5 FROGMAN recommendations for divers' watches
FROGMAN is perfect for diving and marine sports. The design is also a nice accent when worn during activities as well as in everyday life. Here are some models that can be used for both diving and daily use.
(1) Long-selling model "when you think of FROGMAN
From FROGMAN, which supports underwater missions, this is a very popular model that has been loved by many since its launch. The DW-6300-1A model was the first G-SHOCK with ISO standard-compliant water resistance down to depths of 200 m. Log data memory, tide graph, and moon data functions are also included. Larger stopwatch control buttons for reliable operation even underwater. The fully-automatic EL backlight emits a brilliant light on the LCD simply by tilting the arm, even while diving. The asymmetrical design of the asymmetrical left-right sides, which is the symbol of FROGMAN, is a striking piece.

(Male in his 40s) The best frogman
I have purchased and used various Frogman models since the first generation, and I like this model the best of all the Frogman models!
(Male in his 50s) Satisfied with both design and texture
With the number of digital watches decreasing, digital diver's watches are valuable. It is a little too thick for everyday use and not suitable for wearing with a suit, but it is suitable for town use and diving.
(Male, 50s) Frogman
G-SHOCK's undisputed tough body, functionality, and, best of all, recognizability are at their best. The operability is also perfect.
FROGMAN's first full analog model
This is FROGMAN's first wristwatch to feature a full analog model. The asymmetrical face design features home time, dual time display, and diving time measurement all in analog. The large luminescent hour and minute hands enhance legibility.
It features a carbon indial that takes advantage of the characteristics of indial solar in a carbon monocoque case formed of an integrated case and back cover. Reinforced resin with carbon fiber boasts high water resistance and strength, and has achieved ISO-standard 200m water resistance capability. The material's characteristics are also utilized to reduce weight and improve wearing comfort. The band is made of "fluoroelastomer," which has excellent antifouling and hydrolysis resistance, in anticipation of hard use in the sea. It is designed to withstand harsh environments.
The CASIO WATCHES smartphone app can be used to easily set tide data for approx. 3,000 locations around the world. You can also check the diving log on your smartphone and view data measured by the watch in more detail.

Customer reviews of GWF-A1000-1AJF
(Male in his 60s) Generally good
It has both practicality as a diver's watch and as an outdoor watch, but it is still highly practical as a diver's watch. I think the long watch band also assumes the diver suit is worn. Therefore, for general outdoor wear, it is better to replace the belt for a better fit. I would have liked to have had a shorter belt, but I think this watch is specialized for a diver's watch.
(Male, 50s) Frogman
I like that it is analog.
(Male, 40s) Purchased for daily use
It's been about 3 months since I bought it and so far I have been using it with no problems and am satisfied with it.
(3) FROGMAN's first composite band
FROGMAN's first composite band is easy to put on and take off and has an extension function on the center detent to make it easier to wear over a wetsuit. It can be fine-tuned to fit perfectly without the need for tools, and can usually be folded down to a comfortable length. A smartphone link-up function links to a dedicated application for easy automatic time correction, world time time display, and dive log display.
The highly visible face design allows the wearer to check the time at a glance, and the blue on the stainless steel bezel and yellow on the second hand are perfect for the daytime sea. As a well-designed and stylish watch, it can be incorporated into both diving and everyday use.
Customer reviews of GWF-A1000C-1AJF
(Male, 50s) I like it very much.
I was eagerly awaiting the release of Frogman's Analog. It's cool.
It is comfortable to wear and does not feel as heavy as it looks. I want to use it for a long time.
(Male, 40s) It has become one of my favorites.
My motivation for purchasing the watch was because I was looking for an "easy" watch. I am a regular user of mechanical watches and own a good number of them.
A watch that lets you play to your heart's content without worrying about anything off...
Tough, unstoppable, no sun difference, and no maintenance costs...the candidate was Frogman.
There are pros and cons to this change to analog, but for a watch lover like me, digital watches don't fit the bill. If it had remained digital, we would not have purchased it. The large size makes it very legible, and the dial design is excellent.
Because a watch is packed with such a large amount of information, it tends to become a messy, unorganized dial that is difficult to read if it is not handled properly. The indexes and hands are matte finish without metal material, which also ensures good legibility. A watch that uses half-finished metal materials and produces a cheap glare is the worst, and I don't want to wear it.
Personally, I also like the design of the hands.
Carbon is used as the material, so contrary to its apparent image, it is very light.
The advantage of composite bands is that they can be adjusted just right against the wrist.
I don't like rubber belts because too much "excess" can be unsightly.
I also liked the unique extension feature.
