Mine is the f-91w with an olive green nylon strap which i’ve been wearing since 2019.
A black G shock that’s been pretty much bulletproof for 20 years, then a white G shock where the physical hands will not match up with the digital time no matter how many times I reset it.
The one that makes TSA sweat

I’ve finally given up on Casio. My new g-shock is made of a lower temp plastic that is easily damaged from cooking. The glass isn’t nearly as durable as previous models. Plus the Bluetooth sync requires a terrible app and EULA. I’ve literally worn g-shocks for decades.
Ga2100
Pro-Trek 3500 in titanium. It has multiple sensors, radio-based time correction, a great display, a separate button for the backlight, and solar power. It you want a watch that blends in with the business-ware this is not it, but I like the way it looks.
I love my stealth GA-B2100 casiooak, it’s quite slight and great for casual wear, love the solar power on it.
I also have a Ga-2100-1a4er for work which is the same watch but without the solar and Bluetooth.
I have a Mudmaster GG-B100-1A as well which is basically bulletproof which has even had water inside it because I botched the seal replacing the battery, I dismantled it and dried it out works fine. The mudmaster is quite big and it was rubbing at my arm in the summer heat so I haven’t been wearing at work but will again now it’s getting cooler.
The mudmaster is stacked with features but I would recommend any Casio u purchase has solar. No more battery changes. Awesome
GW-5610 I bought secondhand for ~$80 and added an aftermarket stainless steel bezel. Uses multiband6 and solar. It’s been a fantastic bulletproof watch for the past ~4 years of near daily wear (I like watches so I wear something else if I’m in a particular mood).
That one I got back in the 80s as a kid where I could change the channels and turn off TVs everywhere I went. Man that was super fun.
I have a DW5600CU-7 that I wear most of the time. I have others but sadly they’re negative displays which make them a bitch for readability.
F-91W - Had mine for 20 years before I took it off and accidentally ran it over.
I rock my DBC610 almost daily.
If you want to spiff up your F-91W, get the sensorwatch.net module for it. The trouble I’ve had with those plastic watches though is that the spring pins that hold the strap break loose, and the strap falls off. If that hasn’t happened with yours, you’re doing good.
Not the F-91W. Who puts the light and the lap as the same button so checking the timer in the dark also stops it???

Can get one for $5 and it is a full calculator.
