Yet here comes a definite imposter.
Take a look at the Iron Samurai red LED watch and you’ll see that it features standard digits.
OK, so the fact that the hour is displayed above, and not next to, the minutes might catch a few people out, but it’s not rocket science.
I suppose you could fool people into thinking you’re just wearing a chunky bracelet.
If you need something a little more complicated, but still red, check out the Alpha Centauri red LED watch instead.
