...Crystal Balls. A wave of fascination with the occult is noticeable throughout the country. It first became apparent a few years ago in the astrology boom, which continues. But today it also extends all the way from Satanism and witchcraft to the edges of science, as in Astronaut Edgar Mitchell's experiment in extrasensory perception from aboard Apollo 14. In this area, serious researchers in the field of parapsychology are increasingly interacting with devotees of such claimed occult gifts as prophecy and telepathy to probe the powers of the human mind. Indeed, the very word occult?denoting hidden knowledge, secret...

...styles and prices. No longer. Whole new types of watches have hit the $3-billion-a-year world market in the frenzied competition to lure buyers. Some of the new models are called "automatic," meaning selfwinding; others are battery-powered and are variously called "electronic," "solid state" and "quartz crystal."

The cost: about...

Late last year Bulova brought out an improved and cheaper version, the $395 Accuquartz, believed by many to be the best quartz watch on the market...
...minute hands. Bulova uses the electronic tuning fork developed in its Accutron watch, a battery-powered model that is just a shade less accurate than the Accuquartz; Timex employs a conventional balance wheel; Benrus, the Swiss and the Japanese use a "stepdown" motor. Linking these mechanisms to the quartz crystal is an integrated electronic-circuit chip, and U.S. electronic firms are enthusiastically moving to supply the chips to the quartz watch market. Japanese, Swiss and American watchmakers are buying theirs from such firms as Motorola and Texas Instruments...