It is not a luxury watch (I am not looking for luxury in a G-Shock), but the quality is very high. It is full of "attention to detail" and carefully finished. Depending on the TPO, this watch is not embarrassing for an adult male to wear.
It is overspecified for most people, but I think that is part of the attraction that draws them in.
If you are interested in this product, please see and touch it in the store. There is always something that cannot be conveyed just by looking at a picture.
(Male in his 40s) Feeling uplifted
This wristwatch gives a mechanical impression.
When worn, it motivates and lifts the mood.
I don't often get a chance to use the dive mode.
The movement is interesting to watch.
I like the robustness and presence that this watch exudes.
FROGMAN, which is thoroughly focused on the specifications demanded by divers
FROGMAN (diver's watch) is equipped with a triple sensor that measures direction, temperature, and depth. The azimuth indicator is equipped with an automatic horizontal correction function, enabling correct azimuth measurement even underwater where the posture is unstable. Depth measurements down to 80m, which exceeds the limit of diving activity, are made in 10cm increments. Developed with reference to the voices of professional divers, it also has excellent shock and abrasion resistance.
This diver's watch is designed for professionals, with large forged buttons that ensure operability even while wearing gloves, a long band with carbon fiber sheet inserts, and a high-intensity LED light to support activities in dark areas.
Customer reviews of GWF-D1000B-1JF
(Male, 40s) I saw the finished product.
I had been eyeing a Frogman for a long time, but since I was wearing an empty Master as my main watch, I spent most of my time looking at it sideways, but when I was allowed to touch it at a watch shop, I fell in love with it all over again, its high degree of perfection, the solidity it feels, the asymmetrical design that has never changed, and I purchased it on the spot. I fell in love with it all over again and bought it on the spot.
I am not a diver or anything, just a human being, but it made me feel the joy of ownership for the first time in a long time.
(Male in his 60s) Always accurate ibo for multiple uses.
Since it is an ISO-standard diver's watch, it can be easily washed and used in a clean condition even if it gets dirty due to sweating in the sea. If I leave it by the window at night, it automatically sets the time and always shows the correct time, which is very convenient. I use it for both play and work. The only drawback I can think of is that the belt gets caught on too many clothes.
(Male, 40s) The color is cool.
The blue used at points is very nice and cool.
The functions are too multifunctional to be of much use, but they tickle a man's fancy.
5) FROGMAN of a higher grade that makes abundant use of carbon
FROGMAN carbon composite band model. The bezel is made of lightweight, highly rigid carbon material that incorporates cutting-edge TORAYCA® Carbon Fiber*1 and NANOALLOY® technology.*2 The band is also made of a lightweight and highly durable carbon composite band, with particular attention to detail. Extension mechanism on the center clip for easy wearing over a wetsuit. Folds down to a comfortable length for normal use.
The use of orange on the dial adds a distinctive touch. This frogman can seamlessly switch between everyday life and diving scenes.
Customer reviews of GWF-A1000XC-1AJF
(Male, 50s) Heavy texture
I was not sure if I would like the standard model or not, but I am glad I chose this one.
The carbon composite belt and extension mechanism are also unprecedented parts of the product.
I like it very much.
I am also satisfied with the peace of mind of the radio-controlled solar power supply.
(Male, 60s) Value more than a wristwatch
It always has accurate time, good visibility, tough environmental characteristics, and is exceptionally well-balanced and heavy when worn on the wrist.
I think the quality of the appearance is also good.
(Male, 60's) Very nice!
I have owned several previous generations of models and I think it is the best quality ever. The price seems to be reasonable, but I am satisfied with the sense of ownership. In particular, the titanium belt and the texture design of the main body are definitely worth seeing in person.
(Male, 60s) We are always together.
I use it for both work and play. The G-SHOCK's shock resistance, water resistance to 200 meters, legibility that can be read at a glance, and linkage with a smartphone ensure that the time is always accurate. The metal and carbon belt is also easy to wear and conveniently adjustable in length according to clothing.
Here are some recommended models for those who do not require specialized scuba diving but want to enjoy skin diving (bare diving) and other activities.
4 recommended G-SHOCKs for skin diving
Here are four G-SHOCKs recommended for skin diving.
(1) Skeleton looks good on the sea
The "G-SHOCK 40th Clear Remix" series was introduced as G-SHOCK's 40th anniversary model. This is a new watch for July 2023. It is equipped with features useful for marine leisure and marine sports, such as a shock-resistant structure and a high-intensity LED light that ensures visibility in the dark.
The skeleton (clear color) model uses transparent material not only for the exterior but also for the LCD. The engraving of the 40th anniversary logo on the back cover makes this piece a collector's item.
Transparent clear colors are perfect for summer. How about an accompaniment for summer leisure time at the beach, pool, or outdoors?
