How to set to 24hr mode for timex 1440 sports

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.

Press the MODE button.

Then hold and press reset/lap button for 2 seconds.

Press mode button again.

Press Start/Stop to set the Hour.

Press mode button again.

Press Start/Stop to set the Minute.

Try the link above for a manual.  It is NOT the same watch, but does have some buttons named similarly to the 1440.  Go to the Time and Date section.  The key was to hold down the SET button till the seconds flashes, then use START/SPLIT to adjust the value and MODE to toggle to the next field etc.
Best of luck
