My watch has model number 504-tsk085, labeled Timex 1440 Sports, and Timex provides the incorrect manual for it online. I wrote these instructions after careful experiment:

Upper left button: press to switch to a stopwatch, or...

Press and hold to enter alarm setting mode. Once flashing press again to enter time/date setting mode.
-- you can only do one or the other without exiting the setting
mode (time or alarm set).
- within the setting mode you use the two right side buttons
in obvious ways to set times/dates
Exit setting mode by pressing upper left again

Lower left button: light
Upper right button (when not setting time): reveal date while pressed

Lower right button (when not setting time): reveal alarm time while pressed.

ALSO: WHILE lower right button is pressed you can change alarm
on/off and chime on/off through the four possible settings by
secondarily pressing the upper right button repeatedly.

You probably need to go to a watch repair professional. Any business that replaces watch batteries should be able to help you. They have a special press designed to support the watch safely while they snap the back onto the case. This sometimes takes quie a bit of force and rqeuires that the watch case and back plate be perfectly aligned.

In "Time Mode" when time is displayed, hold the "mode" button until the alarm flashes. Press the "mode" button again and the display should change to the seconds flashing. Press the st/stop button to change location between seconds, minutes, hours, date, month, and day. Use the lap/reset button to make any changes.
