Best G-Shock Watches (2026): Which Casio G-Shock to Buy

Featured image: Simon Le Bon, derivative work by Pittigrilli, Public domain, via Wikimedia Commons

The best G-Shock for most people is still the square Casio G-Shock DW-5600UE-1: about $100 at list price, 200 meters of water resistance, a five-year battery and the same basic shape Casio launched in 1983. If you want it to set itself and never need a battery, step up to the solar, radio-synced GW-M5610U-1.

G-Shock comparison table

Prices are approximate US street prices as of November 2026. Casio raised list prices across its US catalog by roughly 10% in September 2025, so older reviews often quote lower figures.

Best square and everyday G-Shocks

The square case is the G-Shock most people picture. Casio engineer Kikuo Ibe’s team released the first one, the DW-5000C, in 1983, and today’s 5600 and 5000 models still use the same hollow-module, shock-absorbing layout. Our page on the Casio G-Shock DW5600 covers its long run on screen.

Best overall: G-Shock DW-5600UE-1

The DW-5600UE-1 is the current version of the long-running DW-5600E-1V, and in the US Casio now sells the updated watch under both names. The look barely changed, but Casio swapped the old electroluminescent backlight for an LED and raised the rated battery life from about two years to about five, according to G-Central and Notebookcheck’s coverage of the update.

It weighs 52 grams, is rated to 200 meters, and has the usual stopwatch, countdown timer and daily alarm. US list price went to $99.95 with the update, but big retailers regularly sell it for less.

Who it’s for: Anyone who wants one G-Shock that does everything well enough and costs little. Trade-off: No solar and no automatic time setting, so it drifts a few seconds a month and you change the battery yourself.

Best value upgrade: G-Shock GW-M5610U-1

The GW-M5610U-1 is the same square silhouette with two upgrades that matter in daily life. Tough Solar charges the cell from any light, and Multi-Band 6 picks up radio time signals from transmitters in the US, Europe, Japan and China, so the watch corrects itself overnight when it is in range.

It is often called the most practical G-Shock: set it once, and in most places you never touch it again. After the 2025 price increase, Amazon’s listing settled around $140, up from roughly $100 before.

Who it’s for: Daily wearers who hate battery changes and want accurate time. Trade-off: Radio sync does not work everywhere (much of Asia, Africa and South America is outside the six signal areas), and there is no Bluetooth.

Best enthusiast square: G-Shock GW-5000U-1

The GW-5000U-1 is the square for people who already own a few. It uses a screw-down case back and a stainless steel inner case like the 1983 DW-5000C, rather than the four-screw back on the 5600, and runs on Tough Solar with Multi-Band 6.

It weighs about 74 grams and Casio America lists it at $330 after the 2025 increase. Inside, the function set is close to the GW-M5610U.

Who it’s for: Fans who care about the original construction and a more premium feel. Trade-off: More than double the price of a GW-M5610U for mostly the same features.

Best full metal: G-Shock GMW-B5000D-1

Launched in 2018 at $500, the GMW-B5000D-1 turns the square into a stainless steel watch with a matching bracelet. It adds Bluetooth to Tough Solar and Multi-Band 6, so it can set its time from your phone anywhere and lets you change settings through the Casio Watches app.

It weighs 167 grams, about three times a resin square, and G-Central reported US dealers selling GMW-B5000 models at $550 before the September 2025 increase. Expect roughly $550 to $650 today, with occasional discounts.

Who it’s for: People who want a G-Shock they can wear with a suit. Trade-off: The polished steel scratches, and the bracelet is heavy for sports.

Best analog-digital, outdoor and sport G-Shocks

Outside the square family, G-Shock splits into everyday analog-digital models and the “Master of G” tool watches built for land, sea and air. These are the standouts.

Best analog-digital: G-Shock GA-2100 “CasiOak”

The GA-2100 arrived in 2019 at $99 and quickly earned the “CasiOak” nickname for its octagonal bezel. At 11.8 millimeters thick and 51 grams, it is one of the slimmest, lightest G-Shocks, thanks to a carbon-reinforced resin case Casio calls Carbon Core Guard.

It combines hands with two small digital windows for the stopwatch, timer, alarm and world time. If you want solar and Bluetooth, the GA-B2100 adds both and launched at about $150, against $99 for the original.

Who it’s for: Anyone who prefers hands and wants something that passes as a casual sports watch. Trade-off: The small digital displays are hard to read at a glance, and the basic GA-2100 still needs battery changes.

Best for military and tactical use: G-Shock DW-6900

The DW-6900 is the “three-eye” G-Shock, named for the three ring graphics above the display. G-Central describes it as the successor to the DW-6600, a classic Navy SEAL choice, and has documented Navy and Marine divers wearing DW-6900s on duty.

It is thicker than a 5600, at about 18.7 millimeters, but it is cheap, rated to 200 meters and easy to read with its face-mounted light button. The current DW-6900U-1 has an LED light, and street prices have often been in the $60 to $90 range.

Who it’s for: Soldiers, contractors and anyone who wants a cheap, disposable-feeling beater. Trade-off: Bulky under a sleeve, and the base model has no solar or radio sync.

