You're running late to a meeting, glaring at your wrist in disbelief that it's fifteen minutes past the hour. Are you really that late? Lifting the watch to your ear you hear the all-too familiar tick of its internal mechanisms. Yes, it works -- and you are indeed late. This scenario could soon be a thing of the past, mostly because the mechanical watches of tomorrow may not tick at all. Researchers at École Polytechnique Fédérale de Lausanne have created a new, silent oscillator that could potentially be used to make watches with fewer mechanical parts.
