Philip Stein Teslar Watch, from 2008, works but needs a battery replacement. When working properly, the watch has "natural frequency technology" that resonates with the body and strengthens its biomagnetic field. This watch has been said to promote relaxation, health, and wellness because of its technology. The watch has a purple band and is 8 inches in length, 5/8 inch in width. Original packaging, pillow, box, and instruction/info/repair manuals included with the purchase. A fourth pamphlet describes how the natural frequency technology works. Included in the purchase also is a watch band spring bar tool that allows the the owner to remove/replace the current watch band. Tools not included with this purchase are necessary to change the battery. See links below for info regarding the watch:
