The second hand of my Tissot wristwatch model T870/970 stops for 4 seconds, then moves quickly to the next 4 second marker, stops for 4 seconds again, and again moves quickly to the next 4 second marker(as if to catch up) and so on.The watch still keeps accurate time (The hour hand and the minute hand are still working).When I'm not using this watch, I usually pull the crown to stop the watch(I read somewhere that this helps prolong battery life.Is this true?)
