In my mind G-Shock is a brand of watch and there are many different ones.
So the statement “Casio releases a G-Shock watch with fitness features” makes sense. “Casio adds fitness features to G-Shock digital watch” also makes sense. The “original” is a bit confusing to me. And judging by the comments here others, too.
I get why it’s in the headline. This fitness watch is sort of styled like the very first (= “original”, though given the plethora of G-Shock watches and their enormous diversity that seems like a weird way of framing it) G-Shock watch from 1983.
Maybe “Casio releases 40th anniversary G-Shock watch with fitness features”.
