Just received my late delivery of two frogs, the 1000B and 8200NT2. I took their old brothers out for comparison. I am not sure whether other members have done it before. Anyway, for your reference.
Let's start from 1000 first:
Watches inside boxes
Side view: please note the two-tone colour of the 1000 where the 1000B is all black
Another side view: the difference in letter colour and push buttons
Band and bezel
Buckles: The silver is 1000 while the black is 1000B
Which one I like the most? My answer is:
Next is my NT vs NT2:
Inner boxes: NT has the letters 'Frogman 2000'
Frogs in boxes
Frogs out of the boxes
Frogs in hand
Frogs jump out of my hand
Caseback: No serial number, only NT2 punched on the caseback
Caseback: NT with limited number out of 1000
See the black coating on the titanium
Another wrist shot
In summary, only the caseback is different. If it is for wear, buy NT2 because it is cheaper. If you are a serious frog collector, NT is your choice because it is one of the rarest frogs in the pond. But if you are a die hard frog collector, then buy both.
