G-Shock GA-B2100 Solar and Bluetooth "CasiOak" Quick Review

If you'd like to watch my In Depth Review of the G-Shock GA-B2100 and the Casio watches App which goes with it then you can follow this link. • The Bluetooth G-Shock ...
Casio's GA-2100 watches have been wildly popular since their introduction about four years ago. In the meantime, more than one hundred variations have been released with different colors and materials. The latest versions to catch my attention include "Tough Solar" battery charging and Bluetooth technology to keep the watch set to the correct time, right down to the second. Out of all the versions Casio has released so far, only two of the Solar-and-Bluetooth variations also have positive LCDs on the face of the watch (as opposed to negative or "reverse" LCDs). The two watches in this video are those two, unique models.
Many watch enthusiasts refer to these 2100 series watches as "Casioak" watches because they share a similar case shape with the Audemars Piguet Royal Oak watches. Personally, the Royal Oak watches weren't on my radar and, perhaps, the main reason for that is they are literally unbelievably expensive. (I challenge you to do a quick online search for the prices of genuine Royal Oak watches and then you can tell me whether you also find the prices to be literally unbelievable.)
One of the fun things about these Casioak watches is that they're amazingly affordable and, if you want to be adventurous, you can find lots of kits to modify them too. Perhaps you can make a "Casioak" look amazingly similar to a Royal Oak. In fact, in the next episode of The Good Timekeeping Show I will use a $109 kit to convert the darker watch in this video to a watch with a metal bezel and a metal bracelet. Stay tuned!
The watches in this video use module 5689. In addition to the Tough Solar technology they have G-Shock's legendary shock resistance and 20-Bar water resistance. There's a World Time mode, 24-hour stopwatch, 1-hour countdown timer, 5 daily alarms and an hourly signal. These can connect to smart phones or tablets using Bluetooth and the "Casio Watches" app. Those who prefer not to use the app will still enjoy almost all of the functions of these watches. The "Reminder" function is only available through the app and the automatic time synchronization is only available through the app. Otherwise, these watches are able to keep time with quartz accuracy of plus-or-minus 15 seconds per month.

I have the black one, it's such a great piece of kit, I love it!

[@JMK15]

Do you find the charge if difficult? I keep reading getting to high is difficult

[@2fargonedaytona128]

Is the Bluetooth spotty as I have read from a few reviews?

[@YourSoulDriver]

Nice video.I was never interested in the GA-2100 until they came with Tough Solar and BT. I bought the yellow one.The buckle is not plastic (6:49). It''s IP coated metal. That's why is $10 more expensive than the others.

[@AlexBaldwinFTW]

Amazing coincidence, you posted this the day I finally ordered this watch!

[@renobodyrenobody]

Can't wait for the next episode!!!

[@tydshiin5783]

I can't wait to see your mod, I want to see how heavy it'll be and how it'll feel on wrist Also iirc, all of the Bluetooth CasiOaks have metal buckles except the blackout one, that one gets the short end of the stick with plastic haha

[@GoodTimekeeper]

The metal kit I found on Amazon was from "Custom Oaks". The watch was originally about 52 grams on my kitchen scale but increased to 152 grams after the conversion. It's well balanced so it's still comfortable. And I think it looks great. I will post the video in a few days.

[@troutbassncat3025]

If the black Casioak had the lighter index's of the yellow one, if not bright white, I'd absolutely put it on my list. I consider the analog to be primary over the digital, and quick and easily decipherable time, regardless of time of day, is what I actually want from a watch. My GAS-100 is so blingy, that the LED makes it even worse, and if it had been available with white index's, I wouldn't be considering another watch because it only gains two seconds a month.

[@patricj951]

I agree about the indexes. I have the yellow 2100 and really like it. The black version has too dark indexes and hands which is boring. There is GA-2100-1AER model which has the same light grey indexes as the yellow, without tough solar though. I actually got both GA-2100-7AER and GA-2100-1AER and changed out the shells and straps between them with good result.

[@JMK15]

💯 agree. The back light in these two is a game changer.

[@chrisdavis3723]

Hello Mr. Anderson. I love your videos. I'm more of a Multiband6 fan and not Bluetooth. I did look at and think about purchasing the yellow square in this video as a fun summer option but decided to buy the GA-2110SU-9 since I found it on a great sale online :-) Quick question: Have you seen the Casio MWD-110H models? So far I've seen 3 variants that look really nice. I'm thinking about buying 1.

[@zackamanda9799]

I have 2 GA-2100 watches in my collection. They are the earlier versions without the Solar/Bluetooth. One is the GA-2100SKE clear bezel/band with a black face and negative display. The other is the RUBIX CUBE version , the GAE-2100RC , also with the negative display.

[@idletime]

G'morning Greg ☕☕ 😇 . I think you are officially the biggest CasioTuber on the ol' Interweb 😋😋 ...

[@patricj951]

I have the yellow. Awesome watch!

[@tonychen3368]

Those two are outstanding watches, you guys need to check out the GA2100FT-8A, it's a great watch.

