The Heartbeat watch is a gadgety cool timepiece featuring a brilliant time reading system that mimics a heart rate monitor. You can push the button to display the time...or you can program the watch to stay on 24/7

LED watches are typically battery hogs and if you leave the watch on full time it will drain the battery in about 24hrs. Great News.....this watch is USB rechargeable!
