I was shopping a cheap digital I could forget on my wrist against a rugged GPS watch I would actually charge. Two live Amazon listings stayed open: the Casio G-Shock DW-5600UE-1V square, and the Garmin Instinct 2 Solar in Graphite. I checked both in early September. This is that cart, not a phone-watch five-pack.
Casio G-Shock DW-5600UE-1V
When I checked in early September, the page did not give me a clean one-click new buy box. It showed See All Buying Options. An on-page figure of $53.56 sat there. I am not treating that as the price that lands in checkout. New, third-party, and used can sit in the same mess. Confirm the live offer before you tap buy.
Stars: 4.7 out of 5 from 23,077 ratings. That pile is huge. Stars are still other people’s taste.
It is a quartz digital. Battery. Resin strap with a buckle. Shock-resistant sports language from Casio. Alarm. Auto calendar. Flash alert. Hourly time signal. Stopwatch. Timer. Water listed at 200 m / 660 ft. That is a sports rating on a resin digital. It is not a dive computer. I would not treat 660 ft as permission to skip the manufacturer’s sport limits.
Listed weight: 58 g. Rectangular digital. Buttons. No touchscreen. No maps. Time, a stopwatch, and a watch that lives in a bag without pairing. No phone required. No companion app. No GPS track. No notifications. Years-scale battery language instead of a charger on the nightstand. If you want satellite lock and a training log, this is the wrong tool. That is the Garmin below.
In my taste this is the “cheap square, shock-resistant sports watch, leave my phone in the locker” pick. Confirm you are on DW-5600UE-1V and not a pricier colorway of the same family.

Garmin Instinct 2 Solar Graphite
When I checked in early September, the Instinct 2 Solar Graphite was in stock at $285.99. A second figure of $249.99 also sat on the same page. I am quoting both. Confirm which offer is actually in the cart before checkout.
Stars: 4.6 out of 5 from 798 ratings. Smaller pile than the G-Shock. Still a real sample. I would rather have 798 voices than a handful.
This listing is the smaller-sized Solar Graphite. Garmin also sells 2X cases and later Instinct 3 listings. Do not assume the photo is the 50 mm sibling. Match Graphite, Solar, and the smaller-sized name.
Solar charging is on the page with Garmin’s wording: unlimited battery life in smartwatch mode if you wear it all day and spend 3 hours per day outside in 50,000 lux. GPS-mode language: up to 48 hours with solar charging continuously in direct sunlight at 50,000 lux. That is a sun-and-settings claim, not a promise I can make for your week.
Fiber-reinforced polymer case. Scratch-resistant Corning Gorilla glass. Water listed at 100 meters. I treat 100 m as rain, a sink, and a pool. Not a diving course. Multi-GNSS: GPS, GLONASS, Galileo. 3-axis compass. Barometric altimeter. TracBack routing. Built-in sports apps for running, biking, swimming, strength, and more on the page. HIIT workouts. Smart notifications and Connect IQ when you pair a compatible phone. Bluetooth. Sunlight-readable display, listed at 1.27 inches.
Buttons. You do not need a touchscreen. Tracks dump into Garmin Connect on iPhone or Android. It is still a gadget. You charge it. You pair it. You live with satellite and battery limits. It is not a G-Shock square with maps glued on. I am skipping wrist-wellness copy. This is a consumer GPS watch, not a medical gadget.
In my taste this is the “buttons, solar, GPS tracks, I already live in Garmin Connect” pick.

How They Differ On The Wrist
Price first. An on-page $53.56 with a messy See All Buying Options screen versus $285.99 in stock, with $249.99 also on that Garmin page. Confirm the live offer on the square. Confirm which Garmin number is the cart.
Phone: the G-Shock needs none. The Instinct uses a phone for notifications, software, and dumping tracks. You can still run GPS without staring at a phone. You cannot skip charging the way you skip it on a Casio quartz digital.
Charge: years-scale battery language on the square versus Garmin solar and GPS modes measured in hours to days, depending on sun and settings. If you hate a cable, buy the Casio. If you will actually sun-charge or plug in, the Instinct is the tool.
Water: 200 m / 660 ft on the G-Shock versus 100 m on the Garmin. Neither replaces a dive briefing. Shock-resistant sports language is Casio’s job. Fiber-reinforced polymer and Gorilla glass is Garmin’s.
Shape: rectangular digital module versus a round Instinct case. 58 g on the Casio listing. The Garmin is the bigger presence on a small wrist. Measure. The listing I opened is the smaller-sized Solar, not the 2X.
Skip both if you want a round AMOLED, Wear OS apps, and phone notifications as the whole point. That is Galaxy Watch, Pixel Watch, Apple Watch. Different class. This post is the square tool versus the rugged GPS tool.
Who I Would Pick For Which Taste
I would buy the G-Shock if I wanted time, alarms, and a stopwatch with no app and no charger. Shock-resistant sports language. Cheap digital. 4.7 from 23,077. I would skip it if I needed GPS, a compass, TracBack, or a training log. I would also skip it if I refused to sort a messy buy box. $53.56 on the page is a number to check, not a promise.
I would buy the Instinct 2 Solar if I already live in Garmin Connect, I want GPS and ABC sensors, and I will charge or sun-charge the watch. In stock at $285.99 the day I looked, with $249.99 also on the page. 4.6 from 798. I would skip it if I wanted a watch that never pairs, never charges, and never asks for a phone. I would also skip it if I grabbed the 2X or an Instinct 3 by accident.
Bottom Line
Two live Amazon listings in early September. A G-Shock square, DW-5600UE-1V: cheap digital, no phone needed, shock-resistant sports watch, 200 m / 660 ft that is still not a dive computer, 4.7 from 23,077, and a buy box you have to confirm because See All Buying Options and $53.56 sat on the page. A Garmin Instinct 2 Solar Graphite, smaller-sized: in stock $285.99, a $249.99 figure also on the page, 4.6 from 798, solar and GPS battery language, 100 m, multi-GNSS, TracBack, buttons, Garmin Connect.
In my taste I would take the Casio if the whole point is a square I never charge. I would take the Garmin if the whole point is GPS tracks and a longer charge cycle than a phone watch. Confirm the model the day you buy. Prices move.
