G-Shock pseudo-nerd here. I used to be seriously into them. I actually had a G-Shock when they first came out. I remember the screw-back case. When the battery went dead, I took my bike to a nearby watch service shop to get a new battery and they quoted me a crazy expensive price. “We have to pressure test it.” It was more than what I paid for the watch. Well, they were trying to rip me off and I didn’t know it. Watch went into the drawer and forgotten. Some years later when I decided to give it another go, rescuing it from the drawer turned up a watch with a bezel that had disintegrated (early resin formulation flaw that would haunt some CASIO models later on too). I left it, but then during my time at college my mother did a “room clearing,” tossing out old junk, and she figured it was broken. It was tossed. If I still had it, it would be worth more than the original purchase price!
Resin bezel degradation ruined some models completely, like the DW-1100 and DW-1200. Very few escaped demise. And it’s insidious. You could buy a pristine looking mint example, bezel seems fine, then one day you touch it and it breaks in half. Actually, some models look pretty good without the original resin bezel.
When I’d gotten into using a proxy service to buy off of Yahoo Japan, I found so many CASIO watches up for auction. It was overwhelming. Back then (around 2008~2010), the CASIO watch forum on Watch U Seek was a buzz. Everyone was Frogman crazy. I didn’t like the asymmetric shape. So for me, the G-2000 was king, often called the “poor man’s Frogman.” The problem with the Frogman is that it had no depth sensor. Anyway, the G-2000 was released in so many colorways. I ended up collecting almost every variant, but then found the GL-110, which I found more interesting. That’s a great screw-back design.
I almost bought a GW-5000, which is a terrific watch, but there were always other vintage models catching my eye. I like quirky ones. The G-3000 is one of those. The ML version is a favorite. One great thing about it is a loud alarm. My big beef with most G-Shock watches is the anemic alarm tones. The GW-M5600 / 5610 is the absolute worst. So faint, as to be useless anywhere but a quiet room.
One of my favorites is the original MRG-1. I was able to get a combi bracelet to fit it and it’s such a nice look. My other favorite is the GD-350. It’s a vibration alarm watch with quick access CDT. I set it for 4 minutes and it’s terrific for grilling. A 4 minute interval is great for timing when to check on food grilling.
I never picked up a modern all metal MR-G, but did get an MRG-220. It was the last of this particular all metal MR-G design. Very artful aesthetics. The solar recharged, Bluetooth and Radio sync sapphire crystal MRG models costing thousands was just way out of my budget.
My favorite of the non-GShock models is the all titanium TW-7000. It came out in the 1980’s and was pretty expensive at the time. Later I picked up a couple before the collector fever resurgence. So slim and easy to wear. Very limited functions. Battery changing is a real PITA. It doesn’t have a conventional battery holder. Very tricky to do without using 2 sets of plastic tweezers.
So yeah… I guess you could say I’m a vintage G-Shock / CASIO nerd.
