CasioGA-B2100-1AER Digital Quartz Black Watch

I followed the information and downloaded the casio app first. Then I added the watch to the app. The watch connected easily and works well. It looks great, feels good, is easy to read and the light illuminates the whole dial. I'm really happy with this gshock.I bought a 5610u but gave it to my sone because my eyes are not as good as they used to be. This GAB2100 gives me a gshock that I can read without changing glasses. Delighted with this watch.

Very cool watch. Durable, stylish, comfortable and small size. Amazing, looks like an ordinary 4-5 dollars watch but the functions are totally different. Definitely recommend it !!

Watch choices are deeply personal, so what works for one person may not for someone else. I wanted a practical watch that did not need a battery, automatically adjusted to the correct time, had a stop-watch, and was waterproof and lightweight, but not overstated or "screaming" digital watch. The range of Casio G Shocks offer options to fit this bill. I like the octagonal design here. This model has different colour options, but only the yellow and this black offer a display with dark characters on a light background. Properly setting the watch up requires a bluetooth connection to one's phone, but this was straightforward, at least for me. Downsides - the analagoue hands are not particularly photoluminescent and the display is a bit small and can be obscured by the hands.I wear this watch daily apart from more formal occasions. It ticks the boxes for me, but YMMV.

Best watch ive ever bought & didnt break the bank

Wear this watch on a daily basis, my 18 year old Casio Waveceptor GShock as been relegated to outside working etc. (though it still works perfectly but I wanted a change). Setup was easy but found the phone app. was slowing my phone so I have uninstalled it. Also phone app said there was an upgrade to my watch to install but could not do so because watch not sufficiently charged even though I am wearing watch on a daily basis and it is showing a "medium" charge rate.

Really good light weight comfortable easy to see never wrong charges of the any light. Come on what's not to like

I bought this watch as I plan to modify it to a "CasiOak" in time, but I was hoping I could wear it "as is" for a while first, depending on the condition. Having bought it as grade "used-acceptable" from the Warehouse I had limited expectations but high hopes - and i could always return it if unhappy. The watch arrived in 24 hours, and the box was a little bent and used, and there was no original branded tin container. However i'm delighted with the watch itself, as the condition to my eye is absolutely spot on perfect. I'm wearing it now and thinking about the options open to me for it to be modified. I bought the bluetooth/solar version for the benefit of saving on future battery upgrades (my last Casio took 4 batteries!) and to sync with my phone. All works exactly as i'd hoped, and i feel that it was priced perfectly.

Easy to read. Comfortable to wear. Editing settings through your smartphone is extremely useful and great to know the time is always correct because it syncs with your phone. The solar charging is a fantastic feature and so easy, requiring just a few minutes of light a day to maintain a high charge.
