pushing of multiple buttons like so e arcane sacred ritual.Purchase from DC Leake was excellent as ever. The watch arrived within 24hrs even though I didn't pay extra for next day delivery. If you haven't bought from D C Leake have no worries. They are available via chat or phone of you have queries and website is slick and ... MoreDisclaimer: I'm a long time fan of G Shock watches and this latest one doesn't disappoint.

Outstanding design and really useful features outdoors. As I’m very active in a field, this watch is perfect addition to my g-shock collection and upgrade to my really good Mudmaster GWG 2000. The build quality is excellent and matches my MR-G’s. The Red version looks really unique and timeless. All features work perfectly straight from the box, including multiband 6 auto time calibration during the night. Highly recommended!
Waited ages for this to come back into stock to purchase. It is a very nice watch with Bluetooth connectivity to make changes very easy for date, time, world time etc.I was however disappointed that the watch face is smaller than the previous model, and doesn't look as rugged.There are no dimensions in the specification either, whether this is on purpose or not, I don't know.The Casio site pictures makes them out to be the same size as previous model, but sadly not.Would have been 5 stars otherwise.
