That is not a Rolex Thunderbird... Don't know why it's labeled as such. Below is a picture of my Gen Rolex Thunderbird. It's a datejust with a white gold turnograph bezel. The turnograph bezel is what makes it the Thunderbird. It was named as such because the USAF awarded Thunderbird pilots with this particular style of watch. I just wanted to help you with a little bit of Rolex history.
