IRONMAN Triathlon, 8 Lap Memory Quartz Watch
Interesting here is that the case back
and the circuit board carry the movement number M746
M most likely stands for movement and this is the first Timex case back that has the movement number stamped in. As I mentioned before, the battery CR2016 was running 7 years inside this movement. That is a great performance for a digital watch with Indiglo. I have not used Indiglo a lot, because I have not worn the watch too many times. But still, it must be a very well design circuit providing so little drain.
