The EFR-104 doesn’t have as many [dubious] features, so it got rid of the extra counters and side buttons. There is only a date and day of the week display plus a so-called crown. Pay attention to the steel models: the crown protectors are presented in black, which creates a certain contrast [and this is the first time we see such a design decision at Edifice]. There is also a cover with a screw lock [the screw connection on the base of the case optimally protects the internal mechanism of the watch and at the same time provides easy access, for example, when changing the battery] and a neon display [luminous cover provides long-term backlighting in the dark after a short exposure to light].