2) Purple color will accentuate your coordination.
This skeleton (clear color) model expresses a retro look reminiscent of Y2K. The bright primary colors are ideal not only for marine leisure activities but also as accent colors for everyday coordination. The unique and eye-catching design will provide an opportunity to lift your spirits.
(3) Sports model perfect for activities
From G-SQUAD, G-SHOCK's sports line, this watch is equipped with features that are useful for everyday training in addition to its practicality. Since metal material is used for the face part, it can be worn in business scenes and suit styles without discomfort.

Why not make your own original wristwatch, the only one of its kind in the world?
Two diver's specification models recommended for daily use
Finally, here are some models designed for diving and marine sports. The design of this model is particularly high, making it ideal for daily use.
1) Standard sporty model
This is a metal analog model with marine sports specifications.
The model is water resistant to 20 atmospheres, so it can be used for marine activities such as surfing and bare diving. The back of the watch has a highly confidential screw back and a unidirectional rotating bezel. The standard sporty design makes it convenient to have one for a variety of occasions.
Customer reviews of MDV-107-1A3JF
The cost performance is good.
I wanted a diver's watch for the sweaty summer season. The belt is another thing, but the watch is solid, has good visibility, and I like it.
Memories Clock
I thought it would be easy to see and have an impact.
(2) Cool blue for a fresh look
This is another metal analog model with marine sports specifications. The watch is water resistant to 20 atmospheres, has a unidirectional rotating bezel, and a screw back for convenient use in marine activities. The blue color of the second hand as well as the bezel is distinctive, making it a refreshing piece to use.
Customer reviews of MDV-107-1A2JF
It looks more expensive than it is.
It may be classified as a cheap Casio, but I think its texture, weight, water resistance, and time accuracy are equal to or better than a diver's watch costing tens of thousands of yen.
I am very satisfied with the watch, which is very cost-effective because it looks elegant without being obnoxious.
The overall width is 44 mm, which is large, but since it is a diver's watch, I think this is fine.
It is also nice to know that the MDV-106, one of the earlier types of this model, is that Bill Gates' favorite watch, which satisfies the desire for ownership.
Good tints.
I bought it as a substitute only for the overhaul period of my watch, but I like it because of its color and luster.
Ideal for everyday use
Only 20 days have passed since I purchased the watch, but so far the time deviation is accurate to "(+)1 second".
It is a simple design, not cheap-looking, and looks proud on the arms of summer clothes.
Even though I use it almost all day long, it is not heavy and fits nicely (I take it off when bathing and sleeping).
Actually, I'm thinking of replacing it with a stainless steel band. I have a little bit of a feeling that this is a good idea, but I can't find the right product.
I am not in a hurry, but would appreciate it if you could sell me a genuine Casio replacement stainless steel band.
The actual product is more elegant in its shine than the picture, and is perfectly fine for business occasions. I think it would make a great gift.
In any case, highly recommended!
Attraction of Divers' Watches
What is a diver's watch?
A diver's watch is a wristwatch with specialized functions for diving. Suitable for diving and other marine sports. A diver's watch is defined by ISO (International Organization for Standardization) and JIS (Japanese Industrial Standards) as "a diving watch designed to withstand diving to a depth of 100 meters or more and equipped with a measurement system that enables the diver to read the dive time in the dark. requirements for the safety of divers. Diver's watches that have passed strict standards are reassuring buddies for those who are about to start diving in earnest or are looking for a watch that can be worn for diving.
Attraction of Divers' Watches
The diver's watch is one of the most attractive design features, embodying functional beauty. In addition to its high water resistance, the watch is equipped with a variety of functions that are particular about details such as a highly visible dial that allows the wearer to check the time even in the dark, a heavy case to withstand shocks, and a rotating bezel that allows the wearer to grasp the dive time and remaining cylinder time, making it safe to wear not only for diving but also for marine sports in general. It can be worn not only for diving but also for marine sports in general.
Some of the watches have stylish designs that can be used not only for marine sports but also for multiple purposes, from rough casual style to business situations. Wearing a diver's watch on a daily basis can be a great conversation starter with people who share common interests.
Diver's Watch Essential Features
Waterproof performance
Water resistance is the most important factor in selecting a diver's watch. As mentioned above, a diver's watch must be water resistant to a minimum of 100 meters. For general leisure diving, the maximum depth is considered to be 30 to 40 meters, so water resistance to 100 meters will not be a problem. However, for deep sea diving or saturation diving, a waterproof rating higher than that is required.
About the waterproof notation
Water resistance is described in terms of atmospheric pressure (BAR/ATM) for watches for daily use, and in terms of diving depth (m/ft) for diving watches. When water resistance exceeds 20 atmospheres, the unit of measurement is changed from "atmospheric pressure" to "diving depth," and the watch is specialized for diving. For this reason, divers' watches are often marked with a diving depth notation.
