I have both a PAM 111 and a Planet Ocean 2201.50.00 42mm.
I got the Panerai first, and the Planet Ocean latter on and I love them both.
I wouldn't give up either one for the other, they are just diferent watches with it's own charisma.
First the Panerai to me is already a classic watch, with all it's roots and DNA from the days at the Marina Militare,
then the Planet Ocean is a nice modern sport watch that also looks good dresed up, with the hints it took fron the legendary Seamaster 300m,
one day it will be a classic too.
I don't thing about how old they are, or how much they cost, I think about how much happy I'm with them.
I enjoy switching from one to another, and I hope never have to depart from them, nobody knows.
Thinking about children, I would put it this way: If I had a calm, serene and thoughtful son, I would give him the Panerai.
On the other side, if I had a playful, outgoing, adventurous son, I would give him the Planet Ocean.
Oh! And I would love both of my sons!!!
Best Regards.
