Orange Hand Rolex Explorer II
Jack Hanna is one of the most famous wildlife experts, and animal rights activists in the world. He is a naturalist and zooloigist and the Director Emeritus of the Columbus Zoo and Aquarium, and served as the Director of the Zoo from 1973 to 1993. He is commonly referred to by his nickname of "Jungle Jack", and is well known for his appearances on The Tonight Show with Johnny Carson, as well as with David Letterman.
"You have to touch the heart, to teach the mind."
Jack Hanna wears a Rolex Explorer II "Orange Hand", with the Polar White Dial, which is my favorite currently offered Rolex model, and I think it looks fantastic on him. Also, I might point out that Jack Hanna's energy very much reminds me of Jacques-Yves Cousteau, in that they both share a serious spirit of enquiry and exploration.
