The Casio GW-9500 Mudman isn’t my first G-Shock by a long-shot. I thought it would make a bit of sense explaining what it’s like to live with and why I wear it at a time when the world is becoming more connected and documented.
My relationship with the Casio G-Shock started with my time scuba diving. At school my friend Neil had a Casio DW-100, which was a pre-G-Shock digital dive watch, only available in the Japan and the US at the time.
I was introduced to diving when working in my second job out of school by a colleague. I started using an old DW-5500 attached by an Animal velcro strap to my buoyancy compensator of my dive kit, that was gifted to me by a friend. It served as a back-up timer to my dive watch. I couldn’t afford a dive computer. At the time I had a friend who worked in a dive shop and my lessons were done by former military divers. I probably couldn’t afford similar equipment now if I decided to return to driving.
I also wouldn’t be doing the kind of dives we did back then thanks to the governing bodies de-risking the sport to the point of boredom, that’s a subject for another post.
Why do I wear a GW-9500 now?
It makes sense to tell a little bit around why I wear G-Shocks. I want an accurate watch (who doesn’t?). I want a dependable watch (again, probably a hygiene factor for most people). G-Shock offers robustness that 30 years ago would have come from fine Swiss or Japanese engineering – but at a much lower price point. Although the price point for G-Shocks has been steadily increasing.
The GW-9500, alongside other G-Shocks is what watch people would call a ‘beater’. It will take whatever life throws at it, from colliding into door handles, being dropped, to its water resistance – you don’t have to worry about it.
G-Shocks are the grey man of watches, despite some models being colourful – they are ubiquitous on any street from London to Manilla. They blend in with the crowd and are less likely to draw attention. This makes them the ideal ‘London watch‘.
The Apple Watch is closing in on this status in London now, but requires regular charging and is also more fragile than your average G-Shock.
I work in a creative role, my usual work outfit consists of:
- T-shirts
- Flannel shirts, sweatshirts or fleece quarter-zips
- Jeans or climbing pants
- Suede hiking boots or trainers
All of which make the G-Shock an ideal accessory for my form-follows-function wardrobe.
Industrial design of the GW-9500
The design of the GW-9500 is based on form following function. The buttons are designed so that they can be pushed with gloves, but still protected from accidental use. The ‘armouring’ helps protect the watch screen.
Casio worked out a lot of these lessons with the early Casio G-Shock Mudman and Rangeman watches. These models in turn borrowed the learnings of even earlier G-Shock models. G-Central did a good job at teasing out all the G-Shock family tree that led up to the GW-9500 – the link is at the bottom of the article.
The feel of the industrial design evokes the product design in Japanese anime like Ghost In The Shell or Evangelion – where things are over-designed. That has a certain appeal for me.
Materials
One of the biggest steps forward with the GW-9500 is the materials that the watch is made from. The movement and glass is held in a carbon fibre composite case. In my other G-Shock watches, this core case is made of plastic, stainless steel or titanium. This is one reason why the GW-9500 is very noticeably lighter than my other models. It’s also noticeably thinner, yet still offers the same protection.
Casio also has one eye on sustainability, with the watch strap being made of plastic material made from biomass rather than oil based plastic. The plastic is tough but not as supple as the polyurethane straps on cheaper G-Shocks. This bio-plastic strap isn’t as comfortable to wear and doesn’t break in over time. Ideally if I had the option, I would switch the strap out for adaptors and a NATO strap instead, even though it would ruin the aesthetic. After four decades, Casio could still learn a lot from Seiko’s polyurethane dive watch straps.
Connectivity
I have mechanical watches, an Apple Watch Ultra and my range of G-Shocks including the GW-9500 sit somewhere in between these two technological extremes.
The GW-9500 syncs its time via a series of atomic clocks that broadcast around the world. It is aware of its surroundings thanks to its digital compass, altimeter, barometer and temperature. All of this isn’t new technology,
A compass is surprisingly handy even in today’s age. The enemy of satellite navigation is tall buildings. They increase the amount of time that GPS takes to lock on and you end up with less precise positioning. A compass doesn’t have that problem allowing you to orient yourself.
Casio seems to have raided the parts bin of its ProTek series of watches. It doesn’t have Bluetooth, wi-fi or connect to a phone app – which means that obsolescence is less of a concern.
Power comes from on face solar panels that keep the watch battery topped up, rather than relying on a cradle like smartwatches.
Having a watch that just tells the time and has a timer or two for cooking allows me to disconnect from the always-on connected world of the smartwatch and smartphone.
Display
The display on the GW-9500 had a large screen that unlike its G-Shock peers doesn’t make an efficient use of the real estate. That approach has benefits, the sparce screen design and large numerals provide a very glanceable display.
It is well illuminated by a while LED that covers the whole of the display. The light is carefully balanced between bright enough to be clearly legible, and dull enough to not ruin your night vision.
Software
One of the benefits of getting a G-Shock over the years is that you feel right at home, for the most part, new G-Shock watches like the GW-9500 operated like older G-Shock models. The exception to this is when Casio tries to become a connected smartwatch as that part of the market is still in flux.
However the legacy software model requires a degree of patience in comparison to modern phone apps. The GW-9500 like all legacy G-Shocks uses what’s known as a modal approach. You want to set something you go into the set mode and then cycle through to the feature that you want to change. If you don’t get it write, then you have to cycle through the different functions and start again.
I grew up setting my parents video cassette recorder and answering machine so the experience isn’t that alien to me. The Hemingway Editor app also takes this approach with two modes: ‘write’ and ‘edit’ which works well with my text creation process.
As a watch experience, it works perfectly well, and once you have done it a few times you can use 80 percent of any legacy G-Shock watch without consulting the instructions – which still come in a satisfyingly thick paper book about the size of a box of matches.
Are there things that I would like improved? Yes, absolutely. A bugbear of mine, working with other people around the world is the different time zone function. A feature it shares with ChatGPT at the time of writing is that the GW-9500 doesn’t allow for countries which have daylight savings times changing in time difference during spring and summer. So I have ended up calling Asian colleagues an hour early by accident.
Is the GW-9500 a keeper?
The Casio Mudman GW-9500 has its faults, such as comfort, when worn for a prolonged time and the time-zone issue. But those are minor compared to its benefits.
