IRONMAN Triathlon, 8 Lap Memory Quartz Watch

Quite unbelievable, this battery (CR 2016 are great batteries) is still running after 7 years!
I did not wear the watch often and thus was not tempted to use the Timex Indiglo (which I love to play with when wearing the watch) backlight which would have drained the CR 2016 faster for sure. But still, that is a quite astonishing performance. Timex must have found a great chip supplier that is able to manufacture these low drain circuits!
