After spending last year traveling the globe with world-renowned aviators, Breitling’s first (of 500) Naval Centennial Limited Edition Airwolf timepiece is being auctioned online to benefit the National Flight Academy. The auction will close at 5 p.m. EST on February 29. The first-off-the-line watch was worn by aviators in a global journey that started with Commander Mark Kelly on Space Shuttle Endeavour’s last flight into space in May. The highest bidder will have the watch, as well as an official Aviators’ Flight Log Book that accompanied every pilot on each individual flight, personally presented to him by Kelly.
