As we can see, Casio is favoring LEDs instead of EL for some of their newer watches. The same trend applies to the Duplex Display as well, as they are favoring displays without duplex. So far none of the (as far as I know) V3 triple sensor watches use duplex, including the PRG270, PRW3000 and GW9400. While duplex is just a gimmick for non-sensor G-shocks, it's quite a useful tool for an ABC watch, especially for the Compass. It's an excellent representation of the compass rose, very close to using a needle/hand for point at directions and much better than using tick marks on the outer edge of the display. Really like to see it's come back with the latest V3 sensor. Or am I just dreaming?
