Let’s face it, when you’ve got a watch with as many features as a Casio, finding your mode can be exhausting (and painful on your fingers). That’s why Casio came up with the GA-400GB series.
The GA-400GB-1A is completely black, with silver writing and a black and silver display. It’s analogue and digital, so the display is extra-large.
As with the GA-110 series, Casio made sure that the digital part was as easy to see as the analogue, with the date at the top, and the time at the bottom. It’s a negative display too, making the silver numbers stand out.
The watch has a rotary switch, which enables you to simply move the wheel up or down to find the mode you’re looking for. Much easier on your fingers than pressing a button 10-15 times!