Best outdoor G-Shock: GW-9400 Rangeman

The GW-9400 Rangeman packs Casio’s Triple Sensor: an altimeter and barometer, a digital compass and a thermometer, with Tough Solar and Multi-Band 6. It also gives sunrise and sunset times, which matters more on a trail than most smartwatch features.

It is large at 55.2 by 53.5 millimeters and weighs 93 grams. US prices have generally sat around $330 to $400. Our G-Shock Rangeman page covers the Rangeman seen on Chris Hemsworth in Extraction.

Who it’s for: Hikers, hunters and anyone who wants sensors without a screen to charge. Trade-off: No Bluetooth or GPS; the GPR-H1000 Rangeman adds GPS at a much higher price.

Best premium tool watches: GWG-B1000 Mudmaster and GWF-A1000 Frogman

The GWG-B1000 Mudmaster launched in October 2023 at $800. It keeps the Triple Sensor, solar and radio sync, adds Bluetooth, and uses a mix of carbon-fiber-reinforced resin and forged metal to keep out mud and dust. It is 58.7 by 52.1 millimeters and 114 grams.

The GWF-A1000 Frogman is the first analog Frogman and carries an ISO 200 meter diver rating, which is a stricter standard than the usual “200 m” on other G-Shocks. Its carbon monocoque case and Tough Solar movement put it in the same roughly $800 bracket in the US.

Who they’re for: Buyers who want the toughest G-Shocks Casio makes and like big watches. Trade-off: At these prices you are close to a Garmin or a mechanical dive watch, and both G-Shocks are huge on the wrist.

Best for training: G-Shock GBD-H2000

The GBD-H2000 is G-Shock’s answer to sports watches: GPS, an optical heart rate sensor, a compass, altimeter, barometer, thermometer and step counter, charged by USB with solar assist. It launched in March 2023 at $399 and is often discounted to around $300.

Reviews are mixed. RunningShoesGuru concluded it needs real improvement to justify its price against dedicated GPS rivals, and other reviewers noted it cannot pair external sensors like chest straps. Battery life is about 19 hours in its long GPS mode.

Who it’s for: G-Shock fans who want basic run and workout tracking in a truly tough case. Trade-off: A Garmin Forerunner or Instinct does more for similar money.

Best G-Shock for military use

There is no official issued G-Shock. Casio’s own US site says its military-styled watches are not endorsed by any branch, and most service members buy their own. That said, a few models show up again and again in photos from the field.

The DW-6900 and the square DW-5600 family are the most common, mostly because they are cheap, light and easy to replace. Navy divers and special operations units have long favored G-Shocks, and the DW-6600 and DW-9052 appear in G-Central’s archive of service members on duty. Read more in our guides to military watches and what watch Navy SEALs wear.

For deployments, the GW-M5610U-1 is the smart pick: solar charging removes battery worries, and it weighs about the same as the basic square. If you need a compass and barometer, the Rangeman is the step up. Casio America also offers a 10% discount for military, first responders and medical personnel through ID.me verification.

How to choose a G-Shock

Start with power. Battery-only models like the DW-5600UE and GA-2100 are the cheapest, but solar models charge themselves from daylight and indoor light and are the better long-term choice if you can spend about $40 more.

Next, decide on time sync. Multi-Band 6 radio sync is set-and-forget in North America, Europe, Japan and China. Bluetooth models sync from your phone anywhere, which matters if you live outside those signal areas or travel often.

Then think about size. The square 5600 and the GA-2100 suit most wrists, including smaller ones. The DW-6900, Rangeman, Mudmaster and Frogman wear much larger and taller, which is the price of their extra protection and sensors.

Finally, ignore model-name noise. The letters after the number (such as -1, -1A1 or -1B) usually mean only a color or region code. If you want a broader look at digital watches beyond Casio, see our guide to the best digital watches.

FAQ

Which G-Shock is the best overall?

For most people the square DW-5600UE-1 is the best G-Shock, because it is cheap, light, 200 meter water resistant and now runs about five years on a battery; the GW-M5610U-1 is the best upgrade if you want solar power and automatic time sync.

What is the best G-Shock for the military?

The DW-6900 and the square DW-5600 or GW-M5610U are the G-Shocks most often seen on service members, since they are inexpensive and easy to replace, while the GW-9400 Rangeman suits roles that need a compass and barometer.

Is the G-Shock DW-5600 worth it?

Yes, the DW-5600 is one of the best-value watches you can buy, and the current DW-5600UE-1 improves on the old version with an LED backlight and roughly five years of battery life for about $100 or less.

Are solar G-Shocks better?

Solar G-Shocks are better for most daily wearers because they recharge from ordinary light and rarely need a battery change, though they cost roughly $40 or more over the battery-only version of the same case.

What is the most durable G-Shock?

Every G-Shock is built to the same shock-resistance standard, but the Master of G models such as the Mudmaster, Rangeman and ISO-rated Frogman add mud, dust or diving protection on top of that.

How long does a G-Shock last?

A G-Shock can easily last decades with battery changes and the occasional new strap, and solar models avoid most battery changes entirely, although the rechargeable cell can eventually wear out after many years.
