Casio Edifice EFR-304 Watches

The EFR-304, like other similarly designed models, has one function that explains everything – the world time function. Yes, this design is adjusted to the function [so that the watch gets at least some feature]. How else to attract attention? There are no advanced technologies, and there are not enough other possibilities. So we started to make a marketing “trick”. We added an airplane to the second hand as if hinting at the spirit of travel and you’re done.
