Combined wrist watch and calculator - has data input keys incorporated in bracelet segments including circuit boards

摘要

The combined electronic wrist watch and calculator has a bracelet formed by a series of linked segments. Each segment is made from plastics and is in the form of a trough into which a flexible printed circuit can be placed. The edges of each segment have flaps which initially face outwards and which can be folded over the inserted printed circuit to act as the data input keys (5) for the calculator. A cover plate (19), with apertures through which the data input keys (5) project is then fitted over each segment.
