Abstract
A jointed electronic watch comprises a plurality of watch cases each capable of bearing a different type of display and an energy source. Between the back covers (4, 5, 6) and case bands of each case are sandwiched seals (9, 10, 11) which are coupled together by isthmuses (12) at the line of articulation of the back covers and which are formed as a single piece. Within the isthmuses are arranged electrical conductors adapted to couple together the various electronic components within the plurality of cases.
