I wanted a "technical" watch, that is radio-controlled and solar if possible. No metal band (I think it is in the hair accorche arm ...!). Also after long research on the net, I found Casio (easily) and Junghans (full assets) and Skagen (not solar). I purchased a Junghans (500), look a little austere (German!), Nice production (matt titanium, leather with folding clasp), but the second hand was too noisy for my taste (!). So back to the seller. I returned to this CASIO (if I had known I would not have wasted all that time), choose "simple" and a good price / quality ratio which I am perfectly satisfied. I've had more than a month. I did not put his nose in the user manual. She is always at the precise time and switching to DST was performed nickel. A star less so (but this is only a matter of taste) because the metal part is brilliant and the bracelet. I solved the problem by the Band "sanding" the green part with a sponge (to remove the "bright"). PS: the watch is more beautiful in person than on the website pictures. Good research!
