Being a fan of the brand "CASIO" I describe this magnificent watch as a guarantee of quality for having had for many years without any worries set apart change the reliable and robust battery this beautiful object is the joy of a man like I who love beautiful objects However being a birthday gift, I had the unpleasant surprise to find that the golden colors degrades very quickly which is a shame for a watch of this quality, and no return is possible after 30 days .. ?? I have worn the watch twice and frankly my disappointment and greatly justifié..je would not recommend this quality article very average rather buy the metal or steel version ....
