Complicated to solve: you have to keep the instructions at hand (you can download it from the Casio website, but for this we must find the module number is printed under the watch, well hidden behind the bracelet). The analogue and digital hours are set independently. They améliré the principle in the last G-Shock, but on this one, it's painful. (Highly get it over with summer time and winter time, the problem will be resolved.)
The bracelet fray after a few months. If you wear everyday, plan to replace it after a few months (40!). In addition, it absorbs perspiration: remember to clean it regularly. It's not worth it to build hyper-resistant watches if they are accompanied by a poor quality as bracelet, Mr. Casio!
