Is your battery indicator showing a full charge? Sometimes if it's not showing full then the sounds are disabled.

Do not lay the tweezers across any contacts as you may damage the watch.
First you need to examine your watch movement and find an AC point (contact). Use an eyeglass, as the writings can be very tiny.
When found, touch an AC point with one arm of tweezers and battery+ with another arm simultaneously.
Some watches needs to do that twice, so, to be sure, do that twice.
If you are not comfortable with tweezers, you can use a thin wire, connecting one end of the wire to AC point and another to battery+.
Each shortcut should last for 3 seconds.

Depress the recessed 'Adjust' button (top left side) which will get the time setting flashing. Then depress the button on the lower right side once to get to the 24 hour time option.
