Philip Stein and Teslar technogology have introduced the watch world to a new way of thinking about watches. The Teslar technology dates back to 1986, and consists of an apparatus in the watch that emits a unique signal designed to strengthen the body's own natural electromagnetic energey field, to better resist the potentially harmful effects of electromagnetic field radiation found in cell-phones, computers and other electronic devices. Teslar watch wearers describe it as the 'feel good' watch. Past wearers have experienced deeper and more restful sleep, enhanced calm and reduced tension, improved concentration, elevated energy levels and all-around feelings of well-being. The Tesla watch has garnered significant celebrity support, including Oprah Winfrey. The watch is named for Nikola Tesla, a pioneer in the field of energy science.
