Description

The Casio G-Shock G-100 is a study in doing more with less. Launched in 2000 and still going strong, it distills the G-Shock philosophy — toughness, reliability, legibility — into a medium-sized round case that manages to feel both classic and purposeful on the wrist. The all-black resin case and band give it a clean, no-nonsense look, while the analog dial with Neobrite luminous hands delivers the kind of instant time readability that digital-only watches can't match at a glance. This is a G-Shock for people who appreciate straightforward utility without compromise. Under the surface, the G-100 is built on the three pillars that define the G-Shock line. Shock resistance protects the movement and crystal from drops and impacts. Anti-magnetic resistance shields the movement from interference by magnetic fields — a real- world concern for anyone working near motors, speakers, or industrial equipment. And at 200-meter water resistance (20 ATM), it far exceeds what most daily wear watches offer — fully capable of swimming, snorkeling, and extended submersion well beyond everyday splashes. The electro-luminescent backlight with afterglow activates at the push of a button for instant display readability in low-light conditions, and Neobrite coating on the hands ensures the analog display glows in the dark for hands-free time reading. The feature set is intentionally focused. Dual time lets you track a second time zone simultaneously — practical for travel or remote work. The 1/100-second stopwatch covers elapsed time with precision up to 23:59'59.99"", and a daily alarm with hourly time signal handles basic scheduling needs. An auto-calendar and selectable 12/24-hour format round out a clean, no-frills package. Powered by a CR2016 battery rated for approximately 3 years and housed in a mineral glass-protected case measuring 49.6 × 47.8 × 15.7mm and weighing 65 grams — the G-100 is a watch that earns its place on the wrist every single day. CasioWith the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

    • Fantastic G-Shock Watch
I had recently purchased the Casio F91W but returned it when I found this watch on Amazon. I had never owned a G-Shock watch before, however, I did know that they were good watches with an excellent reputation. I have small wrists - about 6 inches - but still wanted a G-Shock watch, even though most of their case sizes are 50 mm and above. This watch has around a 40 mm case diameter which is perfect for my wrist without being too large and bulky. The watch is quite thick - about 13 mm - however, this isn't a real problem considering how durable it is and the fact that I sometimes forget it is even on. The band is made of resin which feels a bit like rubber but without the stickiness. The case is also supposed to be made out of resin and it feels very rugged and durable. It is a G-Shock after all. The buttons seem to be made of metal and have just the right amount of give. Some people have complained about setting the analog watch hands. To set the watch hands, I pressed the top left button until the watch hands matched up with the current time. Unlike the other buttons, the top left button barely sticks out and is very hard and uncomfortable to press, however, you won't be resetting it often, as it is very accurate at timekeeping with a quartz timekeeper. For something that I would only have to do maybe once or twice a year I don't see it as a problem. In fact, I see it as a good thing since it won't be accidentally pressed. The watch face protector is hard and appears to be glass. The digital face can be setup to either show the date or the time down to the second with a few button presses. It can also be used as a stopwatch, an alarm, or to show another time from another time zone. The alarm beep is also pretty loud, which is a plus. The one feature that is missing is a timer. On my old Shark Classic watch there was a timer function with a few preset durations. I still think that that is a minor problem, however. As opposed to on my Casio F91W, the watch can be easily read in the dark. The analog hands and hour tick marks glow green in the dark, and the digital face has a green light which can be activated with the bottom right button for around 2 seconds at a time. The watch also features 200 m water resistance, which is more than enough for 99% of people. The watch also features magnetic resistance, which should protect the timekeeper from being thrown off by magnetic fields produced by electronics. My only real complaint is that when the minute hand is between 20 and 40 minutes it partially blocks the digital watch face, but that isn't much of a problem in my opinion. For $50, this is a fantastic watch. It looks great, functions well, and has the reputation of Casio's G-Shock lineup. All in all, I would definitely recommend this watch. Pros: - Looks great - Durable - Right size for me - Made of quality material - Easy to read at night - G-Shock reputation Cons: - No timer - Digital face sometimes gets partially covered. - Analog and digital watch face ... show more