*Difference between 20 atmospheric pressure waterproofing and waterproofing for 200m diving
Since "20 atmospheres" is equivalent to "200m depth," isn't it the same waterproof performance? But note that the meaning is different.
- The "20 atmospheric pressure water resistance" means that the watch can withstand water pressure of up to 200 meters (approx. 20 atmospheres) when it is submerged in a slow, stationary state. Therefore, it is not intended for use in deep diving activities or work.
- As the name implies, the "200-meter submersible" can be used for diving to 200 meters. When diving, be sure to wear a diving wristwatch that has a diving depth indication (m/ft).
*To learn more about water resistance for daily use, please refer to this article.
Unidirectional bezel
The rotating bezel is a feature that allows the user to keep track of the amount of oxygen remaining in the oxygen cylinder by keeping track of the elapsed time during the dive. If the rotating bezel should go backwards, the exact diving time will not be known, which could lead to a life-threatening accident. For this reason, divers' watches are equipped with a "unidirectional rotating bezel" that rotates only in one direction to prevent malfunctions when measuring dive time. Even if the model does not have a unidirectional rotating bezel, the ability to check the dive time would be essential.
Ensures visibility in the dark
Since diving is an underwater activity in which light is difficult to reach, the readability of watches in the dark is one of the most important points to be considered. The dial should be large, and the indexes and hands should be coated with luminescent paint or equipped with a high-intensity LED light so that the time can be easily checked at a glance even in the dark.
Functions for professional divers and serious divers
Helium outlet valve
The helium ejection valve is a function that ejects helium that has entered the watch out of the watch. A mixture of oxygen and helium gas is used for saturation dives and other deep-sea dives. If the small molecule of helium enters the watch and is not discharged, the watch cannot withstand the high pressure and may expand and explode. To prevent this, a functioning helium discharge valve is required.
Some models are not fitted with bubbles, and it is important that they have the necessary mechanisms to protect divers, such as special gaskets that do not allow helium to enter, and a strong case and wind shield.
Band with extension mechanism
With a wetsuit on, the arm circumference will be thicker than usual because of the blistering. Therefore, a watch that can be worn under normal circumstances may not be worn when wearing a wetsuit. In such cases, a band with a two-stage adjustable extension allows you to adjust the length of the band to just the right size, whether you are wearing a wetsuit or on the street.
How to Choose a Diver's Watch
Divers' watches are equipped with functions to protect their lives and to enjoy marine sports such as diving and surfing. If you are thinking of taking up diving seriously, what criteria should you use to select a watch?
Since the water resistance and pressure resistance required for divers' watches vary depending on the application, it is important to first confirm that the watch has the appropriate functions.
For scuba diving, waterproofing to 200m is all that is needed.
For scuba diving, which is generally enjoyed as a hobby, a watch that is water resistant to 200m will be safe to use.
However, even divers' watches can be affected by changes in atmospheric conditions, water temperature, and water pressure, which can affect the display and performance of the watch. To save lives, it is necessary to use a residual pressure gauge, depth gauge, and other diving equipment in combination.
For dives deeper than 200 meters, there is a method called "technical diving," which uses a mixture of helium, oxygen, and nitrogen gases. Since some diver's watches are designed for saturated diving or highly functional models with water resistance of 200 meters or more, it is necessary to consider those that are suitable for diving depths and purposes.
The term "scuba diving" is sometimes used, but the Japan Scuba Association is promoting unification of the term "scuba diving," and we use the term "scuba" as well.
10 atm waterproof for skin diving
If skin diving (bare diving) without oxygen cylinders or other underwater breathing apparatus, 10 atmospheric pressure waterproofing can be used. In addition to skin diving, the wearer can also enjoy marine leisure activities such as windsurfing and water skiing while wearing the garment.
All G-SHOCK models are water resistant to 20 atmospheres and feature shock-resistant construction. Because it is a tough watch that can be trusted underwater, it is highly recommended for those who want to enjoy marine sports and marine leisure activities to the fullest.
If you want to use it for everyday use, you can also choose it by design.
Because divers' watches are expected to be used in extreme conditions, many of them are uniquely designed with reliability first, sturdiness and thickness second, and large dials. Because of its unique and robust design, it is very popular even among non-divers. The "real thing", made for those who challenge the limits, will give you energy for your daily work and daily life. There are many variations of diver's watches in terms of case and belt materials, dial design, and coloring. When choosing a diver's watch for everyday use, focus on lightness, comfort, and most importantly, a design that suits your style. This allows divers to enjoy divers' watches in everyday life.