[@dnystrom22]

The 2100 series (like the squares) are incredibly addictive collecting wise. I think I’m up to about 18 of them now, three of which are solar/Bluetooth. Like I mentioned on your last casioak video I really wish they’d release a 2100 Solar with multi 6 and NO bluetooth. I’d really like a 2100 solar to be my everyday wear but since it has bluetooth i can’t wear it at work.

[@GoodTimekeeper]

I would like to know if they’re working on a Multiband 6 version.

[@aliindrawan]

may I ask why your work does not allow you to wear a watch with bluetooth connectivity?

[@muhammadfaheem3746]

​@@aliindrawanperhaps hes a radiologist

[@wpherigo1]

Thanks for another great video! I wish they had a solar, radio time version. I can’t wear Bluetooth watches in some of the places I work.

[@GoodTimekeeper]

If they release a Multiband 6 version I will definitely buy it… unless it’s some kind of super expensive, limited edition MR-G version.

[@pauljosephbuggle3722]

I wanted to get the black one but the good deal came on the yellow one. After I got it I came across the black one even cheaper. Such is life. I have a black strap on the yellow one so its a hybrid. The face on the yellow one is nicer and much easier to read because of the white number markers. Try swapping the bands around, you might dig it.

[@GoodTimekeeper]

I agree completely. The yellow one was available for a few dollars less when I bought it and then, later, the black one was on sale for just a few hours one day. So I ended up with both of them. And after I did the metal conversion on the black one yesterday (the video will be released next week) I tried the black strap on the yellow one, which was a simple swap using those quick-release spring bars. You’re going to think I took your idea but I honestly thought of it on my own yesterday.

[@pauljosephbuggle3722]

Haha! You have to be a genius to work that one out. It's a simple swap.

[@mrAThiker08]

got both and the green solar... plus 3 ga 2100's

[@TheFlyrodder68]

Looking forward to the mod. Thumbs up!

[@GoodTimekeeper]

I found a kit from "Custom Oaks" on Amazon and I made the conversion today. Very easy and I could easily put the watch back to its original condition too. But I think the conversion looks great. I'll post the video in a few days.

[@TheFlyrodder68]

@@GoodTimekeeper Sweer, I'll look that up. Thanks for the info! You rock!

[@branko8154]

I own black one. Big minus for me is that these can’t show date and day of week at the same time

[@Chrishagen]

Yes, would rather have day of week and date in one view, instead of seconds.

[@srbh90shan]

True.

[@jeffmanoppo7116]

Only date, month and seconds

[@stud1ounderd0g]

An all metal one is on my list!

[@smartcar8]

Hi, I have a question. When I sync my GA-B2100, it is off by 15 seconds compared to my G-Shock 5610. The difference is roughly 15 seconds. I believe the 5610 shows the correct time as it syncs with the atomic clock and syncs with the time on my cellphone. Any ideas on how to correctly sync the GA-B2100?? Thanks!

[@5843zman]

Great review. I have the yellow one. Do u have a link to where u got the metal bezel and strap mod? Very addicting watches. I love the solar function.

[@GoodTimekeeper]

This is the item I bought. a.co/d/eqblsSN

[@AnhBui-xz7mp]

hello, is there any way to adjust the hour hand alone? Thank you

[@frankgerace5997]

I have a “regular” (non-solar, non-Bluetooth) Casioak..I’m REALLY tempted to get this model, partly because of the positive digital display, which my Casioak DOESN’T have….

[@bdille]

if there's no multiband 6 then what's the "RCVD" display for?

[@uglyhatedchildkim6877]

Is it possible to see both date and day of week AT THE SAME TIME on the display?

[@prashanthpeter9640]

Anyone knows that in ga b2100 auto light is available (raise up light ) if yes then please share how to set it

[@bimerbomer2241]

tough solar is perpetum mobile idea but mechanical parts in watches make their life time much less , they should make emulated analog screen in these watches ( like garmin do) that would be much more accurate for me

[@mentaloveyt]

when gw atomic?

[@JMK15]

It must be white trim around the hands on the yellow, but they look bigger. I live the markers in the yellow. Just strongly dislike the black inked advertising all over the watch. But maybe a highlighter can tone down the black ink.

[@Rafal.L]

Die gelbe hatte ich auch. Aber die sah aus wie eine Spielzeug Uhr. Sonst ist Casio die erste Wahl beim Uhrenkauf

[@GoodTimekeeper]

The yellow one makes me think of watches from the 1980s like the Swatch brand. The black one looks better in person than it does in photos.

[@aaannkit]

Can i remove seconds and put day like monday tuesday and in botton date and month

[@aaannkit]

Anybody?

[@bikegeist]

@@aaannkitSomeone who owns one commented above that it's not possible, unfortunately.

[@starofdavid4586]

Don't kid yourself ,just buy the Royal Oak😀

[@GoodTimekeeper]

Or buy about 360 of these GA-B2100 watches for the same budget. Almost a new one for each day of the year!
