like all Casio products, watches are of high quality, accurate, and the controls are intuitive. I hope the solar battery is not a marketing ploy, but really long-term support for the power source. The last watch, with a declared battery life of 3 years, worked for 6 years for 3 incomplete seasons (about 15 years), which was a pleasant surprise. I think that in its price category the choice of this model is optimal.
