Anyway, he's developed a bit of a pecking order for my diver's, and goes as follows:
The "open watch":

This is Paul's favorite, and the one that he wants me to wear when I put him to sleep. I'm sure you all can figure out how he came up with the name for the KonTiki, and he gets a special kick out of popping the case out of the bridge, as well as the killer lume.
The "zoo watch":

I wore this to the Central Park Zoo once, and now the Aquatimer will forever be marked as the "zoo watch". As such, whenever we go to the zoo, the Aquatimer must be on my wrist lest I incur his wrath.
The "aquarium watch":

There's a seal etched onto the caseback, and there are seals at the aquarium. Do the math ;-) And yes, I have to wear this one when we go to the aquarium.
The "blue circle watch":

Again, this one is kind of obvious. I will confess that I'm a bit disappointed that it isn't his favorite since it's mine, but c'est la vie.
The 'black watch":

He's three you know, so don't expect Plimptonian levels of wit here.
And there you have it. I'm sure he's working on names for the JLC and the Rolex, but he's playing it close to the vest at the moment.

(a classic "yogi" shot with my bao bei and the vehicle I seem to be driving the most these days...)

PS - Apparently daddy's Inge and B-1 are beneath contempt given their non-diver status, and as such, lack names.
