The second hand jumps every 4 seconds
I have a woman's Coach watch that I got about 6 months ago. It was working normally until one day this week I noticed that the second hand no longer ticks with each second. It now waits 4 seconds and moves 4 seconds on the watch. I wasn't sure if this is a programmed thing, a dying battery or something faulty. It still keeps time perfectly except I need the second hand for timing things at work.
Do you know what this could be?
