Not sure how long the battery sat in this watch before I got it. I thought the watch was broken but could not return it as it was beyond 30 days before I started using it.Once I replaced the battery that was inside the watch when I received it, the watch worked reliably.Not easy to open the watch for this, so be patient.Glad to have options to wear it on my wrist, on a lanyard or belt clip.
