The G-Shock Frogman has been around since 1993 and has been upgraded multiple times to keep up with modern technology from the first to the current 5th generation. It is one of the earliest watches from the Master of G series – the line was developed specifically for professional-grade use such as military, divers, and so on.
Casio G-Shock Frogman GWF1000-1 watch is the latest update for the Master of G Frogman line. Like other Frogmans of the past, this watch is designed specifically for pro scuba divers. They’re highly collectable, so even non-divers invest in Frogmans with each release.
The G-Shock Frogman demands attention. At over 50 mm wide and 18 mm high, the 115-gram Frogman is easy to spot among other G-Shocks because of its unique asymmetric shape.
It is made with heavy-duty, stainless steel case, bezel, and crown – all of which are given diamond-like coating (DLC) for extra corrosion resistance.
Durable materials don’t stop there – the latest Frogman model features non-reflective, scratch-resistant sapphire crystal and carbon-fiber-reinforced wristband.
A few highlights of the Frogman’s design include:
- Well-placed buttons – Right-side buttons are large and easily pressed, which seem to be intended for use when underwater, while the left-side buttons are circle-shaped and buried into recessed rubber guards.
- Caseback – Somewhat glossy but made with DLC-coated stainless steel, the caseback features the robotic frog logo embossed at the center.
- Strap – The 2-layer neoprene and carbon fiber strap shares asymmetry with the case, which is a nice touch. It also won’t slip off underwater ever, since the strap is attached to the case with four Allen screws.
- Perfectly-protected hardware – An inner container protects the timing module 3445 and then enclosed with full stainless steel.
- Large-sized – If you’re new to Master of G watches, you’ll be surprised at how huge the Frogman is. But by G-Shock standards, the Frogman’s 59.2 x 53.3 x 18.0 mm measurement is actually wearable thanks to its 141-gram weight.
- Unidirectional Bezel – The Frogman’s bezels rotate counter-clockwise, which helps divers check how long they’re been underwater and safely go back to the surface before air runs out.
The G-Shock Frogman can withstand salt water – one of the most corrosive elements for watches. To combat this, Frogman uses a mix of stainless steel, rubber and hardened crystal glass. The size of this watch, which is larger than day-to-day watches, makes it easy for divers to wear even on top of their scuba gear.
The G-Shock Frogman is a watch built for scuba divers in mind, but unlike other watches that claim to be water resistant, the Frogman actually has ISO-rated for 200 meter professional diver rating. Other notable features of this exceptionally sexy watch include:
- Tough Solar Power – -The Frogman doesn’t need recharging or replacement. Its solar rechargeable battery can survive up to 10 months on a full charge without further exposure to light.
- Full Auto EL Backlight with Afterglow – Like the Rangeman, this G-shock model has auto backlighting, which users can turn off, or set-up for 1.5-second or 3-second illumination.
- Moon and Tide Data – Ideal for fishing, surfing, and diving, the 7-segment tide graph and moon phase helps in checking accurate tide data. You can set it up with your UTC offset or lunitidal interval. The moon data displays moon age of the specific data and moon phase graph.
- Dive Recording/Measurement Functions – The Frogman has a dedicated dive mode, which users can access by pressing the lower-left button for a couple of seconds. It comes with a digital ISO 200M WR Dive Timer, which measure dives up to 24 hours and surface intervals of up to 48 hours. Users can even check the last 20 diving data, which is stored on the built-in memory.
- Full Auto-Calendar – It features a full auto-calendar, which is pre-programmable until the year 2099 with 12/24 hour formats and accuracy rate of +/-15 seconds per month.
- Triple Sensor Technology – This tech includes an altimeter (altitude measuring sensor) to replace a GPS if needed, barometer (atmospheric pressure measurement) for predicting weather using barometric pressure, and thermometer for accurate temperature readings.
- Basic G-Shock Features – G-Shock Frogman is also equipped with the basic features of most Casio watches, such as world time, 4 daily alarms, 1 snooze alarm, hourly time signal, 1/100 second stopwatch, Countdown timer, battery power indicator, power-saving function, and button-operated on/off switch, among others.
Other scuba-specific functions include depth gauge (track depth), and water temperature. It’s fully-featured for scuba divers, but the Frogman isn’t recommended as a substitute for actual dive gadget. As a back-up, it would do.

The most widely complained issue about the G-Shock Frogman is its expensive price. If you’re not aware of its story, it’s common to feel this way, but once you understand its value as a collectible and markup prices of second-hand “limited editions,” you’d be one of these people lining up to get one (even if you’re not a diver).
In addition, Frogman is highly customizable with over 100 setting available, which is why there’s a learning curve. If you bought the Japanese version and (unluckily) got a Japanese guide as well, this can be very frustrating.
The G-Shock Frogman GWF-D1000B was made for professional divers, but even simple watch lovers who appreciates specialty functions would fall in love with the Frogman. It’s classic, feature-packed, and is made with high-quality materials like anti-corrosive DLC coating and shock-resistant case that lets you enjoy the watch for decades.
As with other Frogmans in this Master of G line, you’ll get a perfect combination of features and technologies from G-Shock and Casio. It’s a very good value for money, considering its high demand from collectors around the world.
