It's been almost a year since I wear it every day and nothing to indicate battery level and precision, it is always accurate to the second as she was receiving my package. Just before this purchase I wore a Lotus Code Titanium had a featherweight, this weight is perhaps the only thing I wish I had the Casio, but I knew what to think by taking a watch steel. The setting is in turn can be a bit tedious at first but honestly it is not necessary to have a bac + 4 to get by. A little common sense and a good read of the manual (found in French and in large format on the official website) are used to get by in minutes. Really satisfied and I highly recommend this watch. I do not hesitate to direct me again Casio to the day when I will want to change.