    • Great watch for what it does, but description is very flawed.
I love my own Casio G-Shock watches, so when I was looking for a gift for my nephew's birthday, I looked at a lot of the different G-Shock watches here on Amazon.com for him. My nephew is in the Boy Scouts, and when I found this watch and read in the description that it has a compass, it made me decide to go ahead and order it, because I know he would love that feature, as well as the rugged good looks and durability of the watch. The description is/was as follows: "Round-face watch in resin with accurate digital compass around bezel, textured band with gunmetal-tone rivets, and logo emblem at twelve o'clock Mineral crystal dial window Features buckle closure, 100-hour chronograph, and compass with bearings based on 16 cardinal points measured in degrees Water resistant to 660 feet (200 M): suitable for recreational scuba diving" This is clearly a misrepresentation of what people will get when they purchase this watch. I would return this watch to Amazon and purchase one elsewhere, but his birthday is going to be celebrated this weekend, and time is running out. This is clearly an issue with Amazon's product description. With that said, the watch itself is representative of the high quality that I have come to expect from the Casio G-Shock line of timepieces. I am sure that it will make a fine gift for him and prove to be as rugged as my 12 year + Original G-Shock solar atomic watch that I wore at work and beat up pretty good, but it still functions perfectly. I had to rate the watch 5 stars based on the functions and durability it was designed for, and think it would be inappropriate to rate the product itself poorly because of an error in product description by Amazon. The watch is not what I was led to believe it was when I ordered it. Come on Amazon! Please address this inaccurate description and update it to provide factual details regarding its functionality. It is a fine watch, worth the price, but setting up expectations of certain features and then delivering a product that does not match the description is a disappointment and affects the trust of Amazon by its consumers. **Edit** 04/29/2015 To clarify, this watch DOES NOT have compass functionality, nor is it solar powered. It is a rugged G-Shock with analog and digital display with the usual stopwatch, dual time, alarm, etc., and the LCD display is "negative" - black background with silvery digits, which adds to its appeal in my case. Very nice watch, good price for what you get. The MSRP is $100.00, but I purchased it from Amazon for around $58.00. ... show more

    • Perfect G-Shock
After wearing a cheap Timex with a nylon band for a couple years, I was in desperate need for a new workout watch. I was looking for something with a stop watch for timing jogs, but didn't sacrifice on looks. This G-Shock is perfect. Early on in the search process, I decided to go with a G-Shock over a Nike, Puma, etc workout watch. I don't need the GPS tracking mode and felt the G-Shock had a better overall reputation for reliability. I've not been disappointed. It's the little things. For instance, the plastic bezel sticks out on the front so if it ends up on its face, it won't get scratched. You can replace the band if it gets screwed up. Before purchasing this watch, I read a lot of reviews and looked at a lot of G-Shocks in the store. This one received criticism for two primary things. 1. You have to hold a single button to advance the minute hand. That's the only way to set the time. 2. When the hands are between :20 and :35, it's hard to read the digital display. On number one, it's true, you have to hold a button to set the time. It's annoying .... once a year, when DST is over. On number two, I haven't noticed this to be irritating at all. Perhaps if you have problems seeing close up. Oh, and yes, the light only lights up the small digital display, but the watch hands glow in the dark. So, no issues telling the time in the dark. The biggest reason I got this watch is it's an affordable analog/digital watch. I love the look of analog, but enjoy the digital functionality. This one combines both in a very attractive package. I've worked out many times with it. It does not collect sweat or smell afterwards. And, it looks good enough for a business casual function. Are there nicer looking G-Shocks out there? Sure. But, for the price, you can't beat this one. (Also, no issues with the water resistance. I've had it in the shower and frequently do dishes with it on. Granted, it's not diving, but still, no water has infiltrated the face.) Update: I've now been wearing this watch daily since I purchased it in 2012. It is functioning 100%. Even more impressive, there are no scratches on the face. I cannot say enough about how nice the plastic bezel is. It does a great job protecting the face -- as is evidenced by several scratches on the plastic. The plastic band is still perfect also. Lastly, no battery replacements in that time. This thing is freaking awesome! And, it's under $60! ... show more

