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

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.
