G-Shock Mudman GW9500-1

Earlier this summer, John wrote about the new G-Shock Mudman lineup (seen here), taking that rugged and robust design into a slightly more modern aesthetic. I’ve been spending time with one for the last few weeks, and now we’re ready to give our take on the G-Shock Mudman GW9500-1.

What is it?

In short, it’s a modernization update to the Mudman. It makes for a more compact watch (though, if you want a very slim G-Shock, we might point you at this one), but one that is immediately recognizable as a G-Shock. Of course, it’s not just looks for looks sake. No, the construction of the G-Shock Mudman GW9500-1 is all about making a watch that can stand up to whatever is thrown at it, including mud- and water-resistance. Hence, it being called the Mudman.

What all can it do?

It might be easier to think about it in terms of what the watch can’t do. In short, it won’t talk to your phone, and it won’t collect your steps or heart rate. Past that, it can do just about whatever you’d need a watch to do. A lot of that is enabled by the triple-sensor technology, which packs a barometer, compass, and thermometer into the watch. Add in the fact that it charges via solar, and you’ve got quite the outdoors-oriented watch. On top of all of that, you’ve got a comprehensive suite of digital watch functions, including alarms, chronograph functions, world time, and the like. Take a look down below, and you’ll see all the great things this watch can do for you.

What’s it like wearing it?

Even though the G-Shock Mudman GW9500-1 is a bit slimmer than the Mudman models that came before, there’s no denying that this is a large watch. At 52.7mm from side-to-side, you will notice this watch on your wrist. Thankfully, with the bio-based resin used for the case and strap, the overall weight is just 81g, which means it won’t weigh you down. And as you can see from the photos, it wears very well on the wrist for it’s size. This is due in part to how they’ve designed the lug drop-off from the case, allowing the watch to hug in closely to your wrist.

Past that, all of the pushers are clearly labelled, and it does not take long to get a hang of where all the functions are, making the use of the watch pretty straight-forward. We wouldn’t mind being able to have a second time zone displayed (rather than the day/date) on the main time display, but that’s a relatively minor quibble in the grand scheme of things.

Would we recommend it?

In our book, a fully digital watch that also is solar-powered and radio-signal syncing is always a good option to have in the watchbox. Add in the basic toughness of the G-Shock Mudman GW9500-1, and this is a great watch for anyone who spends a lot of time outdoors. In the past, we would normally point someone in the direction of the Protrek lineup. Now, with this latest Mudman out there, the decision gets a bit trickier. With the triple sensor appearing here, that blurs the line between the two sub-brands a bit. However, if you’re a bit rougher on your gear – or you just want the more rugged appearance – then the $380 G-Shock Mudman GW9500-1 is a solid option that will last you for years and years. casio.com
