Fashion and function have become one in Philip Stein TESLAR watches. Termed by wearers as the “feel good” watch, TESLAR technology has changed the way people think about watches. Invented in 1986, the TESLAR technology was designed to emit a unique signal that strengthens the body’s own natural electromagnetic energy field and helps reinforce the body’s energy field to better resist the potentially negative effects of external, low-energy electromagnetic fields (EMF) given off by cell phone systems, computers and many other electronic devices.
