Your watch is called a chronograph. Not only does it tell the time but also has a stopwatch. It also has the day and date. To set the day and date is different on different brands of watches. I will give the common method. At 3 o'clock is a 'crown'. You can pull the crown out. There are 2 positions. You want to pull it out to the first position.Now rotate the crown several turns, you should see the day or date change. Now rotate the other direction. You should see the day or date change also. This is how most watches set but not all. Let me know if this works or not.

mcdevito75 here, Try re-setting the entire watch, re-set everything, hour, minute, day, date etc.

I just bought a Sportline 241 last week. The instructions are as follows. Note that there are no instructions for setting the 12/24 hour time option. Mine is in 24 hour mode (which is what I wanted), but I do not recall if it arrived that way or if I stumbled onto this mode when setting the time/date or alarm functions.

I hope this helps.
