Here is a very interesting Gruen Air Flight. The hours are indicated on the disc positioned behind the dial. The dial has 12 apertures showing the hours on the disc. At 1 P.M. the disc will rotate a bit and the hours will be indicated as 13 to 24. At 1 a.m. the disc will rotate again showing hours as 1 to 12. The case is chrome plated with a stainless steel back. A bit of the plating is off in a few small spots on the back of the case. Original dial and hands in great condition. Manual movement works great. Priced at $1000 Make Offer Text 702 526 8524
