Because a watch is round, you will compare it to a Rolex?
Come on!
You could also compare it ot a Heuer Silverstone, by the way.
No, it is, obviously, a daughter of the seventies, an era when all wasn't ( and didn't turn .. ) necessarily round.
When shapes were breaking the classic round, sensual cases... And not only for watches, but also for cars, and many other examples.
Yes, the seventies brought the Nautilus, the RO, but also some other watches ( have a look at the JLC of this era, Heuer, Breitling, and so on ... ) .
Sorry, but the world doesn't turn only around PP or AP, not all the watches have to be compared to these 2 references, there were much more attempts, at this time.
This one is one of the expression of the Seventies. You like or, or you don't, it is very subjective.
Personally, I don't like it, but it is just my taste, as I don't like the Heuer Silverstone, for example.
That doesn't mean that it won't find its fans.
Best,
Nicolas.
