## Description

Men's watch from the brand CASIO. Model 01 G-SHOCK. Reference GA-B2100-1A1ER

Review: A great watch with solar and Bluetooth, read for a brief review - I am a 13 year old, and I was searching for a good g shock. I been looking for over a month and since the starting I saw this model, at the end I bought the one I saw in the beginning but only different colour. The watch is wonderful, great from every aspect. It is real also as it connects to the Casio app. It has a neorbite layer on the hand so it glows after being left in light for seconds! Its case is made of carbon and resin its backplate also shines when kept in light which looks cool. Length is 48.5 × width is 45.4 × depth is11.9 mm. It has feature like reminders stopwatch and even settings. The Bluetooth connection is a game changer for easy usage as manual setting of timers and alarms and other features take hours, while in the app it takes seconds, and tough solar is a good thing to flex at, and is also very useful as even if you use it for 15 years you won’t need to replace the battery if taken good care of. It has two super illuminator lights, the lighting might look cheap as you might think ther is no backlight but that is not the case. It has an accuracy of + or- 15sec per month without connecting to phone. It also runs 7 months without being exposed to sunlight after full charge. It also has a power saving mode and you can mute the watch. It anlso doesn’t need that much care except for cleaning and not using while using soap or detergent and things like that and not going to put it while going to high humidity places like the sauna. Its resin parts are so smooth to rub against, it feels so good. Anyone across the room willl know you are wearing a shock. Other features Hand shift feature (Hands move out of the way to provide an unobstructed view of digital display contents by pressing mode and light button at the same time for 2-3 seconds.) 12/24-hour format Date/month display swapping Day display (days of the week selectable in six languages) Regular timekeeping: Analog: 2 hands (hour, minute (hand moves every 20 seconds)), 1 dial (battery level, mode) Digital: Hour, minute, second, pm, month, date, day So overall it is a good watch.

Görseldekinden farklı rengi gelmiş olmasına rağmen iade etmedim. Bana gelende kadranının içindeki tüm parçalar siyah değil.
