How do you replace the battery - Timex Ironman Triathlon 50 Lap Digital Watch

extra timex ironman watch battery replacement tips:
Buy watch batteries on amazon, they are 5 for the price of 1 at wal mart. $6.95
The dollar store was $4 for 1 and that is another option.

the gold spring must be above not under the metal ring that holds the batterry.
the disc on the back of the casing is the speaker!
That spring must contact the gold metal spring or the speaker wont chime

sometimes you can put something together, and it all appears right, but it still doesn't work. This happened t o me.
I took it apart again, and put it all back together seemingly the same way, and the 2nd try worked, but i don't know why.

make sure it is fully functional before screwing the screws in.

Put the back on without having the screws dangling from the wholes. I tried to insert the back and the screws at the same time and one of the screws flew at me and almost in my mouth! extra timex ironman watch battery replacement tips: Buy watch batteries on amazon, they are 5 for the price of 1 at wal mart. $6.95 The dollar store was $4 for 1 and that is another option. the gold spring must be above not under the metal ring that holds the batterry. the disc on the back of the casing is the speaker!