    • Ups & Downs
This Analog/Digital Combination Watch is a Great Buy & there's more Ups than Downs if you ask me. 1st off its your Standard Watch Size & is not as Big as the Pics make it seem to be. The Style is Very Nice & has that Rugged Look & Feel to it. This Watch is made to withstand an Hard Active Lifestyle. Its Clear to see it can take some Abuse without being Harmed Thanks to the Materials. The Analog is Slightly Useless in the Dark seeing that you can only Truly Read the Hour & Minutes Hands. You would think the Numbers or Dotted Arrows for each Hour would Light up as well but they Don't Provide enough Light to Consider it as Help (In Complete Darkness). You Basically have to know your Timing based off of those 2 Hands only. The Saving Grace to Counteract this is the Digital System in the Watch. The Led provides the Light Source to Cover for its Flaw on the Analog. The Digital System also Comes with your Standard Feature Settings (Calendar, Time, Alarm, StopWatch & Dual Time). So its all sorts of Handy when you look at it. Also because of the Analog, Digital & Dual Time Feature you can now Keep the Time for 3 Different Events/Zones all at once. The only Flaw with the Digital is that from the 20Min Marker up to the 40Min Marker its Blocked when the Analog reaches around those Times (Its Not That Bad But Still). One More thing is the Setting Up of your Watch which can be a Pain the 1st time & if you have to Reset your Watch for what ever reason. The Buttons are a bit Hard to Push (One In Particular) & Holding them during the set up is not Nice lol. The Biggest Pain during set up is the Analog Clock which can Only Advance & can't Reverse. It Advances by 20sec per push or can be Held for a Auto Advancement but Don't go pass the time you want or you'll have to go pass all the Hours again just to reach back to where you belong. The Watch is Crafted to have a Great Appearance/Design but it has Ups & Downs. Yeah there's a few Problems due to the Design but the Mechanics/Materials of the Watch is Top Notch. Its of the High Quality you would expect from Casio with its Strong Build. ... show more

    • Reliable, Comfortable, asthetically appealing.
Initially I was looking to purchase a Luminox navy seal dive watch but I refrained because of its price. The main thing that attracted me towards the Luminox watch was its durability. I wanted to purchase a watch that could withstand the risks of day to day wear in all conditions (outdoors, exercising, everything). I am thoroughly impressed with this product. 1) Super light weight. I was concerned at first because I thought it would be bulky and heavy. It is surprisingly light and has a very solid feel to it. The band is very comfortable and strong. I've sweated in this thing several times and it does not leave a nasty smell like the leather bands. 2) Looks good. I can wear this while working out, going downtown, with any business casual attire. It is CLEAN! I have gotten numerous comments about it too. 3) Durable. I have already banged it into desk corners, door jams. It has been with me during drunken nights. I can be pretty wreckless with it and not have to worry about damage. (this is super important...if I bought the Luminox watch, I would be super protective about it not because of questionable durability, but because I spent a ton of money on it). 4) Easy to use. Setting the time, adjusting time zones. Super easy. Potential problem areas: 1) Setting the time requires you to hold a button down and it only moves in one direction. It takes a little while longer to set the time initially but in my opinion it is not a big deal at all. (maybe like another minute or two of your time max). 2) Because this is primarily an analog watch, it does obstruct the digital aspect of the watch at certain times. Not a big deal to me because you can still read it if you tilt the watch a certain direction. If your really invested in using the stopwatch, another timezone, or anything related to the digital function, I would recommend purchasing a DIGITAL watch. ... show more

