I believe it dates to the 1930s (prior to the merger with Jaeger). It features a round brass case finished in black enamel raised up on two conical brass feet that give the clock a rakish back lean. The face is gold with superb art deco Arabic numeral markers and is housed under a convex glass lens. The hands are blued and the hour hand has a circular cutout at the pointer end. The numerals and hands have lume but they no longer glow. The clock face is marked LE COULTRE, 8 in a circle, SWISS. The feet are engraved with an inscription that reads Aerial, Christmas1944. The case is about 2-3/4 in diameter. The overall height is about 3 tall to the top of the crown. (Note: measurements are approximate). It is in fair to good vintage condition. The clock winds, sets, and runs. With a partial winding it ran steadily for three days but ran a bit fast picking up several minutes. The brass elements have patina. The black enameling shows finger wear and loss around the crown. The glass lens is in nice shape, clean and clear with no damage. The gold face is in good shape. The lume is aged with some loss on the hour hand. It’s not a museum piece but it still presents fairly well.
