Beep and chime will not work

IndiGlo uses a separate battery as the watch has two. Take it to a local jeweler and have both batteries replaced.

How To Change CR2016 Battery In Indiligo Timex Watch

Oct 15, 2010 - Wondering how do you change a CR2016 battery in a Timex Idiglo watch? Changing a CR2016 battery in a Timex Indiglo watch is not a hard ..

press and hold the upper left button which is set, the seconds blinks then press the mode button/the lower left button until it reaches the chime turn it off pressing the middle button once. if your done press the "set" or upper left button. i hope i had been helped you.

Same thing happened to me, took watch to watch shop, they changed the battery and the chimes stopped working. Simple fix, the faceplate was put back on wrong. Unscrew the face plate and turn it upside down (or right side up depending on your POV) the circle on the inside of the faceplate will line up with the springs inside the watch and the chimes will start working again. If you have a pair of eyeglasses screwdrivers, like I did, you can do this yourself.

Quite possibly thr spring fell out when you changed the battery.

Press Mode till you are in Alarm setting
Press and hold split/start button till you hear the double beep. You should also see a small clock icon above the last digit of the seconds... you are all set. Repeat to deactivate hourly chime.

They should have reset (AC) the watch when the battery was replaced. If not you should have them do it for you. You should also be sure the watch is resealed and pressure tested to maintain water resistance.
For manuals you can download from the Timex website. The manual will tell you if/how the chimes turn on and off.

I removed the battery myself, and underneath are 2 metal prongs. One was bent down and not touching the battery. I pulled both of them up so they would touch the battery, and now it works fine.

I have a Timex Men's Classic Digital Silver-Tone Expansion Band Watch #T78587. To turn the chime on and off on this watch, I press the Start/Stop button on the top right once. This toggles the chime on and off. If you hear a single beep then you have turned it on. If you hear no beep you have turned it off. You can tell the chime setting by looking at the colon seperator between the hours and minutes. If it is flashing then the chime is on and if it is not flashing then the chime is off. This is not explained in my watch manual nor in any of the manuals I downloaded from Timex.com.

got a new battery in ironman and the beep will not sound when i press the start and end button on while in stopwatch mode