if you break this watch there is a good chance your wrist is in pain. i own lots of watches and i have many stainless dive watches that look tough and fancy. none can hold a candle to a g-shock. ever. that said, a huge production environment is bound to put out a couple mistakes. it happens. exchange it for a new one if possible. i own one of these watches. its not small but it doesnt look too bad on my little wrist. the light doesnt light up the dial-only the digital read out.that doesnt matter too much to me because the lume on the hands stays lit pretty well. the buttons are hard to push for a very good reason-you dont want them to get pushed unless you mean it. in an active environment , this is the way to be (for me at least). the hands stay where they are supposed to...there are some sport watches out there that are cheaply built and the hands will "slip" if the watch is knocked around (im looking at you pulsar) let me explain the title of this review here. some people my think that because this watch is made out of plastic that it is low quality. not true in this case. this is a tank of a watch. you could probably run it over with a bread truck and it would be ok (dont try that). i am a pipefitter and have had one of these for 2 years and it looks brand new and has never failed me. great price too! casio did not fool around when they built this. we asked for it-they built it. if you want a watch that will impress your friends at dinner this might not be it. if you want a well engineered,simple watch that will impress you....this is it. fresh battery every few years or so and youll be pleased as me. edit: i now have 2 of these. one is all black and factory and one is navy blue with a black bezel. i bought the blue one on x-bay and tore it down and refurbished it inside and out. i put a horrible picture of it here. its the one in the bush. ... show more

This was one of the first G-Shock watches I purchased. I have a 6 3/4" wrist, so I wanted a rugged, durable, and sensible watch that fit me. A lot of the newer G-Shock Classic watches, that I tried on at Macy's, were huge and they looked absolutely ridiculous on my smallish wrist like the Casio Men's GA110RG-1A G-Shock Black Watch, and the Casio G-Shock Quartz Men's Watch GA201-1A I'm happy to say that the G100-1BV watch fit me perfectly bet, even though I do like an analogue display, I think it's a little hard to read on this watch. I will agree with other reviewers when they point out that the digital display is completed obscured from view, twice a day, at 6:30 am / pm. The reverse digital display is also not easy to read without the illumination (which will kill the battery). The G100-1BV watch is light and comfortable. The buttons are all easy to use, but not so easy that you might accidentally press one of them. The included manual tells you how to adjust the watch's analogue and digital displays, set the date, set alarms, etc. Overall, compared to other watches in the G-Shock line up, this is very basic. This doesn't come with a ton of features, just the simple stuff. It is a good looking watch, it's all black, it's comfortable, it's lightweight, it's rugged, and it tells time. It is just what I thought I was looking for. Unfortunately, some day, the battery will die and that will be the end of this watch. I like the idea of the solar battery feature found on other G-Shock watches, as well as the ability of other G-Shock watches to sync with the atomic clock every night (but you have to put your watch in the window at night for this to take place with the 12 o'clock facing up). At $54, I think that the price is a little steep for the G100-1BV. If I had it to do over again, I might get the G9000-1V for $10 more. The G9000-1V also uses a battery that will die but, I think, it is a similar sized watch, offers more features, and it has an all digital display that is easier to read, plus, you get to have a MUDMAN! lol. I know I said I wanted an analogue display and that's what I got, but the digital display on some of the other G-Shock watches are easier to read than the analogue display of the G100-1BV, especially at night. I believe this watch is now discontinued because I cannot find it on Casio's gshock dot com web page so, you might want to take that into consideration if you decide to purchase this watch. ... show more

Pros: Quality watch for sure. Perfect combo of analog and digital if that's what you're looking for. Band is solid and comfortable. Personal Cons: While the actual case diameter is over 47mm, it has such a small face that it has the impression/look on the wrist of more like a 37-40mm watch.. (Picture for reference, my wrist is 7.5" diameter) Watch is probably perfect for someone looking for the smaller statured on the wrist, rock solid build of this G-Shock, but it wasn't for me. ... show more
