The GRUEN Airflight Precision has unique switching or jump hour-windows that change mechanically at midnight/noon, to display 12-hour standard time or 24-hour military time. This particular Airflight is a rarer variant of the original or base model (see print advertisement to compare). This vintage piece is considered a coveted museum piece, which will definitely be a gem in any serious watch collector's collection!

GRUEN kicks the Airflight up a few notches by adding a rotating bezel & a two-tone dial with contrasting black windows.

The GRUEN Airflight was designed for pilots who need 24-hour reference for flight time. At noon, the windows switch to show a 24-hour time, at midnight the windows switch back to show 12-hour time. This feature is credited to a rotating disk underneath the main dial. The hours are displayed in alternating sphere/diamond-shaped windows.

Most GRUEN Airflights have plated cases but this particular variant has a stainless steel case!

The dial is original however, a fresh coat of clear fixative has been applied over the surface to give it a "new" sheen. Also, some of the letters in "PRECISION" have been reapplied because they were faded when we acquired this watch.
