The only strange is putting both "TechnoChas" and "Elektronika", I don't get the meaning of both.
TechnoChas is the name of watch vendor (and maybe a trademark). Elektronika is what then? Trademark? Name of the watch?
Why put "Elektronica" on both face and back?
That's a question of design and copyright, that I just don't undestand, but I'm O'k with that.
