Aerious is a pilot's chronograph by Erhard Junghans.

During the restart by Erhard Junghans after the takeover by the local owner family Steim the brand in 2009 promptly begins with hopeful watch creations including the pilot's chronograph full of character, with the beautiful name Aerious (aerius Latin for “airy”). The watch impresses by a strikingly clear dial, that by its symmetrical totaliser arrangement evokes associations with an instrument panel, and by the unusual arrangement by crown and pushers - properties, which promptly lift it above the bulk of all the same old pilot's chronograph.
