  • Patent number: 4183206
    Abstract: A portable watch and compass device is provided which has a separate housing for the watch and compass. The housing for the watch is arranged above the compass housing and is movable about a hinge axis extending parallel to the longitudinal extent of a person's arm wearing the watch as a wristwatch. With the housings arranged one above the other and separately from one another, and with the further provision of a mirror at the underside of the watch housing, the watch housing can be selectively hingedly moved to an adjusted open and locked position to accommodate convenient reading of the compass without interference by the watch face characters and the like.
