I haven't used my watch in a month or so and now it won't turn on. All I get is a squiggly line with the charger circle on the watch face it just blinks on and off. It worked fine when I put it away. It was fully charged when I put it in the box. But like I said I haven't used it in a month or so and now it won't power up except for the squiggly line with the power charger circle. I don't know what to do now. Any ideas?
