Those aren’t Palin’s hands. Look closely at them. The back of the hands are extremely hairy. In all her the pictures that have her in a t-shirt, sweatshirt or casual there is no watch.
Unless they caught her during a workout, she doesn’t wear a watch. She wears a bangle on her left wrist.
Not sure it’s hair; I think it’s the way she’s holding her hands. There’s a couple of pics I found that show her hands are not baby-smooth; she’s middle-aged after all, and that’s the way our hands tend to look. ;) http://www.ibtimes.com/articles/160878/20110610/sarah-palin-movie-documentary-amc-one-nation-pictures-paul-revere-thatcher.htm Note particularly the one by the vehicle, wearing the NH sweatshirt.
Also, I’ve seen things on neither wrist, her right wrist, her left wrist, and both wrists.
Those might be sun freckles on the back of her hands. The same can be seen in the picture across her chest.
Wasn't she in sunny Arizona recently?
The watch comes and goes in the photo shoot.
