Here's one of the most inventive watches ever: A 1950s Gruen Air-Flight.
Check out the two-tone luminous silver-and-gray dial with the golden moon-style hour hand and the slashing sweep second hand.
At midnight, the hour markers change to 24-hour readings.
The stainless steel-backed, chrome-plated case is big for the day: 35mm wide excluding the unsigned crown by 41mm from lug to lug.
The case is in excellent condition with only a few light scratches.
Under the hood is a 17-jewel Gruen movement Cal N510 SS keeping excellent time.
