Steampunk, it originated as a type of fiction based on an alternate reality of Earths 19th century, but the workmanship of these science fiction phones is quite amazing reports slashgear

Apparently standard Steampunk creations have a basic feature set and made from standard materials such as brass or copper, word, glass and even leather. No idea what this manufacturer used to create this mobile phone, but it does appear to incorporate glass and a riveted metal casing.

There is an industrial compass there and some kind of pipe on the side, for all that steam power no doubt. There is no word on how one would purchase such a contraption or even what price tag it would cost, probably an inordinate amount of universal credits no doubt.
